Look no further, a friend is pouring down $500 a day to buy spx call every day, currently he is on a winning streak.

That's gambling I reckon, no expected returns.

I remember my professor used to say, gambling is when you don't have expected returns, while investment is that you do.

Me too am currently researching/simulating this case of gambling, looks indeed very interesting, IMO...
