If you want to get a 50% or 100% return on $1,000 fast (and safely) you can hunt around town for a killer deal on a used car, then flip it for a nice profit. Lots of people do this. You can too. Your only limitation is the # of times you can do it per year before you need to get a dealer's license.

If you want to make money fast in the stock market... I'm sorry but there is not fast way to make money in the stock market safely. It simply cannot be done. You can try, but you will be accepting substantial risk and will get burned badly eventually.
