I was waiting for my friend in a bookshop. I picked up a book Which is called "the little book of investing" or something. Which explains the basics of investing. I found out in the book that there are sometools which are called stock screeners. I search in internet and found out such tools. I made a ranking and picked the top stocks in my list. I then used finance.google.com web site to test my strategy. I created a porfolio there and started to watch the developments for 1 month.
I used different methods when constructing this porfolio. I first used Moder Porfolio Theory and historical prices (instead of expected prices) to build the porfolio allocation.
I found out later that my return would be higher if I would allocate the porfolio based on the market capitalization instead of the MPT allocation. So I though that I need to do anything here to find out more about the porfolio allocation strategies.
