What can I invest 1500 in?

If you really want to invest in a way that achieves excellent growth over the long term, invest in one or two good companies that consistently grow their dividends. Dividends should be reinvested. General Electric (GE) might be a good place to start. The bottom line, seek out quality companies and reinvest dividends and you should do very well.

Try some ETF instead of stocks.

Tesla stock. It's the best option if you are looking long term, honestly it's great because it's the future. If you are looking to make like 200 dollars in a matter of days them go on etoro and invest all 1500 in for example google or facebook(the big ones) before they announce their quarter. Normally their quarters are really big and if not the you can only loose around 20-100 dollars but you can gain a lot.
