Chapter: One – Introduction
1.1 Introduction to the Study
Nowadays People are talking on the subject of Share Market and ‘Going Public’ by
private companies. Especially in Sri Lanka, the topic has been given a considerable value
as Sri Lankan Share Market is considered as one of the fastest growing share markets in
today’s world. As a result of this, so many private companies are planning and already
made the ground work for making their IPO for “Going Public”. Even though with this
booming trends almost all the big companies are planning to go public, the main thing
what they have to investigate is that why the Initial Public Offerings are underpriced in
significant percentage.
The under pricing of initial public offering (IPOs) is a well-documented experience in
stock markets around the world. The short-run or initial return, measured as the
difference between the closing price on the first day of trading and the offer price, has
been estimated at an average of 17 % in the United States and at 27% in international
markets (Loughran et al, 1994 (2008 update)).
Here I am going to study and investigate the initial under pricing of IPOs in the Colombo
Stock Exchange (CSE) of Sri Lanka from 1990 to 2009. The sample includes 107 IPOs
consisting for both conventional and privatization issues.
My study on IPO under pricing will be basically focusing the following major steps.
01. This study is focused to examine the distribution of first- day under pricing by
issue year and industry.
02. Performing a univariate analysis of under pricing by small vs. large issues,
investor sentiment, and conventional vs. privatization issues.
- 5 -
03. Examining the ability of the size of the offer, investor sentiment, privatization,
hot market conditions, underwriter size, and industries to singly and jointly
explain the cross – sectional variability of under pricing using regression models.
04. This study assesses the ability of investor sentiment and privatization to explain
the difference in under pricing between small and large issues.
1.2 Problem Statement What are the reasons for under pricing of IPOs? Why smaller issues are more
underpriced than large issues? Are investors sentiments positively related with the IPO
under pricing? Why Privatization IPOs are more underpriced than conventional IPOs?
1.3 Problem Justification
There are several reasons for IPO under pricing and we have to identify those main
reasons for achieving a conclusion
As with previous work in other markets, the univariate results show that small issues
are more under priced, investor sentiment is positively related with under pricing, and
privatization issues are more under priced. Issue size, a measured by gross proceeds
from the issue, is reliably negatively related with under pricing, and small issues are
more under priced than large issues by about 37 %. Investor sentiment, as substitute by
market returns in the three –month period prior to the first day of trading, is positively
related with under pricing. Privatization issues are more under priced than
conventional issues by a large 49 %.

1.4 Significance
This study will be really giving a value addition to the existing investors, potential
investors who are very keen on investing initial public offerings, Private companies
which are planning to “Going Public” in near future, Students who are really interesting
about the share market situations for their researches and projects etc.
1) Private Companies who planning to “Going Public”
By using this analysis, they will have a very clear idea about the reasons for
under pricing and all the related issues to be faced and how to overcome
these issues when they doing their IPO.
2) The Potential investors on IPOs
They will be able to analyze critically what is happening when investing in
IPOs and what is the relationship between the long term performance and
short term IPO under pricing. And also how it will affect to the share value of
what he has already purchased.
3) Students who are interested about share market phenomenon and the
behavior of the share market and the pricing of shares and valuations.
4) This study will help to General Public who are willing to obtain the general
knowledge about the share market of Sri Lanka.
5) In addition to the above mentioned factors, this study will also help
any new researchers that will be carrying out further research on the topic to
be used as a base paper in the future studies.

1.5 Objectives
2. To find out the under pricing percentage of Initial Public Offerings in Sri Lanka.
3. To find out the relationship between small issues and large issues in relation to
IPO under pricing.
4. To investigate the relationship between Privatization issues and conventional
issues relating to IPO under pricing in Sri Lankan context.
5. To identify the relationship between investor sentiment (emotion) and IPO
under pricing in Sri Lankan context.
1.6 Scope of the Study
This study investigates underpricing of IPOs in Sri Lanka. The study basically focus on
the reasons for IPO underpricing and the relationship with various phenomenon which
are directly and indirectly having positive and negative relationships with the
underpricing of IPOs. In addition to that, the study is focusing on the previous studies
have been carried out on the topic and the validity of those studies when comes to Sri
Lankan context.
Chapter: Two – Literature Review
Stock trading in Sri Lanka began in 1896. The Sri Lankan stock market, in its present
form, was established in 1984 with the formation of the Colombo Stock Exchange (CSE).
As of the end of 2008, the CSE had 235 listed companies, and a total market
capitalization of the 489 billion rupees ($4.3 billion). During its 24 year history
from 1985- 2008, the stock market produced a historical average annual return
(excluding dividends) of 18.4 %, and an equity risk premium 3.6 % in local currency
terms. The stock market was liberalized for foreign investors in June 1990. The capital
gains tax was abolished in 1992, and there is no tax on capital gains for either foreign or
- 8 -
local investors. The Securities and Exchange Commission of Sri Lanka, which was
established in 1987, regulates the market. Insider trading is prohibited in Sri Lanka.
There are 15 stock brokering companies in the market. The Sri Lankan stock market is
not a dealership market. Brokers act as intermediaries to transactions, and do not
engage in market making. Trading of securities in the Colombo Stock Exchange is
completely automated, and the CSE is considered one of the finest trading systems in
the world. The automated trading system was introduced in June 1997. Brokers are
electronically connected to a central computer, located at the CSE, which automatically
executes orders on the basis of price-time priority. The settlement period is t+ 5 for buy
and t+ 6 for sell transaction, where t is date of the trade. Transaction cost is 1.125 % for
transactions up to 1 million rupees and 1.025 % for transactions exceeding that amount.
Trading takes place on weekdays, except exchange holidays, from 9:30 A.M. to 12.30
P.M.
A company can be listed in the Colombo Stock Exchange in one of three ways, namely,
offer for subscription, offer for sale, or introduction. An offer of subscription is an offer
by an issuer to sell its own shares to the public. This involves the sale of new shares and
the issuer raises capital through the sale. This is by for the most widely used method for
IPOs in Sri Lanka. An offer for sale is an offer to sell shares held by the existing
shareholders to the public. This method has been used primarily in privatization of
public enterprises by the government to sell its shares of state-owned enterprises to the
public. An introduction is the listing of already existing shares of a company without
making a public issue. This method of listing began in 2000, and since than 15
companies has been listed by way of introduction.
The companies in Sri Lanka are allowed to use fixed-price, auction, as well as book
building methods for IPOs. However, all the IPOs have used the fixed-price method,
except two recent issues which have used the Dutch auction method.
Although underwriting as issue is not mandatory, the practice is to have the issues
underwritten by an investment bank. The issuer is required to obtain the services of a
- 9 -
sponsoring firm registered with the CSE. These sponsors are generally the merchant
and investments banks. The role of the sponsor is to ensure that the share issue
complies with the stock exchange and other regulatory requirements relating to the IPO.
Any investor can subscribe for shares by submitting a completed subscription
application along with a check for the total value of the shares subscribed. An
application can be submitted through any of the 15 registered stock brokering firms.
Except in rare circumstance, such as in privatization IPOs where certain limits to the
number of shares per applicant may be specified, an investor can apply for any number
of shares.
The existing literature shows that small issues are more under priced than large issues
(Ritter, 1984; Beatty and Ritter, 1986), investor sentiment is positively related with
under pricing (Ritter, 1984), and privatization IPOs are more under priced than
conventional IPOs (Jones et al, 1999; Perotti and Guney, 1998).
2.1 Short-run under pricing in emerging markets
Since the present study is based on the emerging stock market of Sri Lanka, previous
evidence on IPO under pricing from emerging markets is particularly relevant. Previous
studies show that initial under pricing is a common phenomenon in markets around the
world. However, there is a great deal of variability in under pricing across markets and
regions. In terms of initial returns in the Asian region, Islam (1999) finds 116 % in
Bangladesh, Chen et al. (2004) report 145 % in China, and Marisetty and Subramanyam
(2005) show 94 % in India. Boulton et al. (2007) show evidence of under pricing for
Indonesia (41%), Malaysia (41 %), South Korea (44 %) , Taiwan (13 %), and
Thailand(26 %). Further, Amihud et a. (2002) reports under pricing of 12 % in Israel,
and Sullivan et al. (1999) finds 23% initial returns in Philippines. Thus, Sri Lanka’s
neighbor india has experienced a very high degree of under pricing. The markets in the
Asia have shown a much larger degree of under pricing than markets in any other
region, largely due to very high under pricing in Bangladesh, China and India.
2.2 Explanations for the short-run under pricing
- 10 -
The present study investigates the cross sectional variation in IPO under pricing by
issue size, investor sentiment, issue type (conventional and privatization issues), and
the issuer’s industry. This section discusses the existing literature and testable
implications related to issue size, sentiment, privatization, and industry.
2.2.1. Under Pricing and issue size
Beatty and Ritter (1986), based on the asymmetric information model of Rock (1986),
present a model in which greater the ex-ante uncertainty about the value of the issue,
the greater the expected under pricing. The theory predicts a direct relation between
ex-ante uncertainty and under pricing. Beatty and Ritter (1986) use gross proceeds as
one of the proxies to capture ex-ante uncertainty because small issues are considered
more risky than large offerings. Consistent with the theory, they find that the inverse of
gross proceeds is significantly positively related with under pricing. High-risk IPOs
should be more underpriced than low-risk issues. Using sales in the 12-month period
prior to the IPO as a proxy for risk, Ritter (1984) finds that higher-risk (lower sales)
issues have higher average initial returns than lower-risk (higher sales) issues. Issue
size has been used as a proxy for ex-ante uncertainty in other studies as well (e.g.,
Amihud at al., 2002; Kiymaz,200; Ljungqvist, 1997). The testable implication of the ex-
ante uncertainty hypothesis is that the smaller the issue size, the larger will be the
initial under pricing. This study tests this implication using gross proceeds as a proxy
for ex-ante uncertainty about the value.
2.2.2. Under pricing and investor sentiment
Another potential factor influencing under pricing is the investor sentiment before the
first day of trading of an IPO. Ritter (1984) calls this the institutional lag hypothesis
because of the time gap between when the offer price is determined and the new issue
is traded. Investor sentiment is defined as the general attitude of investors in the
aggregate about the short-term direction of the overall market. Positive sentiment,
which investors expect the overall market to trend upward, is likely to increase the
demand for the IPO stocks on the first day of trading resulting in price appreciation.
Similarly, negative sentiment, which shows that investors expect the overall market to
- 11 -
decline in the short-term, is likely to diminish the enthusiasm for the IPO on the first
day of trading. Thus, investor sentiment and under pricing is expected to be positively
related.
Ritter (1984) uses returns on the natural resources index from the registration date to
the offering date as a proxy for institutional lag to investigate high under pricing in
natural resource IPOs. Investor sentiment can also be measured using the market return
for a defined period prior to the first day of trading (e.g., Amihud et al., 2002, Kiymaz,
2000; Ljungqvist, 1997; Kunz and Aggrarwa, 1994). This study tests the implication of
the investor sentiment hypothesis using cumulative market returns for the three-month
period preceding the first day of trading as a proxy for investor sentiment regarding the
direction of the market.
2.2.3. Under pricing and privatization
Privatization IPOs can be considered more risky than conventional IPOs, and therefore
contain more ex-ante uncertainty. This higher uncertainty regarding the value of
privatization IPOs can be attributed to several factors. Perotti (1995) argues that
privatizations are associated with considerable policy uncertainty after the
privatization. Governments may yield to pressure by stake holders to reallocate value
through policy changes such as re-regulation, taxation, changes in regulated rates, and
entry deregulation etc. Hence, government may signal the commitment to a future
policy by under pricing the issue. Privatization IPOs may contain a higher risk premium
due to their greater exposure to political risk (Huibers and Perotti, 1998). These and
other factors may cause more ex-ante uncertainty about the true value of privatization
IPOs relative to conventional IPOs leading to more under pricing of privatization IPOs.
Indeed, previous studies show that for many countries the average initial under pricing
of privatization IPOs is much higher. For example, in a study of share-issue
privatizations, Jones et al. (1999) show that initial under pricing is 34.1 % for initial
offers and 9.4 % for seasoned offers. Others show that under pricing in privatization
issues is higher than that in non-privatization issues (e.g., Perotti and Guney, 1993;
Dewenter and Malatesta, 1997; Jenkinson and mayer, 1988). Huibers and Perotti (1998)
show that privatization stocks in emerging markets exhibit greater exposure to political
- 12 -
risk, and superior post-IPO performance of privatization stocks reflects in part the
progressive resolution of this political risk. Hence, in this study, it is hypothesized that
privatization issues will be more underpriced than conventional issues due to the
increased ex-ante risk in the spirit of the ex-ante uncertainty hypothesis.
2.2.4. Under pricing and Industry
There is also evidence of industry effects in IPO under pricing Ritter (1984), for
example, finds that the hot issue market of 1980 in the U.S. is entirely attributable to
under pricing in the natural resources industry. Evidence on industry clustering has
been found in other work as well. Stocks in Sri Lanka are classified in to 20 industries,
and privatization issues have been particularly shown to be concentrated in some
industries such as footwear and textiles, Plantations, and manufacturing. Hence, it is
reasonable to suspect the presence of industry effects in under pricing. Therefore, this
study investigates the initial returns across the industry categories to detect any
industry effects of under pricing.

Chapter: Three – Research Methodology
This research will be carried out after analyzing all the related theoretical background
on the topic. For the research to be well performed, I already have created certain
hypothesis in relation to the IPO under pricing. The study has to be carried through
Deductive Reasoning method as the research has been involved with so many
hypothesis testing.
The short-run performance of IPOs is measured by the initial return calculated as the
difference between the first-day closing price and the offer price as a percent of the offer
price.
This can be explained as follows.
First-Day Closing Price – Offer Price 100
Initial Return =
Offer Price
To study the time-series and cross sectional patterns of initial performance of IPOs, this will
be examined equally-weighted initial returns by
(1) Issuer year
(2) Issuer’s industry
(3) Issue size
(4) Investor sentiment
(5) Privatization vs. conventional issues.
The differences in average initial returns between categories have to be tested using the
two-sample t-test allowing for unequal variances. Then, the relation between the initial
- 16 -
returns and size, sentiment, privatization, and industry has to be investigated through a
multivariate cross-sectional regression models. The motivation for the regression analysis
is to provide a test of the ability of these factors to jointly explain the cross sectional
variation in initial IPO returns in Sri Lanka.
The effect of the issue size on initial return will be captured through size, which is the
natural logarithm of proceeds of the issue.
It is important to capture any industry effects on initial returns. To incorporate industry
effects, the regression models will have to be modified with certain industry categories. T-
statistics will be used to assess the statistical significance of the coefficients.
In order to investigate the impact of the investor sentiment on small vs. large issues the
initial returns will have to be further classified by sentiment and size. In this analysis,
sentiment is classified as either positive or negative. Market conditions in which the
cumulative market returns over the three – month period preceding the first-trading day
are greater than zero will be used to proxy for positive market sentiment. Accordingly,
sentiment will be defined as a dummy variable which takes the value of 1 if the sentiment is
positive is positive and 0 if the sentiment is negative.
Further, to examine the impact of privatization on small vs. large issues, initial returns will
have to be categorized by privatization and size. This classification is used to assess if any
size-effect is attributable to a privatization –effect, and there by provide clarity to the
uncertainty hypothesis.
3.1 Research Strategy
This research is basically a quantitative research and so some of the quantitative
research strategies will have to be used for reaching a justifiable conclusion. As a result
of this, empirical study will be carried out with some of the quantitative techniques such
as Regression Analysis, Student-t distribution etc.

3.2 Population
There are 238 companies have been listed in Colombo Stock Exchange from 1987 to
2009. The data on Sri Lankan IPOs were obtained from the Colombo Stock Exchange,
and the Securities and Exchange Commission of Sri Lanka. The data include the name,
industry, offer price, the number of shares offered, name of the underwriter, first date of
trading and the first-day closing price in respect of all new issues of shares that took
place in the 22-years period from 1987 to 2009.
3.3 Sampling
When selecting the sampling technique for selecting the justifiable sample, following
factors have been considered.
IPOs of non-voting common stocks and preferred stocks are excluded. The study also
excludes the listings made through introductions, since they do not have an offer price.
The total number of IPOs of voting common stocks is 118.
For the purpose of the study, IPOs with the issue size greater than 900 million rupees
and initial returns greater than 300 % are considered outliers, and hence excluded from
the sample.
After considering all the above exclusions, the final sample selected is 107 IPO issues
from 1987 to 2009.
The performance of the overall market is measured by the All Share Price Index (ASPI)
of the CSE, which is a value-weighted price index (excluding dividends) of all listed
stocks. The sample includes 30 privatization IPOs and conventional or non-privatization
issues.

3.5 Operationalization of Variables
Regression Analysis and Correlation Coefficient technique have been widely used in
previous studies by the several Researchers who already investigated the issues
relating to Initial Public Offerings. So the same methods will be used in this research as
well.
Primary data will be obtained by having face to face interviews with share market
professionals and the experts in the field. In addition to that, secondary data will be
obtained from the books, CDs and annual reports published by the Colombo Stock
Exchange and Securities Exchange Commission of Sri Lanka.
Chapter: Four – Conclusion
As clearly mentioned in the Problem Statement, there are some IPO related anomalies
which are still not properly investigated especially in Sri Lankan context. Several studies
have been carried out in other countries and in the analysis of Literature review, it is clear
that the issues are exist in almost all the countries which are having Stock Exchanges.
