We've highlighted recently that Warren Buffett's Berkshire Hathaway has been buying Liberty Sirius XM (LSXMA / LSXMK). Well, they're at it again.

Per Form 4's filed with the SEC, Berkshire acquired 377,656 shares of LSXMA across May 26th, 30th, and 31st at weighted average prices around $41.xx. After these buys, they own over 14.86 million LSXMA shares.

The second Form 4 indicates they also bought 644,172 LSXMK shares on May 26th, 30th, and 31st at weighted average prices ranging from $40.9877 to $41.7432. After these buys, they own over 31 million LSXMK shares.

We've also previously noted that it seems likely that Berkshire's portfolio manager Ted Weschler is the one buying here.
