There is a smaller subset of the world of mutual fund investments that are actually genuine risk managers. They are geared simply toward the belief that avoiding losses is far more important than pursing high returns. During tougher economic times and the recent global bout with recession, many mutual funds and major market indexes in general sank heavily.
If your portfolio had a fund that strangely suffered much less damage than the rest, or even managed a small profit, then you invested into a risk manager. In 2008, the market crashed in an extreme manner, not allowing most risk managers to survive. So, if your portfolio produced a survivor, then that fund is obviously a great investment strategy to pursue further.
You can be an aggressive or a passive investor. Yet understanding and exploring risk management is merely some relief for your own blood pressure. And on the other side, it could generate returns that you would not have expected originally.
Whatever path you take on the market, do not forget the basic rules of how to invest viably:
Chasing alpha means trying to outperform benchmarks and high risk assets; so if you do, be prepared to pay heavily during downturns. You can rarely beat the market at its game, so diversify instead of trying emptily. Always be careful.
Though most funds are simple in their ultimate goal and the roads they take (tracking individual indexes), things can quickly become too complex for a beginner to understand and wade through effectively. Be wise with your investments.
