Some of us who have been investing for some time may feel very strongly about our stock or financial securities selection criteria.
Some of us prefer stocks that are neglected, undervalued and low-volatile.
Some of us prefer companies with growing earnings over time. We tend to think that as long as the cash flow grows, the company will do well.
Some prefer to buy stocks with good quality but also show strong momentum.
Some of us may have the sophsitication to do this well. For others, they have this philosophy but they might found their execution lacking.
Some might not be able to have the time to screen for stocks based on a particular criteria, looked through the stocks to see if the stock really passed your metrics and then process to buy and then monitor it.
Even if you are able to do that, you may not have the sophistication in portfolio management....
