OVERVIEW OF TALK

Understanding market efficiency and asset pricing

– How do you beat the efficiently inefficient market?

– Investment styles and strategies

Equilibrium model and asset prices and asset management

– Efficiency of asset market linked to efficiency of asset management

Market efficiency: at the heart of financial economics

Nobel Prize 2013 awarded to Eugene Fama, Lars Hansen, and Robert Shiller

MARKET EFFICIENCY

Efficient! Inefficient!

Page 4: Copenhagen Business School, NYU, CEPR, AQR … Business School, NYU, CEPR, AQR Capital Management OVERVIEW OF TALK Understanding market efficiency and asset pricing – How do you

EFFICIENT MARKETS?

Markets cannot be fully efficient

If they were, no one would have an incentive to collect information (Grossman-Stiglitz, 1980)

Logically impossible that both market for asset management and asset markets fully efficient

– Asset market efficient no one should pay for active management

Clear evidence against market efficiency

– Failure of the Law of One Price, e.g.

– Siamese twin stock spreads

– Covered Interest-rate Parity

– CDS-bond basis

– not subject to joint hypothesis problem

INEFFICIENT MARKETS?

Markets cannot be completely inefficient

Money managers compete to buy low and sell high

Free entry of managers and capital

If markets were completely inefficient

– Making money should be very easy

– But, professional managers hardly beat the market on average

EFFICIENTLY INEFFICIENT MARKETS

Markets are efficiently inefficient

Markets must be

– inefficient enough that active investors are compensated for their costs

– efficient enough to discourage additional active investing

Investment implications

– Some people must be able to beat the market

– at least before transaction costs and fees

– but even after costs, though, of course, less so

IS THE WORLD EFFICIENTLY INEFFICIENT ?

Competition + frictions = efficiently inefficient dynamics

Efficiently inefficient traffic dynamics

Efficiently inefficient political process

Efficiently inefficient nature: evolution has not converged yet

Questions:

How do you beat the market when it is efficiently inefficient?

What are the equilibrium

– prices

– efficiency

– asset management fees

– number and size of managers?

HOW DO YOU BEAT THE MARKET?

Page 10: Copenhagen Business School, NYU, CEPR, AQR … Business School, NYU, CEPR, AQR Capital Management OVERVIEW OF TALK Understanding market efficiency and asset pricing – How do you

HOW DO YOU BEAT THE MARKET? LIQUIDITY PROVISION

How do you make money in any business?

– E.g., consider a burger bar:

– Customers are willing to pay more for a burger than the value of meat+bun+salad

– Burger bars make profits for proving a service, but free entry ensures that profits are efficiently inefficient

How do you make money investing?

– Institutional frictions make certain investors “demand liquidity”

– Active money managers provide liquidity by taking the other side

– Free entry drives the price of liquidity to its efficiently inefficient level

– Reflects risk, operational costs, transaction costs, funding costs

Liquidity

1000s of hedge funds and active mutual funds

– across different markets, continents, asset classes, …

But, can we summarize the main trading strategies through a few investment styles?

– method that can be applied across markets

– based on economics

– broad long-term evidence

HOW DO YOU BEAT THE MARKET? INVESTMENT STYLES

Investment styles

Liquidity provision

Value investing

Trend-following

Carry trading

Low-risk investing

Quality investing

Buffett’s performance

Page 13: Copenhagen Business School, NYU, CEPR, AQR … Business School, NYU, CEPR, AQR Capital Management OVERVIEW OF TALK Understanding market efficiency and asset pricing – How do you

INVESTMENT STYLES: VALUE AND MOMENTUM EVERYWHERE

Asness: we’re looking for cheap stocks that are getting better, the academic ideas of

value and momentum

Ainsley: sustainable free cash flows in comparison to enterprise value… it’s certainly

important to be attuned to short-term expectations as well

Chanos: we to try short overvalued firms… if a position is going against us, we’ll trim

it back

Soros: I look for boom-bust cycles

Harding: trends are what you’re looking for

Scholes: most of the fixed income business is a negative-feedback-type business unless

you're directional, which is positive feedback, or trend following

Griffin: view markets through the lens of relative value trading

Paulson: the target stock runs up close to the offer price but trades at a discount to the

offer price because of the risks of deal completion

EFFICIENTLY INEFFICIENT MARKETS FOR ASSET AND ASSET MANAGEMENT

Making asset prices relatively efficient is costly

Market for asset management arises naturally

– Economies of scale in sharing information costs

Asset management markets may also be inefficient

This paper:

– Asset management efficiency ↔ asset market efficiency

– Testable implications for

– asset prices

– asset management fees

– performance of asset manager

– size and number of asset managers

– market liquidity

GENERAL EQUILIBRIUM FOR ASSETS AND ASSET MANAGEMENT

Page 24: Copenhagen Business School, NYU, CEPR, AQR … Business School, NYU, CEPR, AQR Capital Management OVERVIEW OF TALK Understanding market efficiency and asset pricing – How do you

Proposition.

In equilibrium, asset managers outperform passive investing before and after fees.

In an interior equilibrium, active investors' outperformance net of fees just

compensates their search costs

so larger search frictions means higher net outperformance.

i. Efficiently inefficient markets

– Anomalies more likely to arise with higher c or k

ii. Asset managers performance

– managers can outperform before fees: Grinblatt and Titman (89), Wermers (00), Kacperczyk,

Sialm, and Zheng (08), Kosowski, Timmermann, Wermers, and White (06)

– average mutual fund may underperform after fees due to noise allocators: Carhart (97), Berk

and Binsbergen (12)

– but the best mutual funds outperform even after fees: Kosowski et al (06), Fama and French (10)

– hedge funds may outperform after fees: Kosowski, Naik, and Teo (07), Fung, Hsieh, Naik, and

Ramadorai (08), Jagannathan, Malakhov, and Novikov (10) – fewer noise allocators?

– private equity and venture capital performance persistence: Kaplan and Schoar (05); Raise

money contingent on reaching a total amount

– performance slightly predictable, especially in HF/PE markets where search costs are larger

iii. Lower search frictions, flows to asset managers

– Sirri and Tufano (98), Jain and Wu (00), and Hortacsu and Syverson (04)

– Growth of asset management industry: French (08)

EMPIRICAL IMPLICATIONS

Page 29: Copenhagen Business School, NYU, CEPR, AQR … Business School, NYU, CEPR, AQR Capital Management OVERVIEW OF TALK Understanding market efficiency and asset pricing – How do you

iv. Asset management fees

– should be larger for more inefficient assets due to larger information or search costs

– HFs vs. mutual funds, equity funds vs. bond funds, global equity vs. domestic equity

v. Size and organization of asset-management industry

– total size grows when c or k diminish: Pastor, Stambaugh, and Taylor (14)

– industry consolidates when c goes down

– good managers attract more investors (Berk and Binsbergen 12)

vi. Investment consultants, investment advisors, funds of funds

– Fund of Funds (non-noise allocators) should be able to predict manager perf.: Ang, Rhodes-Kropf,

and Zhao (08)

EMPIRICAL IMPLICATIONS, CONTINUED

CONCLUSION: EFFICIENTLY INEFFICIENT ECONOMICS
