Uncle Warren is back in the buying game.

When Warren Buffett and Berkshire Hathaway start buying, it’s time to sit up and take notice. 

The Oracle of Omaha has returned to the open market with three intriguing purchases. Let’s dive into them.

First up, Occidental Petroleum $OXY. After a six-month hiatus, Buffett is back, snapping up shares. This marks the 29th Form 4 filing for OXY since he began building his position in early 2022. 

Berkshire shelled out $400 million this time, bringing Buffett’s average purchase price to $54.02. 

Here’s a chart highlighting the timing of Buffett’s $OXY purchases:

Leading today’s list is Ariel Emanuel, CEO of TKO Group Holdings $TKO, making waves with an eye-popping $77 million purchase. 

When a CEO drops this kind of cash on their own stock, it screams confidence in the company’s future.

Kenneth Courtis, independent director of Alpha Metallurgical Resources $AMR, followed suit with a hefty $2.4 million buy. Insider moves like this often hint at good things to come, or at least an upward move in the stock.

Baker Bros Advisors, renowned for their biotech expertise, increased their stake in Bicycle Therapeutics $BCYC from 19.76% to 22.90%, as disclosed in a 13D filing. 

This signals strong confidence in the company's prospects, likely tied to its innovative "Bicycles" platform for developing novel therapies. 

Given the Bakers' track record, their investment is a notable endorsement of Bicycle Therapeutics' potential. 

In essence, when the Bakers buy, biotech investors pay attention.

This adds weight to the vision of CEO Anthony Noto, who demonstrated his confidence with $10 million in insider buys between March 2022 and May 2024.

The stock has officially left the station, completing a classic bottoming formation and now surging higher with authority:

The largest insider buy on today’s list comes via a Form 4 filing by TKO Group $TKO director Egon Durban.

Durban revealed a massive purchase of TKO shares for a total value of $48,133,338.

Frost is clearly placing his chips on OPKO’s future.
