The most important factor in my investment strategy is purpose of investment. Why am I investing? What is the objective of my investment? Is it for a pleasure of seeing my money grow or is it for any important life goal like sending my child abroad for higher studies, building a nest egg that will serve me post retirement etc. Most importantly, keep an eye on your investments, check them out from time to time, and read on investment strategies and trends. But never get into anything you dont fully understand for you will certainly come up loosing in the end.
