- Opendoor Technologies Inc. NASDAQ:OPEN traded up 1.6% at $4.37. Volume came in at 171.46 million shares.
- Turnover on Friday came in at about 4.75x the 65-day average, representing around 21% of the public float.
- Opendoor was named in FTSE Russell’s final additions list for the Russell 3000, to take effect after the U.S. market close.
Opendoor Technologies Inc. NASDAQ:OPEN saw trading volume top its most recent reported short interest on Friday as the Russell 3000 rebalance brought a surge in activity to one of the most shorted names in housing tech.
Opendoor finished the session up 7 cents, or 1.6%, at $4.37, with a range between $4.20 and $4.51. Volume hit 171.46 million shares, well above its 65-day average of 36.11 million, at 475%. MarketWatch puts the company’s public float at 806.03 million shares and short interest at 153.72 million shares, numbers last updated June 15. In after-hours trading, shares slipped 0.9% to $4.3308 on volume of 31.19 million. MarketWatch
Friday’s closing price saw around $749 million in stock trade, about 18% of the company’s market cap. That’s also roughly 1.12 times the short interest on record. But the day’s price gain didn’t match the size of that volume. The action felt more like mechanical index flows than buyers or sellers making a call on the company itself.
Russell 3000’s final add list from FTSE Russell, dated June 26, had “OPENDOOR TECHNOLOGIE (A)” with ticker OPEN in the real estate sector. LSEG is putting the new index changes in place after the U.S. close on June 26. They go live with the U.S. market open June 29. LSEG
Opendoor told investors back in May that getting into the Russell 3000 usually lands a stock in either the Russell 1000 or the Russell 2000, along with various growth and value style indexes. That means more benchmarked funds can hold the stock, but it doesn’t move the needle on revenue, margin or cash use. Opendoor Technologies Inc.
FTSE Russell said investor assets tied to Russell U.S. indexes total about $12.2 trillion. The firm said the June 2025 reconstitution saw $217.2 billion in volume at the close, making it one of the top trading days this year. LSEG
The Nasdaq Composite dropped 0.24% on Friday as total U.S. exchange volume rose to 30.1 billion shares, topping the 20-session average of 23.1 billion. That gave the Opendoor trade more context. Reuters
Opendoor’s numbers aren’t getting easier. First-quarter revenue fell to $720 million, from $1.15 billion the year before. The net loss widened to $173 million, compared with a loss of $85 million last year. The company bought 45% more homes compared with the fourth quarter, ending the period with 3,420 homes in inventory. Opendoor Technologies Inc.
Opendoor CEO Kaz Nejatian said in May, “The machine is working,” as the company highlighted stronger acquisition cohorts and improving resale speed. Opendoor said it expects second-quarter revenue to climb about 25% from the first quarter, with adjusted EBITDA close to breakeven. Opendoor Technologies Inc.
Monday’s open is set to measure how much of Friday’s volume was just index cleanup for investors. The stock still carries a big short base and plenty of float, now with new index demand in play. But the big signal for price will have to be margins and how many homes get bought.
