The Oracle of Omaha has once more bolstered his stake in a media giant’s tracking stocks. However, Warren Buffett is not the only 10% owner or other insiders who made notable insider purchases in the past week or so.

A well-known adage reminds us that corporate insiders and 10% owners really only buy shares of a company because they believe the stock price will rise and they want to profit from it. Thus, insider buying can be an encouraging signal for potential investors. This is all the more so during times of uncertainty in the markets, and even when markets are near all-time highs.

Remember that even as the earnings-reporting season winds down, some insiders are prohibited from buying or selling shares. Below are some of the more notable insider purchases that were reported in the days leading up to the ides of March, starting with the largest one.
