Working Papers

·      Di Maggio M., Franzoni F., Massa M., Tubaldi R. (2019), Strategic Trading as a Response to Short Sellers

Abstract:

We study empirically informed traders’ reaction to the presence of short sellers in the market. We find that investors with positive views on a stock strategically slow down their trades when short sellers are present in the same stock. Moreover, they purchase larger amounts to take advantage of the price decline induced by short sellers. Furthermore, they break up their buy trades across multiple brokers, suggesting that they wish to hide from the short sellers. This behavior may impact price discovery, as we find a sizeable reduction of positive information impounding for stocks more exposed to short selling during information sensitive periods. The evidence is confirmed exploiting exogenous variation in short interest provided by the Reg SHO Pilot Program. The findings have relevance for the regulatory debate on the market impact of short selling.

·      Di Maggio M., Egan M., Franzoni F. (2018), The Value of Intermediation in the Stock Market

Abstract:

Abstract Brokers continue to play a critical role in intermediating stock market transactions for institutional investors. More than half of all institutional investor order flow is still executed by high-touch (non-electronic) brokers. Despite the importance of brokers, we have limited information on what drives investors' choices among brokers. We develop an empirical model of intermediary choice to investigate how institutional investors trade across different brokers. We analyze investors' responsiveness to the commissions paid, the broker's ability to efficiently execute the trades, as well as access to better research analysts and order flow information. We find that investors are relatively insensitive to commissions, but on average value research, execution, and access to information. Furthermore, using trader-level data we find that investors are more likely to trade with brokers who are physically located closer and are less likely to trade with brokers whose traders have misbehaved in the past. There is also significant heterogeneity across investors, with the best performing investors placing a higher value on order flow information and less value on research. We use the model to analyze several counterfactuals highlighting key inefficiencies in the market that raise trading costs.

NBER Working Paper No. 22247

Stigler Center Pro-Market Blog Post

Abstract:

Over last 35 years institutional ownership became concentrated at unprecedented levels; e.g., the stock holdings by the largest ten asset management firms quadrupled from 5.6% to 23.1%. Due to their sheer size, institution-level shocks cannot be diversified away and can spill over to the underlying securities. We document that stock ownership by the largest institutional investors leads to an increase in the volatility of the assets that they hold. Furthermore, stocks held by the largest institutional investors exhibit patterns of price inefficiency. We show that these effects are triggered by institution-level idiosyncratic news and channeled through large trades.

Winner of the Inquire Europe Research Grant in 2012

Online Appendix

Abstract:

The paper investigates the determinants of limits of arbitrage for liquidity providers. Using data on institutional transactions, we compare hedge fund trades to those of other institutions. We find that hedge funds’ liquidity provision is more exposed to financial conditions than that of other institutions. We identify leverage, low redemptions restrictions, asset illiquidity, and reputational capital as a relevant set of characteristics that explain the exposure of hedge funds’ liquidity supply to funding conditions. Finally, we find that the trades of financially constrained hedge funds underperform for at least one quarter following negative funding shocks.

·         Franzoni F. (2008), The changing nature of market risk

Abstract:

In the first three decades of CRSP data, value stocks have higher betas than growth stocks. Later on, the ranking is reversed and the gap in beta widens. What makes growth strategies nowadays bear more market risk than value strategies? What are the causes of the reversal in the ranking of betas? The paper argues that the negative link between beta and BM is due to growth options. The shift of listed firms towards more growth-oriented businesses has progressively changed the nature of market risk. The ultimate determinant of this evolution is conjectured to be financial market development, which has lowered the cost of capital. For this reason, the facts described in this paper resonate with other long-run phenomena, such as the rise in idiosyncratic risk and the R&D boom.

·         Franzoni F. (2002), Where is beta going? The riskiness of value and small stocks (cite as: Ph.d. Thesis, Massachusetts Institute of Technology)

Abstract:

This paper finds that the market betas of value and small stocks have decreased by about 75% in the second half of the twentieth century. The path of beta can be closely tracked using variables that summarize the state of the economy. On the basis of this analysis, the decline in beta can be related to a long-term improvement in economic conditions that made these companies less risky. Decomposing beta into the cash flow and expected return news components confirms that the payoffs of these companies are less sensitive to market conditions. This finding has implications for the debate on the CAPM anomalies.
