>There are a few different strategies you could use to try and turn a quick profit with $20. One option might be to invest in penny stocks, which are stocks that trade for less than $5 per share. These can be volatile, so there is potential to make or lose money quickly. Another strategy might be to buy shares of companies that have recently had positive news announcements, such as an earnings beat or FDA approval for a new product. Finally, you could look for companies with high short interest levels; these tend to be more volatile and therefore offer greater opportunity for profits (or losses).
