The Role of the Options Market in the Dissemination of Private Information

This paper examines the role the options market plays in the dissemination of private information. We find abnormal volume in the options market for three days prior to management forecasts, controlling for concurrent equity volume. Classifying trades as long or short, we find more informed options volume relative to equity volume (1) with relatively greater options market liquidity; (2) when equity is listed on the NYSE or AMEX; (3) for larger surprises; (4) with fewer analysts; (5) for shorter times between the forecast and period end; (6) for good news forecasts; and (7) for smaller percentage institutional holdings.

Linguistic tone and the small trader

Management-issued linguistic tone is, on average, positively associated with future earnings and incrementally priced by the market. However, prior capital markets research also shows that linguistic tone is difficult to process, while lab-based findings establish that less sophisticated investors are more susceptible to the use of heuristics in their interpretation of tone. Taken together, these findings motivate us to examine whether investors disagree on the valuation implications of linguistic tone and whether small investors are subject to differential, and notably less efficient, trading in response to the linguistic tone in these corporate announcements. We measure “residual tone” (i.e., that portion of linguistic tone that is not associated with contemporaneous economic news or current valuation fundamentals) for a sample of publicly-released management forecasts. We find that abnormal trading volume is increasing in the residual tone of management forecasts after controlling for the price reaction to forecasts, suggesting that there is significant investor disagreement over the implication of this tone for firm value. Further tests show that the net buying behavior of small investors is positively associated with residual tone, while larger investors tend to sell on this signal. The negative relation between residual tone and future stock returns found in prior work on earnings announcements holds in our sample of management forecasts as well, implying that this differential buying behavior involves an economically significant wealth transfer from small to large investors. We show in an extended analysis that any success that might accrue to small investors from trading positions taken during the event period is decreasing in residual tone
