Research Questions: • How large are trading costs faced by large arbitrageurs? • How robust are anomalies in the literature after realistic trading costs? • At what size do trading costs start to constrain arbitrage capital? • What happens if we take transactions costs into account ex ante? – Tradeoff between expected returns and trading costs varies across anomalies Trading Costs of Asset Pricing Anomalies - Frazzini, Israel, and Moskowitz 2 Objectives Measure trading costs of an ―arbitrageur‖ Understand the cross-section of net returns on anomalies Model of trading costs for descriptive and prescriptive purposes Constructing optimized portfolios Conclusion Trading Costs of Asset Pricing Anomalies - Frazzini, Israel, and Moskowitz 3 What We Do Take all (longer-term) equity orders and executions from AQR Capital • 1998 to 2013, $1.1 trillion worth of trades, traded using automated algorithms • U.S. (NYSE and NASDAQ) and 18 international markets— • *Exclude ―high frequency‖ (intra-day) trades Use actual trade sizes and prices to calculate • Price impact and implementation shortfall (e.g., Perold (1988)) More accurate picture of real-world transactions costs and tradeoffs • Get vastly different measures than the literature • Actual costs are 1/10 the size of those estimated in the literature • Why? 1) Average trading cost ≠ cost facing an arbitrageur 2) Design portfolios that endogenously respond to expected trading costs Trading Costs of Asset Pricing Anomalies - Frazzini, Israel, and Moskowitz 4 Measuring Trading Costs Literature has used a variety of models and types of data to approximate trading costs: • Daily spread and volume data [Roll (1984), Huang and Stoll (1996), Chordia, Roll, and Subrahmanyam (2000), Amihud (2002), Acharya and Pedersen (2005), Pastor and Stambaugh (2003), Watanabe and Watanabe (2006), Fujimoto (2003), Korajczyk and Sadka (2008), Hasbrouck (2009), and Bekaert, Harvey, and Lundblad (2007)] • Transaction-level data (TAQ, Rule 605, broker) [Hasbrouck (1991a, 1991b), Huberman and Stanzl (2000), Breen, Hodrick, and Korajczyk (2002), Loeb (1983), Keim and Madhavan (1996), Knez and Ready (1996), Goyenko (2006), Sadka (2006), Holden (2009), Goyenko, Holden, and Trzcinka (2009), Lesmond, Ogden, and Trzcinka (1999), Lesmond (2005), Lehmann (2003), Werner (2003), Hasbrouck (2009), and Goyenko, Holden, and Trzcinka (2009)] • Proprietary broker data [Keim (1995), Keim and Madhavan (1997), Engle, Ferstenberg, and Russell (2008)] Several papers have applied trading cost models to anomalies, chiefly size, value, and momentum. Most find costs are significantly binding. • Chen, Stanzl, and Watanabe (2002) • Korajczyk and Sadka (2004) • Lesmond, Schill, and Zhou (2003) Trading Costs of Asset Pricing Anomalies - Frazzini, Israel, and Moskowitz 5 Trading Execution Database Trade execution database from AQR Capital Management • Institutional investor, around 118 billion USD in assets (October 2014) • Data compiled by the execution desk and covers all trades executed algorithmically in any of the firm’s funds since inception (*excluding stat arb trades) Information on orders, execution prices and quantities • Common stocks only: restrict to cash equity and equity swaps • 19 Developed markets (drop emerging markets trades) • Drop liqudity/statistical arbitrage trades • Result: ~9,300 global stocks , 1.1 trillion USD worth of trades Price, return and volume data • Union of the CRSP tapes and the XpressFeed Global database Trading Costs of Asset Pricing Anomalies - Frazzini, Israel, and Moskowitz 6 Trade Execution Database This picture shows our trade execution database. • Last year’s data, the rest is in some nuclear-disaster-proof bunkers around the world • Frazzini almost froze to death to take this photograph Trading Costs of Asset Pricing Anomalies - Frazzini, Israel, and Moskowitz 7 Trade Execution Data, 1998 – 2013.

How exogenous are trading costs to the portfolios being traded by our manager? Trading costs we estimate are fairly independent from the portfolios being traded. 1. Only examine live trades of longer-term strategies, where portfolio formation process is separate from the trading process executing it. 2. Set of intended trades is primarily created from specific client mandates that often adhere to a benchmark subject to a tracking error constraint of a few percent. 3. Manager uses proprietary trading algorithms, but algorithms cannot make any buy or sell decisions. Only determine duration of trade (1-3 days). 4. Exclude all high frequency trading. We also examine only the first trade from new inflows.
