Just take a look at Under Armours chart for the last 2 years
UA has gone from 36/share to 120(60 after the split) in less than 24 months. But as someone who lived and breathed that stock under another alias, I watched the stock sell off more than 5X to the tune of 10% or more, the worst being a little more than 36% in a matter of weeks! from 82 to 52 only to be at 120 less than 12 months later.
So I've seen this show before. It is all about asking yourself where is the consumer going to spend their dollars in the coming months, which companies are undervalued relative to what one can reasonably predict based on their own analysis and managements REITERATIONS of growth. Then after figuring out how much cash a company makes off their profits, compared to the valuation, one sees where one gets the most undervalued company with the least risk when discounted again government bonds.
