dmlabuda, Your first buy and sell .I could already have taken half away and riding on for free. It's not like there's only one stock to buy and sell . Buy 10,000 at .42 ,sell half at .84 ,start another stock . Most good value stocks take 6 months to a year to gain 100%.If it takes 1 week ,fine sell pay the tax but if it takes a year ,well ,it's nice to not have to pay so much tax. Your example presupposes a perfect scenario. Oil and NGas is a lot easier to swing trade with the commodity itself. USO and UNG SCO and KOLD .If that's all your here for ,why not go for something with steadier higher volume that is really volatile.
