Foolish take

While Mr. Heyneman's Nov. 21 sale represented a substantial reduction in his direct holdings, he still indirectly owns over one million shares in First Interstate BancSystem. This suggests he still has a positive outlook towards the stock's future prospects. In fact, First Interstate stock is not far from its 52-week high of $35.81 reached in November of 2024, which may have spurred Mr. Heyneman's sale.

First Interstate achieved net income of $71.4 million in the third quarter compared to $55.5 million in 2024. This led to $0.69 per diluted share in Q3 versus $0.54 per diluted share in the prior year. Although these results were positive, the financial institution's Q3 net loans held for investment fell to $15.8 billion, a 12% year-over-year decline.

Mr. Heyneman's reduction in direct holdings isn't a red flag to sell, given he still maintains a substantial sum in indirect holdings. If you own shares, it's not a bad time to sell. That said, it's not the ideal time to buy, considering First Interstate's stock is near its high. The prudent approach is to wait for the share price to drop before deciding to pick up the stock.
