Advertising technology company PubMatic is a small-cap name, but it may offer a big opportunity with the right covered call trade. The roughly $1.22 billion market-cap company went public in 2020, and like other businesses that began trading publicly at that time -- either through IPOs or special purpose acquisition company craze -- the shares initially shot up, only to subsequently sell off significantly over the following quarters. The company posted robust quarterly earnings this week, and investors who had already dumped PUBM might have thrown the baby out with the bathwater.
