2 Optical Stocks to Buy After Tuesday's Selloff
Lumentum (LITE) and Coherent (COHR) shares fell 9.9% and 12.8% respectively on August 18, despite strong earnings reports. Lumentum's revenue doubled, with Q4 at $1.01B and FY at $3.01B, while Coherent reported record Q4 revenue of $2.05B and FY revenue of $7.12B. Both companies guided higher for future quarters, but investor concerns about AI demand led to the selloff.
