For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it currently lacks a track record of revenue and profit. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' A loss-making company is yet to prove itself with profit, and eventually the inflow of external capital may dry up.

If this kind of company isn't your style, you like companies that generate revenue, and even earn profits, then you may well be interested in PrimeEnergy Resources (NASDAQ:PNRG). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.
