Yesterday's pop was driven by Virgin Galactic's successful space flight over the weekend following months of delays. There's no news out today, so this growth stock is simply giving back some of the gains from yesterday.
As essentially a pre-revenue company, Virgin Galactic is extremely speculative, and investors are grasping at any piece of news to determine where the company is going. Delays this spring caused the stock to drop, and then the latest successful space flight caused shares to rise. Don't be surprised if there are a lot of ups and downs for the company as it moves closer to commercial space flights with paying customers later this year.
If you're a Virgin Galactic investor, like me, this is some of the volatility we can expect. As flights progress, the stock will likely be extremely volatile. But what's crucial will be how much revenue and profit the company can earn once it reaches maturity. That process will take years, and until then investors are in for a bumpy ride.
