Title: Citadel Takes 10% Coal Stake

Every weekend, I dig into our insider activity tracker looking for the biggest conviction buys — and this week, we have action from deep-value investors and some of the world’s top hedge funds — all putting fresh money to work in key sectors.

Here’s what stands out:

Let’s kick things off with Biglari Holdings $BH, owner of properties such as Steak ‘n Shake and Maxim Magazine. GAMCO Investors, led by Mario Gabelli, just boosted its stake from 6.19% to 6.49%. 

Gabelli’s firm has a long track record of uncovering value in overlooked corners of the market, and this incremental move shows continued confidence in BH.

In the resource space, Citadel Advisors LLC filed an original 13G showing a 9.99% stake in American Resources Corp $AREC. 

It’s not every day you see Citadel step into the coking coal business — a notable sign that institutional players may be warming back up to the energy complex.

Over in the rails, CSX Corp $CSX saw a strong insider buy from its President & CEO, totaling just over $2 million.

Few things speak louder than the boss putting some fresh skin in the game.

On the institutional side, Millennium Management disclosed a fresh 5.20% position in Invesco Ltd $IVZ.

Meanwhile, Cohen & Steers $CNS caught attention as its Executive Chairman scooped up nearly $2.85 million worth of stock. 

In crypto, MicroStrategy $MSTR logged a $2.3 million insider buy from director Jarrod Patten.

And to round things out, Rep. Scott Franklin disclosed a $52K–$130K purchase of Union Pacific $UNP — making for two railroads on our insider buy list this week.
