Every weekend, I dig into our insider activity tracker looking for the biggest conviction buys — and this week checked all the boxes: Baker Bros, coal stocks, big software bets, and precious metals.
The largest insider buy on today's list comes in a Form 4 filing by Carl Icahn, who revealed a purchase of $11.2 million in Southwest Gas Holdings $SWX.
Icahn now owns 15.65% of outstanding shares of SWX.
