11. HEICO Corporation (NYSE:HEI)

Fisher Asset Management’s Stake: $106 Million

HEICO Corporation (NYSE:HEI) has been a core holding of the 13F portfolio of Fisher Asset Management for many years, stretching as far back as early 2014. Back then, Fisher’s stake in the firm consisted of 94,000 shares with an average price of $29 per share. Through the coming quarters, Fisher added to this stake, growing it to nearly 4 million shares. Since then, however, this holding has been trimmed, and presently accounts for only 0.14% of the 13F portfolio of the fund. In the fourth quarter, the fund increased its stake in HEICO by 13% compared to filings for the previous quarter. Since 2014, HEICO has featured in every 13F filing for Fisher Asset Management except for the third quarter of 2017.

Based on a careful analysis of Fisher and his statements on companies like HEICO Corporation (NYSE:HEI) over the years, it seems that Fisher carefully plans his investments in aerospace and defense firms. For example, in 2023, just after the resumption of hostilities in the Middle East, Fisher underlined that investors often overestimated the bullish impact of wars on defense stocks. He also highlighted how the defense sector included few pure-play weapons firms, and more hybrid companies that also offered commercial aerospace products. This is important because Fisher had previously said that in the defense world, opportunities existed in smaller or diversified suppliers, not only the largest prime contractors.

HEICO Corporation (NYSE:HEI) provides aerospace, defense, and electronic related products and services in the United States and internationally. It offers jet engine and aircraft component replacement parts, thermal insulation blankets and parts, renewable/reusable insulation systems, and specialty components and assemblies.
