Ups and downs: Coherent's stock price (past two years)
Since reaching an all-time high of nearly $330 in January 2018, Coherent's stock price has nearly halved in value - despite the laser firm continuing to post solid-looking financial results. Investor concern appears to surround the stand-off between Apple and Samsung, amid weaker demand from consumers for ultra-expensive smart phones. Coherent's lasers are critical to OLED display production, an area still dominated by Samsung. Image: nasdaq.com.
