Alcoa (NYSE:AA) saw a significant increase in short interest during March, with the number of shares sold short rising 19.6% to 8.6 million. This represents 3.3% of the company's total shares outstanding and suggests growing bearish sentiment among investors on the aluminum producer's stock.

Why it matters

Short interest is a closely watched metric that can signal investor sentiment and potential future stock price movements.
