STMicroelectronics Shares Plunge 5.88% to March 2020 Low

STMicroelectronics (STM) shares plummeted 5.88% today, marking the lowest level since March 2020, with an intraday decline of 8.68%.

Over the past six months, STMicroelectronics' shares have experienced a significant decline of 33.9%, underperforming the broader Zacks Computer & Technology sector. This downturn can be attributed to various factors, including broader market trends and specific challenges faced by the company.

STMicroelectronics recently completed a series of share repurchases between March 31, 2025, and April 4, 2025. The company acquired 533,000 shares at a weighted average price of EUR 19.1716 per share. Such buyback programs can influence stock prices by reducing the number of shares available in the market, potentially increasing the value of remaining shares.

Grantham Mayo Van Otterloo & Co. LLC reduced its position in STMicroelectronics by 23.2% in the fourth quarter. Large institutional movements can impact stock prices due to changes in perceived demand and investor sentiment. This reduction in holdings by a significant institutional investor may have contributed to the recent volatility in STM's stock price.
