Stewart Asset Management: AI Infrastructure Drives Lumentum Holdings’ (LITE) Potential

Stewart Asset Management, a leading investment firm, reported that its flagship portfolio delivered a solid 15.97% return in the second quarter, surpassing the S&P 500 Index's 15.20% gain. For the year-to-date, the firm's portfolio has appreciated by 5.37%, compared to the S&P 500's 10.21% increase. In its second-quarter 2026 investor letter, Stewart Asset Management discussed Lumentum Holdings Inc. (NASDAQ:LITE), a prominent player in the optical networking sector, which stands to benefit from the expanding AI infrastructure market.

The company has initiated a modest investment in LUMENTUM, anticipating a positive impact from AI-driven demand for optical upgrades. During the quarter, LUMENTUM demonstrated impressive growth, with its stock price rising 13.83% and year-to-date gains of 519.81%. Its impressive market capitalization of $79.05 billion is backed by a stock that has fluctuated between $144.52 and $1,085.68 over the past year.

Stewart Asset Management recognized the company's primary risks, which include revenue concentration and product development timelines, but ultimately believes the benefits outweigh these concerns. LUMENTUM is not among the top 40 most popular stocks among hedge funds, and despite acknowledging its potential, the firm favors other AI stocks with greater upside potential and reduced risk.
