The information content of conversion‐forcing bond calls depends on the after‐tax cash flow to bondholders. If the dividend after conversion exceeds the after‐tax coupon but is less than the before‐tax coupon, the call reveals unanticipated decreases in dividends and/or earnings that reduce the tax shield from interest payments. In contrast, a call when the dividend is less than the after‐tax coupon reveals the timing of an anticipated shift from exceptional firm‐specific positive growth to the industry norm. Efforts to document properties of convertible calls are subject to sample‐selection bias because calls are disproportionately associated with positive pre‐call firm‐specific growth.

In many markets, changes in the spot price are partially predictable. We show that when this is the case: (1) although unbiased, traditional regression estimates of the minimum variance hedge ratio are inefficient, (2) estimates of the riskiness of both hedged and unhedged positions are biased upward, and (3) estimates of the percentage risk reduction achievable through hedging are biased downward. For natural gas cross hedges, we find that both the inefficiency and bias are substantial. We further find that incorporating the expected change in the spot price, as measured by the futures-spot price spread at the beginning of the hedge, into the regression results in a substantial increase in efficiency and reduction in the bias.

Using proprietary energy futures position data, we provide evidence that mean hedger profits are negative whereas speculator (especially hedge fund) profits are positive, that traders (whether speculators or hedgers) who hold net positions opposite in sign to likely hedgers in aggregate have higher profits than traders whose net positions align with likely hedgers, and that profits on long positions vary inversely with inventories and directly with price volatility. These findings are consistent with the risk premium, hedging pressure, and modern theory of storage hypotheses, respectively. Further, our findings suggest that commodity futures momentum may be due largely to hedging pressure.

We examine the impact of scheduled macroeconomic news announcements on interest rate and foreign exchange futures markets. We find these announcements are responsible for most of the observed time‐of‐day and day‐of‐the‐week volatility patterns in these markets. While the bulk of the price adjustment to a major announcement occurs within the first minute, volatility remains substantially higher than normal for roughly fifteen minutes and slightly elevated for several hours. Nonetheless, these subsequent price adjustments are basically independent of the first minute's return. We identify those announcements with the greatest impact on these markets.

We examine the reaction of common stock returns to bond rating changes. While recent studies find a significant negative stock response to downgrades, we argue that this reaction should not be expected for all downgrades because: (1) some rating changes are anticipated by market participants and (2) downgrades because of an anticipated move to transfer wealth from bondholders to stockholders should be good news for stockholders. We find that downgrades associated with deteriorating financial prospects convey new negative information to the capital market, but that downgrades due to changes in firms' leverage do not.
