Recent insider selling of Trinity Industries shares, especially by the CFO, is concerning. The absence of purchases suggests insiders don't see the shares as a bargain. Despite earnings growth and decent insider ownership, the sales history calls for caution before investing.

Trinity Industries' high P/E ratio is backed by its robust forecast growth, outpacing the broader market. Shareholders remain optimistic about future earnings, showing no interest in selling the stock. The share price is expected to remain stable in the near term.
