On August 28, Coherent fell 4.91% in regular trading, trading at $281.03/share, with turnover of $76.27 million.

On the news front, the previous session saw NVIDIA's after-hours earnings report catalyze a broad rally in optical communication stocks, with Coherent rising over 4%. However, as the positive catalyst was fully priced in, the market reversed gains. While Coherent's most recent fourth fiscal quarter revenue of $2.05 billion represented 34% year-over-year growth and multiple Wall Street firms raised their target prices, profit margin performance has raised investor concerns. The stock has experienced significant volatility since mid-August, including an 11.93% single-day decline on August 18, amplifying short-term profit-taking pressure.

Within the Electronic Components sector, peers also traded lower, with Corning down 1.94% and Amphenol down 0.13%, reflecting broader sector weakness.
