There are market reports that MicroStrategy (MSTR) may not sell shares or issue new convertible bonds through ATMs in January next year to raise funds to buy Bitcoin. This behavior may worry some long-term MicroStrategy stock investors who have been expecting the company to buy Bitcoin every week. Researchers speculate that the so-called prohibition on issuing new convertible bonds is related to insider trading rules. Although the U.S. Securities and Exchange Commission (SEC) does not prohibit insiders from trading between the end of the earnings season and the release of earnings reports (assuming all other disclosures are up to date), many companies have set their own insider trading blackout period as a Wall Street practice. The insider trading blackout period usually lasts from two weeks to one month, and most companies re-allow insider trading within two days of the quarterly earnings announcement. (protos)
