Why Did QuidelOrtho Soar 11.07%? Short Interest Surges 27.6%

On April 14, 2025, QuidelOrtho's stock surged by 11.07% in pre-market trading, marking a significant rise that has caught the attention of investors and analysts alike.

One of the key factors contributing to the recent surge in QuidelOrtho's stock price is the increase in short interest. As of February 15th, the short interest in QuidelOrtho totaled 4,350,000 shares, representing a 27.6% increase from the January 31st total of 3,410,000 shares. This rise in short interest suggests that there is growing speculation and potential for volatility in the stock's price movements.

Additionally, UBS Group recently boosted their price target on QuidelOrtho from $43.00 to $45.00 and maintained a "neutral" rating on the stock. This adjustment in the price target reflects a positive outlook on the company's future performance, which may have contributed to the recent upward trend in the stock price.

Despite the recent market turbulence and worsening liquidity conditions, the performance gap between high- and low-liquidity stocks has remained surprisingly stable. This stability in the market may have provided a favorable environment for QuidelOrtho's stock to rise, as investors seek out opportunities in the midst of market volatility.
