Risk based stock selection
If you have a portfolio of 1000 stocks, there are 5 key decisions that one needs to take:
Buy to Open
Sell to Open
Buy to Close
Sell to Close
Do Nothing
In a quant based strategy like the one I have been working for the past few months , the signals help me get on to the position. However, there is a catch. As you get on to the position based on external asset price movements, you have to look at something relating to the portfolio, which is RISK.
