Winton Group reports significant second-quarter holding increases and new positions across five companies.

Incyte represented approximately 0.9% of WINTON GROUP Ltd.’s portfolio and was its 12th-largest holding; the firm owned about 0.13% of Incyte at the quarter’s end.
The Mueller Industries position accounted for about 0.6% of WINTON GROUP Ltd.’s portfolio, ranking as its 21st-largest holding, and represented roughly 0.07% of Mueller’s shares outstanding.
Organon & Co. had substantial institutional ownership, with hedge funds and other institutional investors holding 77.43% of the company’s stock. Analysts were broadly cautious: five rated it Hold and two rated it Sell, producing a consensus “Reduce” rating and a $11.40 price target.
Take-Two Interactive Software was 95.46% institutionally owned, according to the article. Separately, CEO Strauss Zelnick sold 40,000 shares at an average price of $252.64, generating proceeds of $10.11 million.
Fortrea CEO Anshul Thakral sold 99,869 shares at an average price of $19.16, according to the article’s insider-trading disclosure, adding an executive transaction to the quarter’s institutional ownership changes.
Winton Group Ltd., a London-based quantitative investment manager, significantly reshuffled its portfolio in the second quarter, boosting stakes in five publicly traded companies and disclosing the moves in SEC filings released in August. The firm increased its Incyte position by 47% to 254,408 shares and its Fortrea Holdings stake by 26.7% to 389,155 shares, while launching new positions in Mueller Industries ($20.2 million) and Organon & Co. ($6.9 million). Watchlist News reported that Winton's most dramatic shift was a 2,526.5% jump in Take-Two Interactive Software holdings to 58,676 shares valued at roughly $14.7 million.
The portfolio moves come as insider executives at two of the targeted firms sold substantial shares. Take-Two CEO Strauss Zelnick sold 40,000 shares at $252.64 each for $10.11 million, while Fortrea CEO Anshul Thakral unloaded 99,869 shares at $19.16 per share, generating $1.91 million. The sales raise questions about executive confidence even as Winton's quantitative models signal buying opportunities.
Winton's most explosive move was its 2,526.5% increase in Take-Two Interactive Software, jumping from minimal holdings to 58,676 shares worth $14.7 million. Watchlist News notes that Take-Two is 95.46% institutionally owned, meaning large fund trading can move share prices sharply. Yet CEO Zelnick's $10.11 million sale of 40,000 shares at peak pricing signals potential caution from the company's top executive about valuations at current levels.
Winton boosted its Incyte position by 47% to 254,408 shares, making it the fund's 12th-largest holding and roughly 0.9% of its $3.09 billion portfolio. Watchlist News reports Winton now owns about 0.13% of Incyte's total shares outstanding. The biotech expansion reflects Winton's systematic model selecting healthcare assets for possible growth, though the smaller ownership stake suggests measured conviction rather than a concentrated bet.
Winton opened fresh positions in Mueller Industries (164,130 shares, $20.2 million) and Organon & Co. (509,862 shares, $6.9 million) during the quarter. According to Watchlist News, Mueller ranks as Winton's 21st-largest holding at 0.6% of portfolio weight. Organon is 77.43% institutionally owned, yet Wall Street analysts remain skeptical: five rate it Hold and two rate it Sell, producing a consensus Reduce rating with a $11.40 price target. Winton's entry into Organon contradicts the bearish analyst consensus.
While Winton deployed capital aggressively, two targeted company leaders sold stock at substantial levels. Fortrea CEO Thakral sold 99,869 shares at $19.16 per share for roughly $1.91 million in proceeds. The concurrent executive selling and institutional buying creates tension: Winton's quantitative models see opportunity, but C-suite executives see reasons to lock in gains. This disconnect often signals uncertainty about near-term price momentum or fundamental headwinds ahead.
