Shares of this digital medical platform jumped more than 100% overnight. Here’s why

Shares of the digital medical platform, Doximity, experienced an overnight surge, jumping more than 100%. The cause was Doximity CEO Jeffrey Tangney's bold comments on the platform's new AI search tool. During the company's first-quarter fiscal 2027 earnings call, Tangney stated that the product yields more than ten times its operational costs per search. He further explained that, over time, the AI search's unit economics are expected to improve as models become more efficient.

Doximity shares opened at more than 130% in premarket trading, later settling at a 55% increase. Analysts believe that these impressive gains have not yet been incorporated into the company's strong financials. In the first quarter of fiscal year 2027, Doximity reported revenues of $156.6 million and adjusted EBITDA of $74.8 million, both exceeding market expectations.

Furthermore, the company boosted its full-year revenue forecast by $6 million, or 5%, to between $671 million and $681 million. However, analysts argue that this increase likely does not include the significant potential from the expanding AI commercial pipeline, which Tangney highlighted as a "surprise and upside" for the company.

Tangney asserted that the AI search tool is not only boosting profitability but also expanding the total addressable market for Doximity in healthcare and pharmaceutical sectors. Michael Cherney from Leerink Partnerships echoed this sentiment, stating that the AI search could lead to attractive long-term margins as the market size grows.

Despite the positive impact on Doximity's stock, the sudden rise is detrimental to those who had shorted the shares. Approximately 17% of shares available for trading were sold short before the earnings results, and their forced unwinding likely intensified the stock's surge.
