We encourage people to maintain their long term investment objectives that meet their personal risk profile. Do not switch when the porridge get’s “too hot” or “too cold”, as it will usually leave you with a bad taste in your mouth.
The following excerpt from the American Association of Individual Investors is a great example of this:
The S&P 500 bottomed at 677 on 3/09/09, the end of a 17-month bear market in which the stock index fell 57%. A weekly survey of stock investors indicated 70% of them were bearish as of 3/04/09, the highest bearish measurement ever recorded by this study.
Stick to your plan!
