What happened Shares of miner Ferroglobe (NASDAQ: GSM) were down 14.3% as of 1:45 p.m. EST today. The big price drop comes after the company released earnings results that weren't up to investor expectations. So what Let's start with the fact that Ferroglobe's stock is already very volatile, and sometimes the stock can move more than 5% to 10% in a given day with no news at all. So a drop this big isn't completely out of the blue. Image source: Getty Images. The small-cap miner reported a per-share loss for the fourth quarter of $0.49, with a per-share loss for full-year 2020 of $1.13. Revenue for the year was down 28% to $1.14 billion. That decline was a combination of lower sales volumes from COVID-related shutdowns and slightly lower prices for silicon metal, silicon-based alloys, and manganese-based alloys. Now what Shares of Ferroglobe have been on a tear lately, surging more than 580% over the past six months, so there is a lot of optimism baked into this stock. Keep in mind that the company has struggled to maintain profitability since it went public. Perhaps with coronavirus tailwinds easing, it will be able to get back to pre-pandemic production. But whether that turns it into a consistently profitable company remains to be seen, and the price for that turnaround is pretty high right now. So for now, it may be best to sit on the sidelines. 10 stocks we like better than Ferroglobe PLCWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
