A 10% owner's $114.7M open-market buy is a strong conviction signal, but RSG's historical insider signals have not translated to positive short-term returns (14% win rate, -1.69% avg T+20). Monitor for any accompanying 8-K or press release explaining the purchase rationale. If no catalyst emerges, the signal may be a long-term position build rather than a near-term trading event.
Price Chart
Executive Summary
A 10% owner, Cascade Investment L.L.C., made a concentrated open-market purchase of ~$114.7M in RSG shares over a week, representing ~0.17% of the company's $65.9B market cap. This is a material conviction buy from a large insider, but the historical performance of prior RSG reports shows a 14% win rate and negative average returns, suggesting the market has not rewarded similar insider signals recently. The filing is a standalone bullish signal, but the calibration data indicates that high-score bullish calls on RSG have underperformed, warranting a tempered impact score.
