What Happened?
A number of stocks jumped in the afternoon session after a broader market rally drove investor optimism in artificial intelligence and big tech stocks.
The S&P 500, Dow Jones, and Nasdaq all pushed higher, approaching record levels set late last year. Much of the positive momentum was linked to the technology sector, with a particular focus on companies advancing artificial intelligence, a key theme at the annual CES trade show in Las Vegas. This continued a powerful trend from 2025, when AI-related developments were a primary catalyst for the market's bull run. The upbeat sentiment was further supported by hopes for easier monetary policy from the Federal Reserve following a weaker-than-expected US Services PMI reading.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.
Among others, the following stocks were impacted:
Zooming In On Vishay Intertechnology (VSH)
Vishay Intertechnology’s shares are very volatile and have had 23 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 4 days ago when the stock gained 6.2% on the news that a broad rally in semiconductor stocks kicked off the new year, driven by continued investor enthusiasm for artificial intelligence (AI). The move was part of a wider "risk-on" appetite that saw the Nasdaq Composite surge early in the session. Investors rotated back into high-growth tech stocks, with the semiconductor industry appearing poised to anchor the market's trajectory. Market analysts noted that the bullish themes from the previous year, particularly around AI and tech, were carrying forward into the new year. This sentiment was supported by the view that the chipmaking industry would remain supply-constrained as companies continued to build out the new infrastructure required for AI.
Vishay Intertechnology is up 7.8% since the beginning of the year, but at $16.49 per share, it is still trading 13.7% below its 52-week high of $19.10 from February 2025. Investors who bought $1,000 worth of Vishay Intertechnology’s shares 5 years ago would now be looking at an investment worth $735.28.
