No special skills required my friend just if you been in the market for a while with plenty of reading and experience up your sleeves you just know which business play ball and has potential to be multi baggers.
I don't have finance degree, sh*t at maths, just simple algebra so I work to the best of my ability with reading and simple maths.
Seem to work wonders compared to more complicated stuff.
Occasionally I becomes hubris and speculate and lose money but that sometimes is a good thing , it help me be a better investor with time.
The money I lose on speculation is chalk and cheese with the money I make from dozen of multi baggers.
