A study by Roll, Schwartz, and Subrahmanyam found that options trading around earnings announcements has been steadily increasing every year since Before we begin with specific trading strategies, it makes sense to get a sense of the general behavior of options around earnings announcement periods.
Several studies have considered this issue with respect to options prices. Part of this is certainly because earnings information probably is leaked early. However, even if there were no information leak, this suggests that sophisticated institutional investors are estimating earnings accurately before they are announced.
Contrast that with companies that have no options listed or traded. Remember, nonoptioned companies tend to be small-cap companies that not as many people pay attention to. Indeed, several studies examine this issue. For instance, a study by Mendenhall and Fehrs and another by Kim and Lee suggest that, if you are an informed trader with valuable information that the public does not have Well, where would you go to extract the biggest bang for your buck?
Many investment websites and blogs take the time to tell their readers about large options positions that have recently been opened for certain companies. In the preannouncement period, we know that smart money puts on trades to exploit their superior information.
They found that more long call positions and short put positions were opened before positive earnings surprises. Similarly, they found that more long put and short call trades were put on before bad earnings surprises. Roll, Schwartz, and Subrahmanyam also found that this effect was even stronger for companies that had a relatively higher number of analysts who follow the company and for companies with higher levels of institutional ownership. For more than 30 years, when a study by Patell and Wolfson was published, we have also known that the implied volatility of options tends to increase in the earnings preannouncement period.
This is because nerves are frayed in the frenzied anticipation of the news. But the difference is even more pronounced right before earnings announcements. A study by Donders, Kouwenberg, and Vorst found similar increases in the open interest and trading volume of options in the preannouncement period. And the higher the options trading volume in the preannouncement period, the stronger the price anticipation during this period.
A study by Corrado and Truong also confirms this. In general, these studies suggest that much action occurs in the preannouncement period.
Earnings announcements are the most prominent, regularly recurring corporate event for publicly traded companies. Last, how things happen in the preannouncement period can predict how things will play out during the actual earnings announcement.
Another finding of the Roll, Schwartz, and Subrahmanyam study is that higher trading volume in the preannouncement period tends to equate to less trading volume for the market reaction to the announcement itself. The more the action has been impounded into option prices in the preannouncement period, the less action the actual announcement will have. After all, only so much news can get impounded. The authors also found that, if relative options trading volume is high when the announcement happens such as during the announcement day , the change in option prices also tends to be higher.
That is, higher volume is related to bigger price action regardless of the preannouncement trading volume. To sign up for the jobs feed, click here. You don't need to be a CFA charterholder to join!

The idea that companies with listed options have a larger amount of information impounded into their stock prices makes intuitive sense. And this is precisely what a study by Amin and Lee found about optioned companies. They found that this better information impounding happened for optioned companies in both their earnings announcement periods and their non-earnings-announcement periods—basically, all the time.
They found that the price adjustment to earnings news in the immediate aftermath of an announcement is faster for optioned companies than it is for nonoptioned companies. What this discussion means for you in a practical sense is that it is unlikely that you, as an individual investor with limited resources, will have a consistent informational advantage over the market as a whole or over more sophisticated institutional investors.
