Master's Thesis from the year 2020 in the subject Economics - Finance, grade: 1,0, University of Vienna (Fakultät für Wirtschaftswissenschaften), language: English, abstract: This paper investigates the impact of short sale bans on the market microstructure of equity markets by focusing on three major stock market characteristics: (How) did the ban affect stock liquidity, (how) did the ban influence price efficiency, and did the regulators manage to stabilize stock prices by imposing short sale bans? On March 12, 2020, the EURO STOXX 50, the major European stock index declined by more than 12% - the largest loss ever reported on a single day since index inception in 1986. Other major stock indices around the globe experienced a similar drop. The Covid-19 crisis was about to hit and there was great uncertainty among investors, reflected by very volatile stock markets. The corresponding volatility index VSTOXX had its peak on March 16, 2020, with an implied volatility of 86%. To stabilize capital markets and restore the confidence of investors during volatile times, regulators can make use of temporary bans on short sales, i.e., restricting investors in their ability to profit from declining stock prices. This was the case in numerous countries during the financial crisis in 2007-09.

The short selling regulation of 2005 (regulation SHO), and its more restrictive version of 2008, was put in place to curb potentially manipulative naked short selling. However, this regulation has been criticized in the literature for reducing market quality. Contrary to other findings, I show that this regulation deters uninformed traders, and improves the informativeness of naked short sellers. In particular, after 2008, the aggregate naked short selling activity has increased in information content, and has become significantly connected to the percentage of net short positions in the E-Mini stock index futures markets. Consistent with the increased informativeness of naked short sellers, I find that the market views excessive and persistent naked short selling activity as a bearish signal only after 2008.

Book Description
This paper contributes empirical evidence to the debate on short sales. Our examination of how market-wide short-sale restrictions affect aggregate market returns focuses on two main questions: What is the effect of short-sale restrictions on skewness, volatility, the probability of market crashes, and liquidity? What is the effect on the market expected return or cost of capital? We report new data on the history of short-selling and put option trading regulations and practices from 111 countries, and create a short-selling feasibility indicator for empirical of stock market indices around the world. We find that when short-selling is possible, aggregate stock returns are less volatile and there is greater liquidity. When countries start to permit short-selling, aggregate stock price increases, implying a cost of capital. There is no evidence that short-sale restrictions affect either the level of skewness of returns or the probability of a market crash. Collectively, our empirical evidence shows that allowing short sales improves market quality.

Book Description
For many years, academics generally viewed uptick rules as short sale constraints that contribute to stock overvaluation and hamper stock price efficiency. Recently adopted Regulation SHO provides us with a natural experiment to study the impact of the suspension of uptick rules on various market quality measures in a controlled environment. In the first essay, I investigate the impact of removing short sale price test rules on stock returns and find that on the NYSE, removing the tick-test rule mitigates stock overvaluation. On the NASDAQ, however, lifting the bid-test rule goes beyond correcting such overvaluation. It shows that prices of high-dispersion stocks tend to be depressed relative to prices of low-dispersion stocks. I also examine the relationship between daily short selling activities and stock returns and find that on average short sellers are more likely to be value-driven "contrarians" who short sell following high stocks returns. In the second essay, I examine the information content of short selling around the release of analyst recommendations. By looking at the magnitude and the speed of price response to analyst downgrade recommendations, I provide intra-day evidence supporting the documented assertion that suspension of the uptick rule helps improve stock price efficiency. For after-hour downgrades, pilot stocks respond quickly, with virtually all of the price response incorporated by the following open, while control stocks take an extra half hour after opening to fully reflect the new information. For downgrades that occur during normal trading hours, downgrade information is partially incorporated into pilot stock prices up to two hours before the recommendation is released, while control stocks take up to an hour and a half after the recommendation release to impound the information into stock price. Finally, short selling activities prior to the release of analyst recommendations indicate that short sellers capitalize on their private information associated with upcoming downgrades in the control sample, but such behavior seems to disappear in the pilot sample. I conjecture that, during the pilot program, short sellers were aware of the SEC's regulatory scrutiny of pilot stocks and thus avoided trading on their private information in those stocks.

Book Description
We use the 2008 short selling regulations to conduct the first test of Diamond and Verrecchia's (1987) counterintuitive prediction that short sale constraints can actually increase the information content of short sales. The emergency order made it difficult and costly for short sellers without strong broker relationships to borrow shares; borrowing fees increased by over 500%. Similarly, the short selling ban prohibited short selling in the spot market, but sophisticated traders could still short synthetically via the options market. As such, there is good reason to expect that both regulations increased the proportion of informed short sellers. Consistent with this notion, we find that the price reaction to announcements of unexpectedly high levels of short interest became more negative when the regulations were in effect. We also find that the price impact of short sales increased during the ban for affected stocks. Our results confirm the counterintuitive and previously untested prediction that short selling restrictions may actually increase the information content of short selling.

Book Description
This paper examines the effects of short sale deregulation on market quality by examining the implementation of regulation SHO, which removed the uptick rule for a subset of pilot securities. This created an exogenous event, allowing a direct examination of the effect of short sale constraints on the markets. This study builds on Roll and Subrahmanyam (2010) in examining the skewness of bid-ask spreads as they represent information asymmetry and market maker competition. We find that the price tests conducted in regulation SHO evenly effected both pilot and non-pilot securities, including a widening of bid-ask spreads and a decrease in spread skewness. These findings suggest that short sellers are shifting from liquidity demanders in the market to liquidity providers in the markets. This change is associated with positive effects in the price discovery process and overall market quality.

Book Description
Sebastian Werner examines aggregate short sales and convertible bond arbitrage, which is a typical hedge fund strategy that involves a significant short position in the underlying stock of a long convertible bond position for hedging purposes. He provides insightful and new observations of the significant difference in the trading pattern, information content and resulting impact on stock returns of arbitrage- versus valuation-based short selling activities.
