The maintained Outperform rating by Northland Capital Markets indicates that they still believe Quantum's stock will outperform the market in the short term. However, the lowered price target from $6.00 to $2.25 suggests that they have adjusted their expectations for the stock's potential upside. This news is likely to have a positive impact on Quantum's stock price in the short term, as it shows that analysts still have confidence in the company's performance, despite the lowered price target.
