Birchtech short interest soars 627%

Watch: Monitor changes in short interest and settlement progress as these will dictate the stock's recovery potential.

Birchtech's short interest surged 627% to 25,549 shares, representing 0.1% of the float with a days-to-cover of 0.3. This spike marks a sharp rise from 3,516 shares previously. Despite insider buying and a recent $15M capital raise, bearish sentiment is emerging amid decelerating revenue and ongoing operating losses.

The sharp increase in short interest signals growing market skepticism, which could suppress near-term price gains despite operational progress and insider confidence.
