When I started equity investing, I would always come in 100 percent or all-in in one particular stock.

But in some instances I had to cut my losses painfully, just so to prevent further eating up my capital.

The old adage tells us not to put all your eggs in one basket. In other words, there is a need to diversify your portfolio. Several factors come in:

2. Your risk tolerance will also apply. Whether you can stomach daily paper losses or you are satisfied with small returns offering low risks.
