If you wanna talk about methods...
LOL!
here's my opinion...
1. if market newbie.... keep money in bank.
paper trade la...
U will learn much more
Trust me deep deep...
U is no pondan if u do paper trading/investing one...

2. Focus is more important.
Do a proper journal..
posting in a forum... err....
3. 10 stocks? 20 stocks?
See a simple question... which goes back to point 1.
How would you know if doing <5 might be a better option?
And if that's the answer....
Imagine the time needed to find out this answer...
Imagine the monetary ...
in terms...
a) the case of lari the ayam
perhaps <5 could see one making 30% a year....
b) lost money... ahImagine... spending 5 years...
trying to make money all those 5 years using one's weakest capability....
imagine... if lose money? how?
imagine if the losses turns into debt?
money hor...
no try try one laaaa....
respect the money hor....
money nowadays susah cari one....

In short, the better u are in choosing, the less stocks u have.
