“Just run it through a company” isn’t the whole story. You also have to qualify as a trader and file an election to use the mark-to-market rules, and then you actually have to do mark-to-market accounting.
...and if your business is really killing it, and you're also killing it in the stock market, I am certain you won't have a problem paying a few dollars to the US Gov. It's still better than other investment avenues :-)
