Gravity wins: GoPro stock plummets 10%

Still too expensive? The stock trades at more than 40 times 2015 earnings estimates, a very rich priceespecially for a company that critics view as a fad.

“Rubik’s cube and Cabbage Patch Kids had huge Christmas sales once too,” wrote GamindeMedellin, a trader on StockTwits.

There is growing competition. Although GoPro is clearly the leader in the wearable camera market, Sony (SNE) debuted the Action Cam FDR-X1000V at the CES show in Las Vegas last month. Some have dubbed that a GoPro killer.

Polaroid (yes, it still exists) has a new product called the Cube. It’s a smaller and cheaper action camera alternative to GoPro’s Hero line of products.

GoPro enthusiasts often film themselves falling from great heights. Now the stock price is doing the same thing.
