Why is HEICO Corporation (HEI) stock moving?
The news feed contains no HEICO-specific catalyst. The Heidelberg Materials items (insider purchase, Q3 results, analyst updates, CCS project cancellation, CheckProof partnership) concern a different company and were excluded. The only relevant item is a Benzinga historical-return article from Oct 30 that cites 18.33% average annual returns over five years and a $45.61B market cap. No SEC filings were found in the 45 days before the current date. The market data shows a strong run: the close rose from $297.36 on Oct 23 to $345.09 on Nov 10, about 16%. The stock dipped to $327.33 on Nov 5, then recovered to new highs, with an intraday high of $349.45 on Nov 10. Volume has been fading: the Nov 10 session traded about 308K shares, roughly 63% of the 14-session average of about 492K, despite the gain. The $327-338 zone (Nov 2-5 closes) is the nearest support, and the $349.45 intraday high is the nearest resistance. With the stock extended after a 16% run and no fresh company news in the window, the outlook rests mainly on momentum and long-term track record. Evidence is thin.

About HEICO Corporation
HEICO is a Florida-based aerospace and electronics company run by the Mendelson family. Its two groups make FAA-approved replacement jet engine and aircraft parts and repair services (Flight Support Group) and specialised electronic components for defense, space, medical and other uses (Electronic Technologies Group). It is best known for selling lower-cost alternatives to original-manufacturer parts and for buying many small niche companies. It has two listed share classes: HEI and HEI.A, which has limited voting rights.
How it makes money
Its largest source of sales is the Flight Support Group, roughly 60%+ of revenue. This group sells airlines and repair shops FAA-approved replacement parts that cost less than the original manufacturer's, along with repair and overhaul services and parts distribution. The Electronic Technologies Group, roughly a third or more of revenue, makes high-reliability parts such as power converters, sensors, capacitors and microwave components for defense, space, aviation, medical and telecom customers. HEICO adds to growth by regularly buying small companies, often paid for with its credit line and bonds, including a $1.2 billion bond sale in 2026.
