Option implied volatilities and the cost of issuing equity

Journal of Banking & Finance 2014 47, 88-101
The structure of a firm-commitment Seasoned Equity Offering (SEO) resembles a put-option underwritten by an investment bank syndicate (Smith, 1977). Employing implied volatilities from issuers’ stock options as a direct forward-looking measure, this paper examines the impact of expected price risk around SEO issue dates on the direct cost of issuing equity. Using a comprehensive sample of 1208 SEOs between 1996 and 2009, we find issuers with higher option implied volatilities raise less external equity capital and pay higher investment bank fees in the stock market, ceteris paribus. The effect of implied volatility on the investment bank fees is stronger for larger issuers with lower pre-SEO abnormal realized stock volatilities, and for SEOs with higher expected price pressures around issue dates. These relationships are robust to adjustments for correlations among control variables, sample selection bias and also simultaneous determination of offer size and SEO fees.

Call-Put Implied Volatility Spreads and Option Returns

The Review of Asset Pricing Studies 2013 3(2), 258-290
Prior literature shows that implied volatility spreads between call and put options are positively related to future underlying stock returns. In this paper, however, we demonstrate that the volatility spreads are negatively related to future out-of-the-money call option returns. Using unique data on option volumes, we reconcile the two pieces of evidence by showing that option demand by sophisticated, firm investors drives the positive stock return predictability based on volatility spreads, while demand by less sophisticated, customer investors drives the negative call option return predictability. Overall, our evidence suggests that volatility spreads contain information about both firm fundamentals and option mispricing.

Does firm life cycle stage affect investor perceptions? Evidence from earnings announcement reactions

Review of Accounting Studies 2024 29(2), 1039-1096 open access
This paper argues that firms in certain life cycle stages may be more subjectively valued by individual investors, leading to an optimistic bias in stock prices that is subsequently corrected upon the release of earnings news. Using a cash flow-based life cycle stage classification, introduction and decline stage companies exhibit three-day cumulative abnormal returns (CARs) around earnings announcements that are at least 112 bps lower than firms in growth, maturity, and shake-out stages. Specifically, introduction and decline stage stocks exhibit less positive reactions to positive earnings surprises and more negative reactions to negative earnings surprises relative to companies in other life cycle stages. Lottery stocks’ excess returns around earnings announcements (Liu et al. in Journal of Financial Economics 138: 789–817, 2020 ) also vary based on firm life cycle stage. Our findings suggest that individual investors’ optimistic expectations for introduction and decline stage stocks are met with disappointment when value-relevant earnings news is released. This study demonstrates that firm life cycle stage has real implications for stock price reactions to earnings announcements.

The information content of implied skewness and kurtosis changes prior to earnings announcements for stock and option returns

Journal of Banking & Finance 2012 36(3), 786-802
We use option prices to examine whether changes in stock return skewness and kurtosis preceding earnings announcements provide information about subsequent stock and option returns. We demonstrate that changes in jump risk premiums can lead to changes in implied skewness and kurtosis and are also associated with the mean and variability of the stock price response to the earnings announcement. We find that changes in both moments have strong predictive power for future stock returns, even after controlling for implied volatility. Additionally, changes in both moments predict call returns, while put return predictability is primarily linked to changes in skewness.
