If a stock goes down in the short term, investors that are able to withstand the red days could see the big rise they expected when first buying into a company. If a stock goes up, then investors could see massive returns if they are able to resist the temptation of selling at smaller gains.

The second is a company that could continue to see massive gains over the next few years as the world moves towards sustainable energy.
