Week move measures change from June 26 close through July 2 close.

The detail to watch is Gibson’s planned sales. Gibson, who co-founded the company and already said he won’t seek another board term after June, filed for possible sales of 100,000 shares on both July 1 and July 2, according to Form 144 filings. In April’s update on board changes, CEO Najat Khan said, “We remain focused on continuity and long-term value creation at Recursion.” Recursion Pharmaceuticals, Inc.

Form 144 gives notice of a planned sale, but doesn’t confirm all planned sales were made. The July 2 notice did show a July 1 sale of 100,000 shares at $366,630.37 under sales from the prior three months, plus 640,440 shares sold during that time for roughly $2.13 million in gross proceeds.

Form 144 filing on July 2 signals sale100,000$374,500 total market valueEquals about 0.31% of Thursday’s traded shares
July 2 notice lists sales in past three months640,440Gross proceeds near $2.13 millionComes to approximately 0.12% of shares out

That stands out since the flagged insider sales are smaller than the volume the market saw. Recursion listed 524.68 million shares outstanding. On Thursday, 32.68 million shares traded hands. The combined 200,000 shares from the two insider disclosures add up to just 0.6% of Thursday’s trading.

Short interest is the big story here. MarketWatch listed 184.02 million RXRX shares sold short as of June 15, making up 39.11% of the float. That figure is 5.6 times Thursday’s trading volume. So for next week, what matters more than an insider filing is whether this crowded short sees big trading action.

The balance sheet is another part of the rally story. Recursion reported $665.2 million in cash, cash equivalents and restricted cash as of March 31. The company also said its cash runway goes into early 2028 even if it doesn’t raise more funds. With a market cap around $2.02 billion as of Thursday, that cash pile makes up about a third of Recursion’s equity value.

The company is still burning cash. First-quarter revenue was down to $6.5 million from $14.7 million last year. Net loss narrowed though, down to $117.5 million from $202.5 million. Cash operating expense dropped to $85.1 million from $120.2 million. “We are seeing strong momentum and execution across our portfolio,” Khan said in May. GlobeNewswire

Looking at the week ahead, Nasdaq’s normal session starts again on Monday, July 6, open from 9:30 a.m. to 4:00 p.m. ET. On company news, Recursion is keeping its timeline: the REC-4881 regulatory update and more REC-1245 Phase 1 dose-escalation results remain expected in the second half of 2026.

  • Patterson-UTI (PTEN) Slides After Q1 Beat; Water Solutions Tops Peers
    July 3, 2026, 7:05 PM EDT. Oilfield services names turned in uneven Q1 results. The group beat revenue consensus by 3.8% but still averaged a 14.3% drop in share price. Patterson-UTI (NASDAQ:PTEN), with its 135 advanced rigs, posted revenue of $1.12 billion, down 12.7% over last year but 1.2% above analyst targets. PTEN delivered beats on both EPS and EBITDA, yet shares tumbled 19.9% to $8.66 after earnings as investors stuck to worries over low commodity prices. Select Water Solutions (NYSE:WTTR) led on revenue, topping estimates by 6.8%, even as sales dropped 2.3% year-on-year. Oil price swings, tough competition, and the energy transition add to the sector's cloudy near-term picture.
