ON Semiconductor stock surged 8.51% to $76.14 on Thursday, outperforming its peers and defying a broader market trend of losses. The sharp intraday move followed a 0.8% gap up at the open and was fueled by renewed investor interest in the company’s positioning in the AI and power semiconductor markets. Recent coverage highlighted the firm’s strategic pivot to SiC and GaN technologies, with one analyst upgrading the stock to a Strong Buy.

What Happened

The session began with ON Semiconductor opening at $70.76, up from the previous close of $70.17. The stock steadily climbed throughout the day, reaching a high of $76.34 at 4:05 PM ET before settling near that level at $76.10. The move followed recent analyst commentary that emphasized the company’s exposure to fast-growing AI data center demand and its potential for margin expansion. The stock’s performance also came amid a broader market focus on technology names with high-growth potential. Despite reporting a 3.1% year-to-date revenue decline, the stock’s rally suggests investor optimism about its long-term trajectory.

What The Data Shows

The stock’s volume of 8.3 million shares was 0.7 times the 3-month average, indicating moderate participation. It also printed one fresh 52-week low and 72 fresh 52-week highs on the same day, reflecting a mix of volatility and momentum. Options activity was skewed toward calls, with $4.9 million in call premiums traded compared to $0 in puts. The largest single options print was $2.7 million. Meanwhile, recent congressional trades included a purchase by Donald J. Trump of $15,001, $50,000 in the stock on March 23, 2026.

What To Watch

ON Semiconductor is not scheduled to report earnings in the near term. Investors will likely monitor the breadth of coverage and any follow-up analyst commentary, particularly in light of the recent Strong Buy rating and Wells Fargo’s updated price target of $95.
