Good question!

The median price to sales ratio on the S&P 500 is 1.5 so that would give GPRO a stock price of $14 on 1.5 billion in sales.

Also, at a 10% net profit on that sales, the price per share on an Earnings Per Share ratio of 20 would be $19.

There are other metrics showing they are undervalued but the price largely performs on whether they are living up to expectations, which they have been falling at recently. It does make it so they are setup to post year over year growth numbers as well, so all things point to a better stock performance if they do have a bit of a turn around.

Thanks for coming by
