Remember, annual inflation rate is around 3%, so anything around this is only preserving the amount of capital you have (i.e. $1000 now will be worth about the same in 10 years).
If you have extra capital, now is the time to invest in mutual funds, think of the low economy as a buyers market for stocks/bonds. Just realize you will have to "gut it out" and that this investment will make you money in the LONG RUN.
Now is not the time to try and switch money to CD's or bonds, doing so will tie up your money while the stock market re-corrects and starts to grow again (and I believe it will).
Remember, the market historically bounces back in surges, if you have money that is inaccessible you will miss these periodic growth periods.
