Opendoor Technologies Inc. (NASDAQ: OPEN) saw its shares climb 5.26% on Monday, closing at $4.60, as the company completed its first full trading session as a member of the Russell 3000 index. The stock moved between $4.26 and $4.63 during the session, with volume reaching 78.32 million shares—roughly double the 65-day average of 39.07 million shares. In premarket trading Tuesday, shares were up another 0.43% to $4.62.
Index Inclusion Drives Volume
The index inclusion, which became effective at Monday's open, triggered significant rebalancing activity. FTSE Russell had announced the reshuffle on May 27, with the new roster taking effect after the close on June 26. Nasdaq's Closing Cross processed a record $334.0 billion in shares on June 26 to accommodate the rebalancing. Kevin Kennedy, head of North American markets at Nasdaq, described the Russell reconstitution as "one of the clearest tests" of the U.S. market close process.
Short Interest Remains Elevated
Despite the rally, short interest remains substantial. As of June 15, 153.7 million shares were sold short, representing 16.08% of the float and roughly 8% of total outstanding shares. The dollar value of the short position stands at $708.6 million, a large bet against a company with a market capitalization of about $4.4 billion. Monday's volume equaled approximately 51% of the short interest, suggesting the potential for significant short covering if the buying pressure continues. The days-to-cover metric currently sits at 3.9, though this could drop if trading volumes remain active.
Financial Performance and Strategy
Opendoor's inclusion in the Russell 3000 comes as the company works to prove its business model. First-quarter revenue fell to $720 million from $1.15 billion a year earlier, while net loss widened to $173 million from $85 million. The company held 3,420 homes in inventory at the end of March, down from 7,080 a year ago, with inventory value declining to $1.14 billion from $2.36 billion. Homes sold dropped to 1,921 from 2,946, while purchases fell to 2,474 from 3,609.
CEO Kaz Nejatian has emphasized a turnaround focused on speed and efficiency. "The machine is working," he said in the May earnings release, noting that old inventory has shrunk from "half the book to one-tenth" as acquisitions accelerate. He has dismissed any notion of returning to the old iBuying model.
Cost-Cutting and Operational Changes
Reuters reported earlier this month that Opendoor plans to close its India office and cut 250 jobs there, shifting work to U.S. teams with greater reliance on AI. Nejatian said the company wants operations "in person and close to our customers."
Market Context and Sector Performance
The housing-tech sector broadly gained on Monday. Zillow Group (NASDAQ: Z) rose 0.71% to $31.38, Rocket Companies (NYSE: RKT) gained 3.30% to $15.50, and Offerpad Solutions (NYSE: OPAD) advanced 1.53% to $4.62. Opendoor's performance is closely tied to housing market trends, with upcoming data releases including U.S. Case-Shiller price data, consumer confidence, and JOLTS figures expected Tuesday. Lower home prices could compress Opendoor's resale spreads, while faster sales would reduce holding costs.
The stock's 52-week range spans from $0.5267 to $10.87, highlighting its volatility. Monday's rally and index inclusion provide a fresh catalyst, but the elevated short interest and ongoing operational challenges keep the stock in a high-risk, high-reward territory.
