The impact of sovereign wealth funds on global financial markets

Abstract: This paper analyses the impact of sovereign wealth funds (SWFs) on global financial markets. It presents back-of-the-envelope calculations which simulate the potential impact of a transfer of traditional foreign exchange reserves to SWFs on global capital flows. If SWFs behave as CAPM-type investors and thus allocate foreign assets according to market capitalisation rather than liquidity considerations, official portfolios reduce their “bias” towards the major reserve currencies. As a result, more capital flows “downhill” from rich to less wealthy economies, in line with standard neoclassical predictions. More specifically, it is found that under the assumption of SWFs investing according to market capitalisation weights, the euro area and the United States could be subject to net capital outflows while Japan and the emerging markets would attract net capital inflows. It is also shown that these findings are sensitive to alternative assumptions for the portfolio objectives of SWFs. Finally, the paper discusses whether a change in net capital flows triggered by SWFs could have an impact on stock prices and bond yields. Based on an event study approach, no evidence can be found for a stock price impact of non-commercially motivated stock sales by Norway’s Government Pension Fund. JEL Classification: F30, F40, G15.

Stock Price Clustering on Option Expiration Dates

Abstract: This paper presents striking evidence that option trading changes the prices of underlying stocks. In particular, we show that on expiration dates the closing prices of stocks with listed options cluster at option strike prices. On each expiration date, the returns of optionable stocks are altered by an average of at least 16.5 basis points, which translates into aggregate market capitalization shifts on the order of $9 billion. We provide evidence that hedge re-balancing by option market-makers and stock price manipulation by firm proprietary traders contribute to the clustering.

Foreign Investment Fluctuations and Emerging Market Stock Returns: The Case of Mexico

Abstract: We investigate the economically and statistically significant positive correlation between monthly foreign purchases of Mexican stocks and Mexican stock returns. We find that a 1 percent of market capitalization surprise foreign inflow is associated with a 13 percent increase in Mexican stock prices. We explore whether this correlation might be explained by permanent reductions in conditional expected returns resulting from expansion of the investor base along the lines modeled by Merton (1987), or correlations with other factors causing returns, price pressures, or positive feedback strategies by foreign investors, and conclude that the available evidence is consistent with the base-broadening hypothesis.

Does corporate governance matter? A crude test using Russian data

Abstract: Does a firm's corporate governance behavior affect its market value? In most empirical tests in developed countries, firm-specific corporate governance actions have little or no effect on market value. These weak results could reflect limited variation amongfirms in governance practices. In contrast, the corporate governance practices of Russian firms vary widely, from quite good to awful. I test whether corporate governance behavior affects the market value of Russian firms using (I) fall 1999 corporate governance rankings developed by a Russian investment bank for sixteen Russian public companies and (2) the "value ratio" of actual market capitalization to potential Western market capitalization for these firms, determined independently at the same time by a second Russian investment bank. The correlation between In(value ratio) and governance ranking is striking and is statistically strong despite the small sample size: Pearson r = 0.90 (p < .0001). A one-standard-deviation improvement in governance ranking predicts an 8-fold increase in firm value; a worst (51 ranking) to best (7 ranking) governance improvement predicts a 600-fold increase in firm value. My results are tentative, due to the small sample size. But they suggest that a firm's corporate governance behavior can have a huge effect on its market value in a country where other constraints on corporate behavior are weak.

How Efficient are Africa's Emerging Stock Markets?

Abstract: The development of financial institutions has been viewed in recent years as critical to the economic development process. This research uses recent data from the eight largest African stock markets to test whether these markets meet the criterion of weak-form stock market efficiency with returns characterised by a random walk. Results are then compared with similar tests on emerging stock markets in South-east Asia and Latin America. Conclusions from the research indicate that test results for weak-form efficiency in the emerging African stock markets compare favourably with those performed on other emerging stock markets.
