This study analyzes the motivations for and consequences of funds' credit default swap (CDS) investments using mutual funds' quarterly holdings from pre‐ to postfinancial crisis. Funds invest in CDS when facing unpredictable liquidity needs. Funds sell more in reference entities when the CDS is liquid relative to the underlying bonds and buy more when the CDS‐bond basis is more negative. To enhance yield, funds engage in negative basis trading and sell CDS with the highest spreads within rating categories, and with spreads higher than those of their bond portfolios. Funds with superior portfolio returns also demonstrate more skill in CDS trading.

Strong conflicts of interest exist within investment banks: the investment banking division possesses substantial private information, and the asset management division seeks such information. This raises the question of whether the asset management division benefits from an information advantage on client firms. While prior examinations of advisor bank trading in client firms have focused on stocks and found mixed results, we argue that the options market represents a more attractive venue for such trading. We find significant evidence of advisor banks trading in client firm options ahead of merger announcements, but no evidence of similar trading in client firm stock.

During 1980–2000, an average of 310 companies per year went public in the United States. Since 2000, the average has been only 99 initial public offerings (IPOs) per year, with the drop especially precipitous among small firms. Many have blamed the Sarbanes-Oxley Act of 2002 and the 2003 Global Settlement’s effects on analyst coverage for the decline in IPO activity. We find very little support for the conventional wisdom, and we offer an alternative explanation. Our economies of scope hypothesis posits that the advantages of selling out to a larger organization, which can speed a product to market and realize economies of scope, have increased relative to the benefits of operating as an independent firm.
