The Price Response to S&P 500 Index Additions and Deletions: Evidence of Asymmetry and a New Explanation (.pdf)

Chen, Noronha, and Singal report in a forthcoming JF article that when stocks are dropped from the S&P 500, there is a temporary price decline. However when firms are added, the increase is seemingly permanent. This asymmetry is seemingly counter to most widely held views that demand curves for individual stocks are elastic. The authors suggest that this asymmetry is due to … [ Read more ]

Governance Mechanisms and Equity Prices (.pdf)

Internal and external monitoring have a strong complementary (synergistic) effect.

To test this, the authors construct various portfolios and find that those firms who measure high on both categories outperform others in the sample. … [ Read more ]

The Foundations of Freezeout Laws in Takeovers (.pdf)

Why include a freeze-out provision in takeover contracts? Because if not, investors would not tender shares. How is that? Consider the Grossman-Hart (1980) view that if the takeover is in fact value maximizing, then shareholders would have an incentive to not tender their shares but to wait for the stock price to increase. Of course if shareholders knew this, then they … [ Read more ]

Adding an Ethical Dimension to Portfolio Management

The Pack Mentality: A Behavioral Finance View of Stock Price Comovement

By looking carefully at data on individual stock prices, it is easy to find many examples of “comovement” – groups of stocks whose prices tend to move together.

Are Unmanaged Earnings Always Better for Shareholders?

Is earnings management always bad? No, if you believe the new paper by Arya, Glover, and Sunder. They point out that Earnings management can reduce the noise inherent in earnings and thereby reduce investor uncertainty.

One Simple Test of Samuelson’s Dictum for the Stock Market

Jung and Shiller have an interesting paper that looks at Samuelson’s dictum: that is that the market is more efficient pricing individual stocks than getting the overall price level (i.e. the market) correct.
