You can, undoubtly, i made some good money on AMD a decade ago...
Since, i abandonned the US market because i live in the Eurozone and i dont want to bother with the $/ parity, but i m still trading such a dreadfull stock in the EU and it works very well.
Such stocks require a dynamic management if you want to hold a long term position so you have to sell and buy back to take advantage of the volatility that otherwise will kill you.
If he wants to hold his position he has to be here every day , sell if the trend is bear, and then buy back a biggest quantity of stocks for the same amount of $ , if the trend is bullish he has to try to sell at the higher points and buy back on recoveries, that s the only way to win with very volatile stocks, of course a step further would be to not only sell but to short sell on the same row before buying back twice and be long again, but i wont advise one to do such an agressive strategy if he has not a formal training and accurate knowledge of decision tools.
Jeebus. Might as well trade bitcoins instead. At least there's no tax on the transactions (or at least you can get away with not paying any).
