The Society for Financial Society (SFS) is a global, nonprofit academic society in finance. It owns and runs three academic journals: (1) the Review of Asset Pricing Studies, (2) the Review of Corporate Finance Studies, and (3) the Review of Financial Studies. It also organizes two annual academic conferences: (1) the SFS Cavalcade Asia-Pacific and (2) the SFS Cavalcade North America. It also runs several smaller, specialized conferences and financially supports and co-sponsors other independent conferences. Its governing board is the SFS Council. This annual report provides an overview of SFS activities during 2019-2020, including all three journals, both Cavalcade conferences, and the SFS financial and policy report. The purpose of this annual report is to share this information more broadly with SFS members and friends and to create a permanent record for the long-run (i.e., institutional memory). 2020 was a busy year for the Review of Asset Pricing Studies (RAPS). We renewed Associate Editors Clemens Sialm and Dimitri Vayanos. We added a special COVID-19 issue. This issue contained 11 papers and an introduction by Lars Peter Hansen. We expect that these papers will provide a foundation for future finance and economics research that is related to COVID.

Unlike previous studies that examine how emerging market return volatility changes subsequent to stock market liberalization, this paper investigates the impact of investibility, or the degree to which a stock can be foreign-owned, on emerging market volatility. We find a positive relation between return volatility and the investibility of individual stocks, even after controlling for country, industry, firm size, and turnover. We also find that a highly investible emerging market portfolio is subject to larger world market exposure than a non-investible portfolio, suggesting that highly investible stocks are more integrated with the world and therefore more vulnerable to world market risk.

We examine the trading behavior of Chinese domestic investors after they were given access to the B-share market in 2001. Surprisingly, we find that only 2% of investors began buying B shares. Even among these 2%, investors were less likely to buy B shares if they had more experience in the A-share market, and vice-versa. Thus, prior market experience limits the extent to which investors respond to A/B-share premiums and liquidity and lowers their performance. Our findings cannot be explained by government intervention, investor heterogeneity, foreign currency constraint, A/B-share liquidity or speculation differentials, or information advantage.

We extend previous studies on the effect of behavioral biases on investor hold/sell decisions, and examine whether behavioral biases affect the order submission strategies. We use a unique database provided by the Shanghai Stock Exchange, which contains order submissions and executions as well as trading records of all investors. We find investors are less aggressive in submitting sell orders for stocks that experienced losses, and more aggressive in submitting sell orders for stocks that experienced gains. The sell order aggressiveness is negatively related to the size of losses, but has a quadratic relationship with the size of gains. Results are consistent with the combination of the disposition and the house money effects.

Fund flows are more correlated among funds with similar investment horizon, consistent with correlated demand for liquidity. We find that stocks held by institutions with more heterogeneous investment horizon are more liquid and have lower volatility of liquidity. Identification tests confirm that the improvement in stock liquidity holds when the increase in investor heterogeneity arises from an exogenous shock due to the 2003 tax reform. In addition, extreme flow-induced trading by institutional funds has a bigger price impact when stocks have a less heterogeneous investor base. Moreover, the premium associated with stock illiquidity is concentrated in stocks with low investor heterogeneity.

We investigate the long-term effects of S&P 500 index additions and deletions on a sample of stocks from 1962 to 2003 and find a significant long-term price increase for both added and deleted stocks, with deleted stocks outperforming added stocks. The long-term price increase for added stocks can be attributed to increases in institutional ownership, liquidity, and analyst coverage, and a decrease in the shadow cost in the long-term. However, while deletion has no significant effect on analyst coverage and shadow cost, we find a rebound in the institutional ownership and liquidity of deleted stocks. The difference in the long-term price increase of added and deleted stocks can be explained by analyst coverage and operating performance.

We examine the price behavior and market activity of the Jardine Group companies after they were delisted from Hong Kong in 1994. Although the trading activity of the Jardine Group moved to Singapore, the core businesses remained in Hong Kong and Mainland China. Evidence indicates the Jardine stocks are correlated less (more) with the Hong Kong (Singapore) market after the delisting. This result cannot be explained by various hypotheses, such as relocation of core business, time‐varying betas, migration of trading activity, and currency and tax distortions. We conclude that price fluctuations are affected by country‐specific investor sentiment.

We study the intraday impact of exchange rate news on emerging market American Depositary Receipts (ADRs) and closed‐end country funds during the 1994 Mexican peso crisis. Peso exchange‐rate changes affect prices and trading volumes of Latin American equities, and some closed‐end fund behavior is consistent with “noise trader” theories of small investors. However, there is no evidence that peso depreciation triggers a significant sell‐off of non‐Mexican securities or that other non‐Mexican trading patterns change at times of high peso news flow. Thus, the “Tequila Effect” is largely confined to price changes.

While many studies find that option prices lead stock prices, Stephan and Whaley (1990) find that stocks lead options. We find no evidence that options, even deep out‐of‐the‐money options, lead stocks. After confirming Stephan and Whaley's results, we show their results can be explained as spurious leads induced by infrequent trading of options. We show that the stock lead disappears when the average of the bid and ask prices is used instead of transaction prices. Hence, we find no evidence of arbitrage opportunities associated with the stock lead.
