What Happened?

A number of stocks fell in the afternoon session after geopolitical tensions in the Middle East escalated, sent oil prices soaring and reignited inflation concerns. 

The Dow Jones Industrial Average fell over 1,000 points as the conflict involving the U.S. and Iran disrupted global energy markets, particularly through crucial shipping routes like the Strait of Hormuz. A barrel of Brent crude, the international benchmark, rose toward $85, stoking fears of a new wave of inflation. This spike in energy costs puts the Federal Reserve in a difficult position, as it may complicate future monetary policy decisions and delay potential interest rate cuts. The broad-based sell-off hit multiple sectors, with airline and retail stocks falling sharply on concerns of higher fuel costs and reduced consumer spending power.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On nLIGHT (LASR)

nLIGHT’s shares are extremely volatile and have had 52 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 2 days ago when the stock dropped 6% on the news that geopolitical tensions in the Middle East sent crude oil prices soaring, stoking fears of resurgent inflation. 

The price for Brent crude, the international benchmark, leaped over 6% to $82.57 a barrel amid an escalating war with Iran, which has threatened to block the Strait of Hormuz. This critical waterway handles about 20% of global oil flow. A sustained increase in energy prices could translate to higher inflation, potentially impacting consumer spending and corporate earnings. This scenario also complicates the Federal Reserve's path forward, as persistent inflation could delay anticipated interest rate cuts that investors have been counting on to support the economy.

nLIGHT is up 63.2% since the beginning of the year, and at $62.63 per share, it is trading close to its 52-week high of $67.69 from March 2026. Investors who bought $1,000 worth of nLIGHT’s shares 5 years ago would now be looking at an investment worth $1,856.
