AI datacenter spending has turned optical networking into one of 2026's hottest trades, but the three biggest U.S. optics stocks have performed so differently that picking the wrong one meant leaving triple-digit gains on the table.
Every so often, a stock quietly climbs its way into the upper ranks of the market's leaderboard without attracting the attention its performance deserves. Lumentum Holdings NASDAQ: LITE is one of those names.
