Samsara, you seem very book-smart guy, go ahead and implement all theories in your life but I believe it is a common sense.

Stock market is a pretty much a gambling. Right now, stock market is in record low. I don’t know when I gonna see this less than 8000 Dow Jones. That means you can buy world largest banks and financial institution’s stocks in pennies. I don't suggest buy stock from bankrupt comapanies.

If you put little money on it, its not gonna hurt, it may turn out to big money 1-2 years later.
