It depends on what your goal is. I'm learning day trading and watching guys making an average of a couple grand a day trading penny stocks. That's my goal. Its definitely not bad especially if you have a career and doing it on the side.

You were just lucky is all.

(If it were possible to consistently return more than 15%-20% just by investing in Stocks, why would ANYBODY ever go into business actually running a business to earn maybe 5% more than that, on average?)

If you bought and levered up THI because you said "THI is an excellent candidate for an inversion merger deal for some US corporation trying to lower its taxes" and levered up because your portfolio analytics said that was the right thing to do, it is completely excellent. If you bought THI because you like their donuts and levered up because it is fake money anyway, it's nothing. Which is closer to the truth?

Just don't get the idea that you could consistently do this in the real world.

yes

Ok so I went to this website called updown.com which gave me a "fake" portfolio with 1 million to manage. I made a return of 62% in a year. This looks increadinle to me really !!! My best stock was THI which grew 44% in a year ! I learned the basics of stock investment and diversity etc... I want some opinions because my goal in 5 years is to invest 100K in the stock market because I know it's my destiny... I feel it since my 3rd grade when I learned about it.
