StockStory Backs GitLab (GTLB) Despite Losses; Questions Opendoor, ACV Auctions

Investment research firm StockStory on May 29, 2026, endorsed GitLab (NASDAQ:GTLB) as a buy despite its losses, arguing the company is investing aggressively to secure market share, while flagging Opendoor (NASDAQ:OPEN) and ACV Auctions (NYSE:ACVA) as stocks to avoid. GitLab, a DevSecOps platform, recorded a trailing 12-month GAAP operating margin of -7.4% and trades at 4x forward price-to-sales. The firm highlighted its remote-first development model as a strategic advantage. Opendoor, a technology-driven home buyer and seller, posted a -9.9% margin and trades at 233.2x forward EV/EBITDA. ACV Auctions, an online used-car marketplace for dealers, also reported a -7.4% margin, with a valuation of 11x forward EV/EBITDA. Both companies face intensifying cash burn and lack clear near-term paths to profitability, raising sustainability concerns for investors.
