Margin is the amount you put up to trade without paying the full balance.
Initial margin (IM) is the value of your equity in the margin trade.
Maintenance margin (MM) is the minimum equity you need to maintain at all time.
Margin call (MC) is the amount that you need to put up to bring your equity back to the initial margin.

Short Selling and Marginsالهامش والبيع على المكشوف
Margin is the amount of cash you put up as a security against the increase in your liability due to short selling.
Initial margin (IM) is the value of your cash balance against the short sold position (liability).
Maintenance margin (MM) is the minimum equity you need to maintain at all time.
Margin call (MC) is the amount that you need to put up to bring your equity back to the initial margin.

Short Selling and Marginsالهامش والبيع على المكشوف
The position now is 12000 and the equity is 3000.
The drop in equity is equal to the difference between the initial position and the current position value.
That makes our margin below the 37.5% maintenance margin.
Cash is needed to go back to the initial margin.
1-28
Short Selling and Marginsالهامش والبيع على المكشوف
Need to add cash to the account to go back to 50% or as agreed with the broker.
The drop in equity is equal to:Current position – initial position
12000-10000 = 2000 The value of current equity is equal to
the initial equity – the drop 5000-2000 = 3000
The margin now is equal toCurrent equity/current position
3000/12000= 25% This less than the 37.5% maintenance margin. To go
back to the initial margin, we need to add cash to answer the margin call.
1-29
Short Selling and Marginsالهامش والبيع على المكشوف
To go back to the initial margin of 50% we need to make equity equal to half the current liability position:
IM*P1*N= 0.5*12*1000 = 6000 Margin call calculations:
Margin call amount = Current Equity requirement-Current equity
6000-3000 = 3000

Advanced Margin Calculations
حسابات هامش اكثر تعقيدا Margin Accounts can become very complex
especially if there are multiple diverse transactions.
An example would be to calculate the margin requirements for buying a stock on margin and short selling another.
Or, you may want to add to that some other securities purchased without the use of margin.
Or, add to all of the above margin calculations for futures contracts and options premiums.
Will revisit later on.

Segregation of Clients Accounts
فصل الحسابات Client Money is separated from brokers
money. Brokers can no longer use one client
money (free of charge) to lend to other clients for stock purchases.
Benefits: Lower risk. Enhance the availability of cash for clients
withdrawals.
1-33
Segregation of Clients Accounts
فصل الحسابات
Where does the cash go? To banks. Why then move the cash from
brokers to banks? Two reasons: Banks enjoy higher liquidity and
greater readiness to answer cash demand.
Bank capital is structured to have a component that accounts for these deposits, brokers do not.
1-34
Segregation of Clients Accounts
فصل الحسابات What are the problems with brokers
practice of using clients cash to finance other clients stock purchases? Risk of illiquidity Strains on leveraged brokers accounts No brokers capital rules to protect loans
made to clients using other clients money Brokers are not allowed to make such loans
by legal definition of brokering There are no regulations for margin trading
in place.
1-35
Segregation of Clients Accounts
فصل الحسابات
What are the problems of account segregation? - Lower liquidity for trading.
Well this liquidity is not allowed in the first place and markets should have never used this extra liquidity.
1-36
Segregation of Clients Accounts
فصل الحسابات If brokers are so concerned about this
lack of liquidity and they think it is not healthy to stay without it – then why not bear the cost of borrowing from banks to create this claimed extra liquidity?
In no way does the SCA condone or encourage brokers to do so, not until the regulations that deal with that are ready.
These regulations are being worked on and will be ready very soon.
1-37
Segregation of Clients Accounts
فصل الحسابات
So, to avoid this lack of liquidity, why didn’t SCA delay account segregation until after it had such regulations in place?
Well, SCA never allowed lending by brokers and such lending should not be happening.
1-38
Segregation of Clients Accounts
فصل الحسابات What is the difference between the current informal
lending and the lending under SCA regulations?Under current practice Under regulations The current lending is not allowed, it is not the brokers job.
Brokers are legally allowed to lend to customers to purchase securities
There are no liquidity guarantees to meet cash withdrawals
Such guarantees are embedded in the system
There are no capital adequacy rules in place
Adequacy rules will be in place and will be enforced to protect investors money
Current lending practices are very risky and can cause a disaster under very small liquidity strains
Lending will be more secure and mechanisms will be in place to keep things safe
There are no rules to ensure fair and equitable lending, personal connections rule lending
Lending is fair and equitable
Current lending can lead to improper practices like forcing unnecessary trading to make up for lending risk and lending compensations through generating transaction fees to generate income.
Income is generated in a safe and structured manner

Market Makingصانع السوق
Evidence shows that two of the main problems that emerging markets face are: Capital supply shortage and low liquidity
Market making is thought to be a good tool to remedy these problems.
1-41
Market Makingصانع السوق
The tools other than market making that are used to by emerging markets to remedy the above problems are: market segmentation (trading hours, main and
parallel markets), different trading phases (continuous and auction
trading), introduction of special incentives for submission
of limit orders (hidden reserve orders, standing orders, etc).
1-42
Market Makingصانع السوق
The implementation of the market making system contributes the following: promotes liquidity, lowers transaction costs, reduces volatility and improves daily turnover of the listed
securities
1-43
Market Makingصانع السوق
Four types of market making systems which are applied in modern stock markets: The quote-driven market making system, The centralized market making system in an
order-driven market – electronic The centralized market making system in an
order-driven market – Floor The noncentralized market making system
in an order-driven market.
1-44
Market Makingصانع السوق
1-45
Market Makingصانع السوق
Market making (dealer) system in a quote-driven, electronic market
public investors generally cannot trade directly among themselves.
In order for buyers (sellers) to execute an order they have to contact a market maker (dealer) who uses his/her own inventory in the transaction.
There is more than one market maker per company who announces on a continuous basis quotes to buy and sell a number of shares at a particular price.
Dealers compete among themselves for more competitive bid and/or ask prices that will attract the order flow from public
Certain exchanges prohibit the use of market makers for their high liquidity stocks. In LSE, the 100 stocks that belong to the SETS system are traded electronically.
Stock markets that apply this system are the NASDAQ and the London Stock Exchange (LSE).
1-46
Market Makingصانع السوق
Centralized market making system in an order-driven, floor-based market
All potential buyers or sellers can directly trade among themselves Requires the use of a single market maker that has monopolistic
information on both the market orders and the limit order book. There exist a floor, which is a physical location where market makers
reside and interact with orders that come electronically to their terminal and with orders that come from floor brokers.
Market makers are required to announce quotes on a continuous basis that reflect both the limit order book interest and floor brokers intentions
As a result, market makers only provide the necessary liquidity from their own account when there is a lack of either a buy or a sell interest.
Typically this scenario occurs when there is a temporary disparity between supply and demand that asks for the market maker’s intervention in order to come up with an equilibrium price.
Floor-based markets where a centralized market making system is applied are the NYSE and the eight stock markets in Germany (Deutsche Börse).
1-47
Market Makingصانع السوق
Centralized market making system in an order-driven electronic market
Same as the floor-based market with a single market maker in the centralized dual role of matching buyers and sellers and providing the necessary liquidity when needed.
The only major difference is that in an order driven market there is neither a floor nor floor brokers to interact with the limit order book for providing extra liquidity.
Such a system was applied in the Amsterdam Stock Exchange (prior to its inclusion in Euronext).
1-48
Market Makingصانع السوق
Non-Centralized market making system in an order-driven electronic market.
There can be more than one per company required to announce limit orders to buy and sell
on a continuous basis They do not possess any monopolistic
information on the incoming orders or the limit order book.
They compete with investors for order flow. This system is applied in Euronext, in the Italian
Stock Exchange (ISE) and in the Athens Stock Exchange (ASE), among others.

Costs and Challenges of Applying a Market Making System to Emerging Markets: Factors for Consideration
1. current exchange design and the costs of restructuring
2. current investors’ sentiment towards the exchange both domestically and internationally
3. the market design in countries hosting the target foreign capital
4. size of the emerging market.
1-52
Market Makingصانع السوق
1- current exchange design and the costs of restructuring
The least costly to implement in terms of both machinery and technical personnel and supplies, is the noncentralized market making system.
The quote-driven market making system is much more costly as it requires more capital for the system to be fully functional.
The centralized (especially floor systems) are extremely costly.
This should not be a major problem in the UAE.
1-53
Market Makingصانع السوق
2- Current Investors’ Sentiment Towards the Exchange - Domestically and Internationally
Market making has many requirements that are not currently available in the UAE, som of which are:
Experienced financial researchers Short selling, security borrowing, high liquidity,
derivative securities to hedge MM portfolios. Do we think of a centralized MM to be trust
worthy. Collusion is possible in Quote or non centralized
1-54
Market Makingصانع السوق
3- Market Designs in Countries Hosting the Target Foreign Capital
Are foreigners used to our system Do they trust our regulations and
market participants The answer is yes, due to
the increasing international interest in the UAE
the UAE’s ability to adapt to new systems, methodologies and technologies.

4- Size of the Emerging Market Looking at the capitalization of the
markets that employ either the centralized market making system or the quote-driven market making system, we observe that these are much larger on average than other markets that follow the non-centralized market making system.
The UAE markets are small once compares to quote and centralized markets
1-56

Conclusion: Noncentralized is the closest fit to
the UAE.

What Are Conflicts of Interest and Why Are They Important?
وأهميته المصالح تعارض تعريف
Financial intermediaries engage in a variety of activities to collect, produce, and distribute information. By providing large volume of each service the realize economies of scale and by providing multiple services, they realize economies of scope.
However, these services may be competing with one another, and this creates the potential for a conflict of interest (e.g. IBF and BF)
1-58
What Are Conflicts of Interest and Why Are They Important?
وأهميته المصالح تعارض تعريف
The conflicts of interest may arise as the concealment of information or the dissemination of misleading information.
We care about these conflicts of interest because a reduction in the quality of information increases the presence of asymmetric information.
This will lead to adverse selection and moral hazard
1-59
Ethics and Conflicts of Interestالمصالح تضارب و المهنة آداب
Conflicts of interest generate incentives to provide false or misleading information. This behavior is considered unethical.
One way to limit these conflicts is to make workers aware of the ethics issues at stake, so that they are less likely to engage in unethical behavior.
1-60
Types of Conflicts of Interestالمصالح تضارب أنواع
Four areas of financial service activities that harbor the greatest potential for generating conflicts of interest. These are: Underwriting and research in investment
banking
Auditing and consulting in accounting firms
Credit assessment and consulting in credit-rating agencies
Universal banking
1-61
Underwriting and Research in Investment Banking
ودائرة االستثمار بنكير دائرة لدى المصالح تعارضالمالية االوراق شركات في المالي والتحليل الوساطة
Some investment banks both underwrite new securities sold to the public as well as provide research (recommendations) to the investing public
When revenues from underwriting exceed brokerage commissions, favorable research will attract more business, at the expense of unbiased recommendations to the investing public.
1-62
Underwriting and Research in Investment Banking
ودائرة االستثمار بنكير دائرة لدى المصالح تعارضالمالية االوراق شركات في المالي والتحليل الوساطة
In initial public offerings of equity, underwriters direct the new shares as they wish, typically to their best clients or potential new clients.
Since most IPOs are underpriced, many of these shares are immediately sold for a profit (called spinning). This immediate “profit” may appear as nothing more than payment for future business.
1-63
Auditing and Consulting in Accounting Firms
شركات لدى االستشارات وتقديم المالي التدقيقالمحاسبة
The role of auditors in public firms is to provide an unbiased view of the financial reports to reduce asymmetric information between the firm’s management and the investing public.
By also providing management advisory services (such as systems support), the auditor has an incentive to fudge the audit if the fees from other services are substantial.
1-64
Auditing and Consulting in Accounting Firms
شركات لدى االستشارات وتقديم المالي التدقيقالمحاسبة
Auditors also have a conflict of interest since they are paid by the firm they audit. If the auditor gives an unfavorable audit report, the auditor may lose the auditing business as well.
A well known case of the failure of auditors to provide unbiased reports was Arthur Andersen’s audit of Enron.
1-65
Credit Assessment and Consulting in Credit-Rating Agencies
السندات تقييم مؤسسات لدى المصالح في تضارب
Bond investors rely on credit-rating agency assessment of firm’s debt (debt ratings).
However, ratings are only provided when the firm pays the agency. Agencies, then, have an incentive provide “better” ratings to attract business.

Rating agencies have also started providing firms with other services, and have the same conflicts as auditors in this regard.

Issuers that use the underwriting services of a bank will also benefit from sale of its products to the banks other (retail) customers. Customers should expect unbiased advice, but may not get it.
Bank managers may push investing products of its affiliates, even if they aren’t in customer’s best interest.

When Are Conflicts of Interest a Serious Problem?
خطرة مشكلة المصالح في التضارب يصبح متى
Conflicts of interest are a problem when they lead to a decreased flow of reliable information (increased asymmetric information).
However, even with potential conflicts, the incentives (financial gain) may not be present to actually act on them.

Conflicts of Interest: Empirical Evidence.
: عملية دراسات المصالح تضارب
Empirical evidence suggests that rating agency debt ratings are unbiased, despite being paid by the firms.
Underwriting and commercial banking also appeared to be free from exploitations. Many banks spun-off their investment banking activities to separate the functions.

Conflicts of Interest: Empirical Evidence.

Empirical evidence also suggests that the investing public recommendations are made by the underwriter’s analysts.
However, when temporary rewards to highly trusted firms may extract reputational rents from the investing public by seeking short-term gains at the expense of their future reputation.

Policies to Remedy Conflicts of Interest
لتضارب السيئة اآلثار من للتخلص سياساتالمصالح
A trade-off between potential conflicts of interest and economies of scale exists. Simply eliminating any potential conflict may not be the best solution:
1. The existence of a conflict of interest does not mean that the conflict will have severe consequences.
2. Even if incentives to exploit conflicts are high, eliminating the conflict may be worse if it reduces the flow of reliable information.

Efficient Market Hypothesisالسوق كفاءة فرضية
This equation tells us that current prices in a financial market will be set so that the optimal forecast of a security’s return using all available information equals the security’s equilibrium return.
. الاعتبار بعين المتوفة المعلومات كافة أخذ عند المتوقع العائد لمعدل مساوي المتحقق العائد معدل Financial economists state it more simply: A security’s price
fully reflects all available information in an efficient market.

Rationale Behind the Hypothesisالمراجحة عدم حالة هو الفرضية سبب
When an unexploited profit opportunity arises on a security (so-called because, on average, people would be earning more than they should, given the characteristics of that security), investors will rush to buy until the price rises to the point that the returns are normal again.
1-85
Rationale Behind the Hypothesis (cont.)المراجحة عدم حالة هو الفرضية سبب
In an efficient market, all unexploited profit opportunities will be eliminated.
Not every investor need be aware of every security and situation, as long as a few keep their eyes open for unexploited profit opportunities, they will eliminate the profit opportunities that appear because in so doing, they make a profit.

Stronger Version of the Efficient Market Hypothesis
السوق كفاءة لفرضية اقوى صيغة Many financial economists take the EMH one
step further in their analysis of financial markets. Not only do they define an efficient market as one in which expectations are optimal forecasts using all available information, but they also add the condition that an efficient market is one in which prices are always correct and reflect market fundamentals (items that have a direct impact on future income streams of the securities)

Stronger Version of the Efficient Market Hypothesis (2) This stronger view of market efficiency has
several important implications in the academic field of finance:
1. It implies that in an efficient capital market, one investment is as good as any other because the securities’ prices are correct. كافة

Stronger Version of the Efficient Market Hypothesis (2)
3. It implies that security prices can be used by managers of both financial and nonfinancial firms to assess their cost of capital (cost of financing their investments) accurately and hence that security prices can be used to help them make the correct decisions about whether a specific investment is worth making or not.

The “Investment Dartboard” often beats investment managers.
Mutual funds not only do not outperform the market on average, but when they are separated into groups according to whether they had the highest or lowest profits in a chosen period, the mutual funds that did well in the first period do not beat the market in the second period.

Evidence in Favor of Market Efficiency Do Stock Prices Reflect Publicly
Available Information as the EMH predicts they will? Thus if information is already publicly
available, a positive announcement about a company will not, on average, raise the price of its stock because this information is already reflected in the stock price.

Evidence in Favor of Market Efficiency Do Stock Prices Reflect Publicly
Available Information as the EMH predicts they will? Early empirical evidence confirms: favorable
earnings announcements or announcements of stock splits (a division of a share of stock into multiple shares, which is usually followed by higher earnings) do not, on average, cause stock prices to rise.

Evidence in Favor of Market Efficiency Random-Walk Behavior of Stock Prices that is,
future changes in stock prices should, for all practical purposes, be unpredictable
أألسهم ألسعًار العشوائية والحركة االرتبًاط عدم ظًاهرة If stock is predicted to rise, people will buy to
equilibrium level, if stock is predicted to fall, people will sell to equilibrium level (both in concert with EMH)
Thus, if stock prices were predictable, thereby causing the above behavior, price changes would be near zero, which has not been the case historically

Evidence in Favor of Market Efficiency Technical Analysis means to study past stock
price data and search for patterns such as trends and regular cycles, suggesting rules for when to buy and sell stocks
الفعًال السوق فرضية حسب للوقت مضيعة التقني التحليل The EMH suggests that technical analysis is a waste
of time The simplest way to understand why is to use the
random-walk result that holds that past stock price data cannot help predict changes. Therefore, technical analysis, which relies on such data to produce its forecasts, cannot successfully predict changes in stock prices

Implications for Investing1. Should you be skeptical of hot tips?
الى تؤدي التي السرية االخبار مصداقية في نشك هلالسريع؟ الغنى
YES. The EMH indicates that you should be skeptical of hot tips since, if the stock market is efficient, it has already priced the hot tip stock so that its expected return will equal the equilibrium return.
Thus, the hot tip is not particularly valuable and will not enable you to earn an abnormally high return.
1-101
Implications for Investing
1. Should you be skeptical of hot tips? As soon as the information hits the
street, the unexploited profit opportunity it creates will be quickly eliminated.
The stock’s price will already reflect the information, and you should expect to realize only the equilibrium return.
1-102
Implications for Investing Do stock prices always rise when there is
good news?
؟¬ دائما جيدة اخبار توفر مع ايجابيا االسعار تتفاعل هل NO. In an efficient market, stock prices will
respond to announcements only when the information being announced is new and unexpected.
So, if good news was expected (or as good as expected), there will be no stock price response.
And, if good news was unexpected (or not as good as expected), there will be a stock price response.

Implications for Investing Efficient Markets prescription for investor
صغار تنصح الكفؤة السوق فرضية فان التحويل تكاليف من وللتخلصالمتعددة لفوائدها االستثمار صناديق في باالستثمار المستثمرين
It is frequently a sensible strategy for a small investor, whose costs of managing a portfolio may be high relative to its size, to buy into a mutual fund rather than individual stocks. Because the EMH indicates that no mutual fund can consistently outperform the market, an investor should not buy into one that has high management fees or that pays sales commissions to brokers but rather should purchase a no-load (commission-free) mutual fund that has low management fees.

Behavioral Finance التمويلالسلوكي Dissatisfaction with using the EMH to explain events
like 1987’s Black Monday gave rise to the new field of behavioral finance, in which concepts from psychology, sociology, and other social sciences are applied to understand the behavior of securities prices
االفراد سلوك باستخدام االسعار في التغير تفسير تحاول النظرية هذهوالمجتمعات
EMH suggests that “smart money” would engage in short sales to combat overpriced securities, yet short sale volume is low, leading to behavior theories about “loss aversion”

Why Should Capital MarketsBe Efficient?

The premises of an efficient market A large number of competing profit-

Evidence Against Market Efficiency Market Overreaction: recent research
suggests that stock prices may overreact to news announcements and that the pricing errors are corrected only slowly
الجديدة للمعلومًات الفعل ردة مبًالغة ظًاهرة When corporations announce a major change in
earnings, say, a large decline, the stock price may overshoot, and after an initial large decline, it may rise back to more normal levels over a period of several weeks.
This violates the EMH because an investor could earn abnormally high returns, on average, by buying a stock immediately after a poor earnings announcement and then selling it after a couple of weeks when it has risen back to normal levels.
1-123
Evidence Against Market Efficiency Excessive Volatility: the stock market
appears to display excessive volatility; that is, fluctuations in stock prices may be much greater than is warranted by fluctuations in their fundamental value.
المفرط التباين ظاهرة Researchers have found that fluctuations in the S&P
500 stock index could not be justified by the subsequent fluctuations in the dividends of the stocks making up this index.
Other research finds that there are smaller fluctuations in stock prices when stock markets are closed, has produced a consensus that stock market prices appear to be driven by factors other than fundamentals.
1-124
Evidence Against Market Efficiency Mean Reversion: Some researchers have
found that stocks with low returns today tend to have high returns in the future, and vice versa.
الربح معدل الى الرجوع ظاهرة Hence stocks that have done poorly in the
past are more likely to do well in the future because mean reversion indicates that there will be a predictable positive change in the future price, suggesting that stock prices are not a random walk.
Newer data is less conclusive; nevertheless, mean reversion remains controversial.

Evidence Against Market Efficiency New Information Is Not Always
Immediately Incorporated into Stock Prices
المعلومًات مع التجًاوب في السوق تأخر ظًاهرةالجديدة
Although generally true, recent evidence suggests that, inconsistent with the efficient market hypothesis, stock prices do not instantaneously adjust to profit announcements.
Instead, on average stock prices continue to rise for some time after the announcement of unexpectedly high profits, and they continue to fall after surprisingly low profit announcements.
