Welcome to the end of another week. I for one am really happy Friday's finally here.

That was some nice drop in the market yesterday, wasn't it? Are you doing anything about it? I hope not. My hope is, you have your portfolio allocated according to your current station in life and that days like yesterday are not too different from any other day.

The market will go up and the market will go down. If you've spread your risk out over various security types then you should sit tight and not worry about down days like yesterday any more than you should worry about up days where you could have made more money but didn't.

Think about that for a minute. If you're well diversified, you're not only not exposed 100% to downturns like yesterday's sell off, you're also not able to take 100% advantage of the days when the bull rages. Whenever I talk to people, young people in particular, their biggest objection to asset allocation strategies is they feel like diversifying their portfolio is akin to watering it down.
