What Happened?

A number of stocks fell in the afternoon session after President Trump declared the Iran ceasefire "over" and threatened fresh strikes, pressuring the commercial-aviation supply chain as oil prices surged. 

Commercial aerospace lives or dies on airline health, so the read-through from a crude spike is quick and negative. When jet fuel prices soar (WTI rose 7.1% to $75.41) carriers see margins compress and often respond by deferring aircraft deliveries and trimming capital plans, which threatens the order books and cash flows of manufacturers and their parts suppliers. A broad risk-off tape, with the Dow off more than 1% and yields climbing, adds further pressure to a capital-intensive, long-cycle group. 

While defense-oriented names can benefit from rising conflict, the commercial side of aerospace is tied to travel demand and airline profitability, both of which weaken when energy costs rise and geopolitical uncertainty deepens.

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

Zooming In On HEICO (HEI)

HEICO’s shares are somewhat volatile and have had 11 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 biggest move we wrote about over the last year was 4 months ago when the stock dropped 12.2% on the news that it reported fourth-quarter 2025 earnings that, despite beating headline estimates, contained underlying weaknesses that concerned investors. 

While revenue grew 14.4% year-on-year to $1.18 billion, narrowly beating expectations, investors focused on several negative details in the report. The company's GAAP earnings per share of $1.35 only surpassed estimates due to what the company called "a discrete income tax benefit from stock option exercises;" without it, the company would have missed expectations. 

Furthermore, Adjusted EBITDA of $312 million fell short of Wall Street's consensus. Another key concern was a decline in cash generation, with the free cash flow margin dropping to 14% from 18% in the same quarter last year. The sharp stock decline suggested investors were more worried about the lower-quality earnings beat and weaker cash flow than the top-line growth.

HEICO is up 4.9% since the beginning of the year, and at $345.55 per share, it is trading close to its 52-week high of $358.04 from January 2026. Investors who bought $1,000 worth of HEICO’s shares 5 years ago would now be looking at an investment worth $2,477.
