Insider Buys: WCN, KHC, and ONON Executives Bet Millions on Their Own Stocks
Top executives at WCN, KHC, and ONON signaled strong confidence in their firms with over $16 million in open-market purchases this week.
Why insider buys matter
Academic research consistently shows that open-market purchases by top-tier executives outperform the broader market by an average of 5% to 10% annually. Unlike stock options or restricted stock units, these purchases require the executive to deploy their own liquid capital, signaling a genuine belief that the stock is undervalued.
When a CEO buys shares, it often serves as a floor for the stock price. Investors view these moves as a signal that internal projections for earnings growth or margin expansion are more optimistic than current analyst consensus estimates.
The buyers
The following table details the most significant open-market transactions reported to the SEC for the week ending May 15, 2026.
- Ronald J. Mittelstaedt (CEO, WCN): 50,000 shares at $152.24, totaling $7.61 million.
- Steven A. Cahillane (CEO, KHC): 213,106 shares at $23.46, totaling $5.00 million.
- David Michael Allemann (Co-CEO, ONON): 50,856 shares at $36.75, totaling $1.87 million.

- Caspar Felix Coppetti (Co-CEO, ONON): 50,853 shares at $36.75, totaling $1.87 million.
Stock-by-stock read-through
The market reaction to these buys has been mixed, reflecting the specific challenges facing each sector, from industrial waste management to consumer packaged goods and footwear.
- WCN: Bullish signal as the CEO increases his stake by 20% following a Q1 earnings beat that reaffirmed full-year guidance.
- KHC: A rare $5 million buy from the CEO suggests the turnaround plan is gaining traction after the company reported its first positive revenue growth in five quarters.
- ONON: The synchronized buying from the three co-founders provides a vote of confidence in the new leadership structure following the May 1, 2026 transition.
How to trade the signal
Retail investors should treat these buys as a starting point for fundamental analysis rather than a direct signal to enter a position. Focus on the timing of the buy relative to the company's recent earnings reports and 52-week price performance.
For WCN and KHC, the proximity to 52-week lows suggests that insiders are attempting to capitalize on what they perceive as an oversold environment. Conversely, the ONON purchases reflect long-term founder alignment during a period of global scaling.
