These two hard-hit stocks are poised for a comeback, says fund manager

Baillie Gifford investment specialist Ben James said CoStar and Duolingo, whose shares have been heavily punished over the past year to 18 months, have potential for significant growth. The article provides no valuation targets, recovery timeline, or specific growth estimates.

Analysis

This is a manager endorsement, not new evidence of earnings inflection. The main near-term mechanism is sentiment and positioning: a prominent growth investor’s comments may support a relief bounce in already weak names, but without company-specific catalysts the move is vulnerable to fading. Do not infer that the drawdown itself creates value.

The underwriting questions differ. For CoStar Group (CSGP), test whether property-data demand and monetization can withstand a weak commercial real-estate transaction environment, and whether investment in adjacent offerings converts into incremental revenue rather than merely higher costs. For Duolingo (DUOL), track paid-subscriber conversion, bookings and retention against the possibility that generative AI makes language-learning features easier for competitors to replicate or bundle. Those are hypotheses to verify, not claims established by this article.

Over 1–3 months, earnings, guidance and operating metrics matter more than the endorsement. Over 6–18 months, durable growth depends on pricing power, retention and profitable reinvestment. Contrarian point: investors may be treating the prior share-price decline as evidence of impaired fundamentals, but this article provides no basis to distinguish that from valuation compression—or to conclude either stock is poised to recover. No fundamental long is justified on this source alone.

Key Decisions for Investors

• Do not initiate a position solely on the fund manager’s comments. Treat any endorsement-driven rally as a sentiment catalyst, not confirmation of an earnings turn.
• Put CSGP on an event watch: before considering a long, verify organic revenue growth, customer retention, product-level monetization and the cost/return profile of adjacent offerings in company reporting.
• Put DUOL on an event watch: require evidence that paid-subscriber growth, bookings and retention remain healthy, and monitor whether AI features improve engagement without weakening monetization or raising costs.
• If either stock rallies before operating evidence improves, consider reducing existing tactical exposure rather than chasing; a sustained deterioration in reported growth, retention or guidance would falsify the recovery thesis.
