A number of stocks fell in the afternoon session after news of a potential Middle East ceasefire triggered a major shift in the stock market. For weeks, investors held defensive and energy stocks during the conflict between the U.S. and Iran.

With a peace deal being discussed, the risk of global supply chain issues decreased significantly. This caused oil prices to drop sharply, leading many traders to sell their defensive shares to lock in profits while the global situation stabilizes. Instead of holding onto traditional companies, investors rotated back into high-growth technology names. Tech leaders like Broadcom and Tesla saw gains as the market’s “fear index” hit a seven-week low. Analysts believed that a more stable global environment makes high-growth investments much more appealing than defensive industrial ones. Because of this rotation, the industrial sector trailed the rest of the market as buyers searched for bigger returns in the tech sector.

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:

Vertiv’s shares are extremely volatile and have had 35 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 15 days ago when the stock gained 3.5% on the news that markets rebounded, driven by stabilizing oil prices and reports that President Trump was considering an end to the military conflict in Iran.

According to The Wall Street Journal, the president communicated to aides his willingness to de-escalate military hostilities, even if the strategically important Strait of Hormuz remained partially closed. This news helped soothe investor concerns about a prolonged conflict and its potential to spike energy costs, which can impact industrial operations and consumer spending. The positive shift in sentiment was reflected across major indexes, with the S&P 500 jumping over 1% as oil prices retreated from their recent highs.
