Caught something interesting on the SEC filings - Gunnar Gudlaugsson, who's an EVP at Century Aluminum, just dumped 43,000 shares for about $2.3M back in late February. That's his biggest sale since at least early 2024, so worth paying attention to when insiders make moves like that.

Here's the thing though - the company's actually in a pretty solid position right now. They announced this huge partnership with Emirates Global Aluminum to build the first aluminum smelting plant in the US in nearly 50 years. Century's got a 40% stake in it, and with tariffs pushing aluminum prices up, the timing seems pretty good. The stock was already up like 150% last year before this EVP sold his shares.

So is this a red flag or just normal portfolio rebalancing? Hard to say. Could be he just wanted to lock in gains, or maybe he's seeing something. Either way, the company's fundamentals look decent with that partnership deal and the whole push for domestic aluminum production. Worth keeping an eye on if you're looking at industrial plays.
