Arbitrage Concentrates In Only A Few Markets ? Source: Shliefer and Vishny (1997) What would you get if you converted: Arbitrage is concentrated in bonds and exchanges and little in stocks There is low cost and risk There is high leverage
Arbitrage Doesn’t Necessarily Correct Mispricing Source: Brunnermeier, and Nagel (2004) Professionals made big profits off the internet bubble – buying and selling at the right time Everyone believed the prices were too high – but forecasted even higher prices in the future
Behavioral Effects Can Be Hard To Arbitrage Source: Benartzi and Thaler (1995) • Stocks have outperformed bonds over the last century by too high a margin • Myopic loss aversion • Investors are very sensitive to losses, and even long-term investors focus on short-term losses, hence demanding a very high equity premium • How would you arbitrage myopic loss aversion?
Long Term Capital Management Source: Lowenstein (2001) Arbitraged similar bonds (30 yr & 29.5 yr) and figured they would converge in the long run Annual returns were > 40%! Lost $4.6B over 4 mos in 1998 Eventually, the bond prices did converge but LTCM went bankrupt waiting

Causes Of Under-Reaction Source: Fuller (2008) • Anchoring • Individuals are tied to their previous opinions, causing under-reaction to new information, resulting in biased expectations • Overconfidence • Individuals place too much confidence in existing knowledge, causing under-reaction to new information
Analysts Under-React to Earnings Surprises Analysts are surprised again and again when growing companies outperform forecasts Surprises are greater when earnings increases are permanent (i.e., success of a new product) versus temporary (i.e., change in exchange rate)

Causes Of Over-Reaction Source: Fuller (2008) • Representativeness • People tend to infer that a single observation represents the entire population (stereotyping) • Saliency • People tend to over-estimate the probability of a low frequency event (earthquakes) • Prospect Theory • Investors may be irrationally risk averse in the domain of losses

Disclosure Statement Fuller & Thaler Asset Management, Inc. claims compliance with the Global Investment Performance Standards (GIPS®). Fuller & Thaler has been verified for the period from January 1, 1992 through March 31, 2008 by Beacon Verification Services, LLC. A copy of the verification report is available upon request. This information is provided solely for general informational purposes and does not constitute an offer to sell or a solicitation of an offer to buy or sell any product or service to any person or in any jurisdiction where such offer or solicitation would be unlawful. Fuller & Thaler is an independent investment management firm registered with the U.S. Securities and Exchange Commission that manages primarily equity assets for primarily institutional investors. Fuller & Thaler seeks to identify mis-priced securities by exploiting insights from the field of behavioral finance. The firm changed its name from RJF Asset Management, Inc. to Fuller & Thaler on December 14, 1998. The firm was called RJF Asset Management, Inc. as of April 5, 1993 to December 13, 1998. The investment philosophy has remained constant throughout the firm’s history. *Assets in a composite may exclude accounts in a strategy that do not comply with the composite’s account inclusion criteria. Market Neutral Composite is primarily invested in the equities of the top 1,500 U.S. companies ranked by market capitalization and liquidity. The composite has a $10 million account minimum and was created in February 2000. The composite is an un-levered version of the market neutral strategy which employs a long/short strategy managed with minimal net dollar exposure and minimal net beta exposure and is measured against the Citigroup BIG Treasury Bill (3 M) (LOC) Index. The standard advisory fee is a 1.0% per annum management fee and a performance fee of 20% of the profits in excess of a T-Bill hurdle subject to a “high water mark.” For the period February 1, 2000 through April 30, 2000 the composite returns represent the performance for the long and short equities carved-out of a market neutral account passively equitized with S&P 500 futures (S&P 500 futures were purchased and "rolled" on a quarterly basis to maintain a passive exposure to the S&P 500 index). The composite returns were derived by excluding the futures positions from this equitized market neutral account. The carve-out received a 100% cash allocation.
