Why COHR stock is up today

COHR stock rose 5.74% to $291.29 in early trading, driven by a broader market shift in the optics and semiconductor sector. The move followed a sharp selloff in Applied Optoelectronics after the company announced a $600 million equity offering. This capital raise triggered a broad pullback in AI optics stocks, but the resulting market rotation appears to have benefited COHR, which opened with a 3.5% gap up and continued to climb throughout the session.

What Happened

COHR opened at $285.05, up from the prior close of $275.49, and reached a session high of $291.71 at 9:45 AM ET. The stock traded within a range of $282.50 to $291.71, with volume so far at 0.6 million shares, which is 0.1 times the 3-month daily average. The broader market saw weakness in several high-profile tech and memory stocks, including SanDisk and Seagate, which contributed to a general decline in the chip sector. However, COHR bucked the trend, likely due to its relative strength in the optics space and its position as a less direct casualty of the Applied Optoelectronics offering.

What The Data Shows

COHR has a market capitalization of $56.7 billion and a price-to-earnings ratio of 66.9. The company reported revenue growth of 22.5% in the trailing twelve months and maintains a net margin of 11.3%. The stock has traded between $85.94 and $440.00 over the past 52 weeks. Recent insider transactions include two sales by the CFO, totaling $1.3 million in the last 90 days. Congressional trades show mixed activity, with Rep. Ro Khanna buying and selling small positions in the last month. On the options front, unusual activity included $3.1 million in call premiums, with the largest single print at $2.0 million.

What To Watch

COHR does not have an announced earnings date in the immediate future. Investors should monitor the broader chip sector for signs of stabilization and watch for changes in coverage or sentiment as more analysts weigh in on the optics trade.
