Even though Mammoth Energy Services (NASDAQ:TUSK) has lost US$21m market cap in last 7 days, shareholders are still up 146% over 5 years

Mammoth Energy Services, Inc. (NASDAQ:TUSK) shareholders might understandably be very concerned that the share price has dropped 32% in the last quarter. But that scarcely detracts from the really solid long term returns generated by the company over five years. We think most investors would be happy with the 146% return, over that period. To some, the recent pullback wouldn't be surprising after such a fast rise. Of course, that doesn't necessarily mean it's cheap now.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 20% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
