Are stories of turning a few thousands into millions by trading stocks real?
The short answer is yes, it is possible to do what these classes claim, however, it is highly unlikely. For every person they can show you that got rich using whatever so called method they are teaching, there are hundreds of people that didn't that they aren't telling you about. What I would recommend is invest in a well diversified portfolio. If you have a higher tolerance for risk then you can make some of that portfolio out of higher risk/reward investments. Maybe you pick the next Apple or Google or Netflix or whatever but that portion of your portfolio should be money that you can afford to lose in case you pick duds.
