Keep Your Cool: 6 Tips To Invest With Confidence In This Turbulent Market

The S&P 500 Index dropped 56.8% from October 9, 2007 to March 9, 2009. The global financial system nearly collapsed. World trade halted. The former head of the U.S. Federal Reserve Ben Bernanke recently called September and October 2008 "the worst financial crisis in global history, including the Great Depression."

What started roughly seven years ago wasn't a normal market correction: It was an economic trauma. And while that trauma has been behind us for some time, many of the investors who lived through it can't let it go.

For them, it has become the monster under the bed. Every time the market drops even the slightest bit, they see the potential for a market crash. And if there is one thing I've learned as an investor, it's that objectivity -- not fear -- is my ally.

I've been investing for more than thirty years. Granted, I just missed the high-inflation of the 1970s. But I had money in the market on October 19, 1987. Known as "Black Monday," the market dropped 22% in a single day.

I had money in the market during the dotcom crash. And I've had money in the market during the last five recessions -- including the recession triggered by the extraordinary financial crisis of '07 and '08.

In every case, objectivity and caution were friends and fear was an enemy. And one of the worst things fear can do is mask opportunities.

For instance, the money that depression-era people stuffed in books and mattresses generally stayed there. It was never invested nor was it used to improve the quality of the lives that earned it.

Inflation hawks shunned bonds after the 1970s, yet since 1980 bonds (as measured by the Barclays U.S. Bond Aggregate Index) had positive returns in 31 out of 34 years -- a better record than the S&P 500.

Investors who avoided the market since the market crash that ended on March 9, 2009, have missed out on returns of roughly 200%.

Market corrections do occur with some regularity -- and we may be in the midst of one now. But it is unlikely that another market trauma is on our horizon. And it pains me to think that investors are losing sleep wondering if that market crash monster is under their beds.

So I put together my favorite tips on how to stay objective -- regardless of the headlines and market conditions.
