Lumentum stock tumbles as year-end tech pullback hits AI optics names
Lumentum Holdings shares fell 4.1% to $374.87 by midday Monday, outpacing declines in tech benchmarks and optical peers. The stock swung between $390 and $364.50, retreating from last week’s 52-week high. Coherent and Ciena also dropped, but by less than Lumentum. Investors trimmed exposure to AI-linked names ahead of the New Year, with trading volumes thin and markets watching Fed minutes and jobless claims.
