I got an idea for 2008, does it work? please comment

If Dow Jones increases 200 points in a day, before the market ends, I will sell $10K index fund (fund A for example) that is close to Dow Jones and buy bonds or money market. Then I wait...
some days later, Dow Jones drop 200 points, I will buy $10K fund A back. After this two transaction, my net worth may not increase, but I own more share of fund A now.

Then repeats...

Condition: Fund A transaction has no cost (usually it is in retirement account), Fund A is not junk fund, so I will not end up with millons shares of junk.

Does this work?

The best part is that I will always be happy regardless market is up or down.
