Evansbrook LLC Expands Stakes in Major Firms as Insiders Sell Shares Amid Dominant Institutional Ownership

At CME Group, insider Hilda Harris Piell sold 5,753 shares at an average price of $304.63 for $1,752,536.39; after the sale, she still directly owned 27,702 shares (about an additional $8.44 million), representing a 17.20% decrease in her stake.
At General Dynamics, EVP Mark Lagrand Burns sold 36,480 shares at an average price of $345.29 for $12,596,179.20; after the transaction, he held 38,975 shares worth about $13,457,677.75, a 48.35% reduction in his position.
While institutional/hedge-fund ownership was described broadly, the articles provided specific concentration figures for several companies: Sysco (83.41%), General Dynamics (86.14%), PNC Financial Services Group (83.53%), and U.S. Bancorp (77.60%).
For Sysco (SYY), the article included market-performance context: shares opened at $78.64, with a 50-day moving average of $75.30 and a 200-day moving average of $78.29 (and a stated 12-month low of $68.19).
For PNC (PNC), the article added trading and valuation metrics: the stock opened at $232.39, had market capitalization of $93.32 billion, a P/E ratio of 13.50, a price-to-earnings-growth ratio of 0.97, beta of 0.92, and was noted as “Trading Down 0.3%.”
CME Group announced on June 17 that CEO Terry Duffy will step down in March 2027, handing the reins to President and CFO Lynne Fitzpatrick — making her the first female CEO in the exchange's history, according to PR Newswire. The very next day, Duffy appeared on CNBC to announce CME is suing the Commodity Futures Trading Commission over its approval of "perpetual futures" contracts for crypto platforms like Kalshi and Coinbase, according to CNBC.
The twin moves — a planned leadership handoff and an all-out legal war with its own regulator — place CME Group at a crossroads. The exchange, which has grown its market cap by more than 8,000% since its 2002 IPO, is fighting to protect its core business while trying to project stability to investors, Reuters reported.
Fitzpatrick's new contract includes a $1.2 million base salary and a long-term incentive target of 700% of her base pay, according to Stock Titan. Duffy will not disappear entirely — he transitions to Executive Chairman on March 1, 2027. Analysts at Piper Sandler called Duffy "legendary" but expressed "high confidence" in Fitzpatrick, saying the handoff was built for maximum continuity, per BNN Bloomberg.
Duffy spent 25 years turning CME from a floor-based trading pit into a $95 billion electronic powerhouse. The structured, multi-year succession plan signals the board wants a smooth transition — even as the company wages an aggressive legal battle outside its walls.
At the center of the lawsuit is the CFTC's approval of "perpetual futures" — contracts with no expiration date that use floating interest-like payments called "funding rates" to track spot prices. These products were previously banned in the U.S. and traded mostly on offshore, unregulated platforms. Duffy told CNBC that the Dodd-Frank Act defines these as "swaps," not futures, calling the CFTC's approval "a disaster waiting to happen."
CFTC Chairman Michael Selig fired back, defending the decision to approve crypto perpetuals for Kalshi and Coinbase. "It's time to approve regulated futures contracts that have no expiration date," Selig said. "We're going to make [the market] transparent." Kalshi CEO Tarek Mansour was blunter. A company spokesperson told the Financial Times: "This isn't about the law, it's about the fear of competition."
Even as the legal drama unfolds, CME insiders have been cashing out. Senior MD and Chief HR Officer Hilda Harris Piell sold 5,753 shares at $304.63 each on May 18, netting $1.75 million — a 17.2% cut to her direct stake, according to MarketBeat. Over at General Dynamics, EVP Mark Lagrand Burns sold 36,480 shares at $345.29 each for $12.6 million on May 12, slashing his position by nearly half, per Investing.com.
Despite the insider selling, large institutional investors are not moving for the exits. Institutional ownership sits at 87.75% for CME Group, 86.14% for General Dynamics, 83.53% for PNC Financial, and 77.60% for U.S. Bancorp, according to Quiver Quantitative. Meanwhile, Evansbrook LLC filed new positions in CME Group (2,342 shares), Sysco, U.S. Bancorp (16,768 shares worth $895,000), and PNC Financial in its latest 13F, per Ticker Report.
If CME wins in court, perpetual futures could be reclassified as "swaps" under Dodd-Frank. That would push them into an institutional-only category, effectively blocking retail crypto platforms from offering them in the U.S., according to Bankless. That is a massive commercial win for CME, which runs the dominant regulated derivatives market in the country.
Critics see it differently. Legal analyst Jake Chervinsky argued the lawsuit is a move to protect a "monopolistic business model" from more efficient 24/7 contracts, per Bankless. The CFTC called the litigation "lawfare" against Washington's "pro-innovation agenda," the Financial Times reported. Under Fitzpatrick, CME is expected to expand its Google Cloud partnership and its FanDuel venture — but the court battle over who controls the future of U.S. derivatives may define her tenure before it even starts.
