Insider buying momentum is strongest at Republic Services this month. ORTEX data shows the waste-management giant leads the US market for insider purchases over the past 30 days. The timing is notable. Earnings just beat estimates and analysts raised their dividend outlook. With the stock flat year-to-date and a "Moderate Buy" consensus, the buying looks like a bet on undervaluation.
On the selling side, two big names stand out. Diamondback Energy insiders filed share sales this week, pushing the stock lower. A news headline noted the stock "falls from recent highs after insider share sale." Diamondback is up 26% year-to-date, so locking in gains makes sense — but the timing right after positive EPS revisions makes it worth watching.
NVIDIA also registers among the heaviest insider selling over the past month. With the stock up nearly 22% year-to-date and at a $5.3 trillion market cap, executives are cashing out. Apple's public challenge to NVIDIA's AI economics — new Macs advertised as having "no cost per token" — adds an interesting backdrop to the timing of those sales.
Dell Technologies rounds out the sellers list. The stock has surged an extraordinary 357% year-to-date, so insider profit-taking is unsurprising. Insider selling into strength at these valuations carries less signal than discretionary selling into weakness.
The clearest buy signal remains RSG. The rest looks like rational profit-taking near highs.
