Why do options prices predict stock returns? Evidence from analyst tipping

We study the role of analysts and options traders in the information transmission between options and stock markets. We first show that the predictive power of option implied volatilities (IVs) on stock returns more than doubles around analyst-related events, indicating that a significant proportion of the options predictability on stock returns comes from informed options traders’ information about upcoming analyst-related news. We examine three explanations for this finding: tipping, reverse tipping and common information. We find that analyst tipping to options traders is the most consistent explanation of these predictive patterns.     

Why do firms switch underwriters?

In the mid-1990s, 30% of firms completing an SEO within three years of their IPO switched lead underwriter. This article provides evidence on why they switched. Contrary to predictions of prior research, there is little evidence that firms switch due to dissatisfaction with underwriter performance at the time of the IPO. A surprising result is that switchers’ IPOs were significantly less underpriced than non-switchers’ IPOs. However, switchers raised fewer proceeds than expected, compared to the mid-point of the filing range, while non-switchers raised significantly more proceeds. There are two main reasons for switching. Firms graduate to higher reputation underwriters, and they strategically buy additional and influential analyst coverage from the new lead underwriter. Survey results support these conclusions.     

Why do central banks intervene?

Intervention by central banks, in terms of buying and selling foreign currency, has been a major activity in recent years. This paper investigates the motivations for such policy and the evidence for its effectiveness. We use high quality daily data on the dollar amounts of intervention by the central banks of the US and Germany. We also use information on agreed G7 target levels for the $/DM and $/Yen nominal exchange rates. Daily, nominal dollar exchange rate returns are well described as a Martingale-GARCH process, and we find little evidence that the different types of intervention have had much effect on the conditional mean of exchange rate returns. There is some evidence that intervention is associated with slight increases in the volatility of exchange rate returns. While little evidence is found for the effectiveness of intervention, the motivations are more clear. In particular, from the application of probit analysis we find that the probability of intervention is determined by the magnitude of the deviation of the nominal exchange rate from the agreed target level and, to a lesser extent, by the current volatility of exchange rates.     

Why do firms hold so much cash? A tax-based explanation

US corporations hold significant amounts of cash on their balance sheets. This paper develops and tests the hypothesis that the magnitude of US multinational cash holdings are, in part, a consequence of the tax costs associated with repatriating foreign income. Consistent with this hypothesis, firms facing higher repatriation taxes hold higher levels of cash, hold this cash abroad, and hold this cash in affiliates that trigger high tax costs when repatriating earnings. In addition, less financially constrained firms and those that are more technology intensive exhibit a higher sensitivity of affiliate cash holdings to repatriation tax burdens.     

The effects of capital structure change on security prices: A study of exchange offers

This study considers the impact of capital structure change announcements on security prices. Statistically significant price adjustments in firms' common stock, preferred stock and debt related to these announcements are documented and alternative causes for these price changes are examined. The evidence is consistent with both corporate tax and wealth redistribution effects. There is also evidence that firms make decisions which do not maximize stockholder wealth. In addition, a new approach to testing the significance of public announcements on security returns is presented.     

Why do NASDAQ Market Makers Avoid Odd-Eighth Quotes?

The NASDAQ multiple dealer market is designed to produce narrow bid-ask spreads through the competition for order flow among individual dealers. However, we find that odd-eighth quotes are virtually nonexistent for 70 of 100 actively traded NASDAQ securities, including Apple Computer and Lotus Development. The lack of odd-eighth quotes cannot be explained by the negotiation hypothesis of Harris (1991) , trading activity, or other variables thought to impact spreads. This result implies that the inside spread for a large number of NASDAQ stocks is at least $0.25 and raises the question of whether NASDAQ dealers implicitly collude to maintain wide spreads.     

How do house prices affect consumption? Evidence from micro data

Housing is a major component of wealth. Since house prices fluctuate considerably over time, it is important to understand how these fluctuations affect households’ consumption decisions. Rising house prices may stimulate consumption by increasing households’ perceived wealth, or by relaxing borrowing constraints. This paper investigates the response of household consumption to house prices using UK micro data. We estimate the largest effect of house prices on consumption for older homeowners, and the smallest effect, insignificantly different from zero, for younger renters. This finding is consistent with heterogeneity in the wealth effect across these groups. In addition, we find that regional house prices affect regional consumption growth. Predictable changes in house prices are correlated with predictable changes in consumption, particularly for households that are more likely to be borrowing constrained, but this effect is driven by national rather than regional house prices and is important for renters as well as homeowners, suggesting that UK house prices are correlated with aggregate financial market conditions.     

A theoretical analysis of the liquidity risk premium embedded in the prices of voting and non-voting stocks

Liquidity risk and corporate control considerations affect shareholders' willingness to invest in stocks and should thus be reflected in their prices. This paper derives the premium required by liquidity risk-averse agents who invest, respectively in non-voting and voting shares. It is shown that the liquidity risk premium depends upon the investor's risk aversion, the variance of his future consumption flow and the liquidation probability of each share type. Furthermore, liquidity risk premia depend upon the firm's capital structure decisions, the distribution and private valuation of voting rights by its shareholders.     

Why do countries matter so much for corporate governance?

This paper develops and tests a model of how country characteristics, such as legal protections for minority investors and the level of economic and financial development, influence firms’ costs and benefits in implementing measures to improve their own governance and transparency. We find that country characteristics explain much more of the variance in governance ratings (ranging from 39% to 73%) than observable firm characteristics (ranging from 4% to 22%). Further, we show that firm characteristics explain almost none of the variation in governance ratings in less-developed countries and that access to global capital markets sharpens firms’ incentives for better governance.     

Why do companies include warrants in seasoned equity offerings?

We analyze the reasons why companies issue units when they raise additional capital. We find that, in contrast to previous evidence, units are not offered to mitigate the agency conflicts or to signal security mispricing as they are predominantly issued during cold periods, in public rather than in rights offerings, and when the issue is underwritten. In addition, the results indicate that companies choose to offer units to increase their offer price flexibility and to underprice their seasoned equity offering so as to minimize the issue cost and the risk of failure of the issue. These results provide support for the net proceeds maximization hypothesis.
