Odaily Planet Daily News reports that there are market rumors that MicroStrategy (MSTR) may not sell stocks through ATM or issue new convertible bonds to raise funds to purchase Bitcoin in January next year. This behavior may cause concern among some long-term MicroStrategy stockholders, as they have been anticipating the company to purchase Bitcoin weekly. 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 during the earnings report season and the period of earnings announcements (assuming all other disclosures are up to date), many companies still set their own insider trading blackout periods as a Wall Street practice. Insider trading blackout periods typically last from two weeks to one month, and most companies allow insider trading again within two days after quarterly earnings announcements are released.
