Shares of materials and photonics company Coherent (NYSE:COHR) jumped 6.9% in the afternoon session after Stifel raised its price target on the stock, citing the company's strong position to benefit from the buildout of AI datacenters.

The analyst firm increased its price target to $275 from $235 while keeping a Buy rating. This decision followed Coherent's presentation at the OFC 2026 conference, where it showcased innovations for AI-driven networks, including advanced optical solutions. Stifel noted that the company stood as a key beneficiary of the expansion in AI datacenters. This positive outlook also came just two weeks after NVIDIA made a $2 billion strategic investment and a multi-billion dollar purchase commitment in Coherent, reinforcing investor confidence in the company's growth path.

Coherent’s shares are extremely volatile and have had 51 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 8 days ago when the stock gained 4.8% on the news that the company announced it would join the S&P 500 index.

This move, effective March 23, 2026, signaled recognition of the company's market standing and its important role in the photonics industry. The inclusion often leads to increased buying from index funds that track the S&P 500. The company’s strong position was highlighted by its critical role in providing optical solutions for AI data center infrastructure. This strength was reflected in its financial performance, with Data Center revenue having experienced a significant 36% year-over-year increase, driven by high demand for its advanced products. The news followed a period of positive activity for the company, which had recently announced new products for next-generation AI and cloud infrastructure.

Coherent is up 34.6% since the beginning of the year, but at $261.60 per share, it is still trading 12.5% below its 52-week high of $298.91 from March 2026. Investors who bought $1,000 worth of Coherent’s shares 5 years ago would now be looking at an investment worth $3,823.
