Months ago, signing up Colin Powell to be the keynote speaker on the first morning of its national conference would have been (and still is) a coup for TD Ameritrade Institutional.

It is even more so, now, than it was then. Because there is a coup going on in Egypt.

A populist coup, launched by average citizens, whose voices have not been heard for their lifetimes and whose economic condition has not improved in three decades of Hosni Mubarak rule.

What difference does that make to investment advisers? Stable markets are important. Growing markets are even more important.

And less anger aimed at the American capitalist system. Powell is not just speaking on a morning when civil unrest is roiling Egypt, Yemen, Jordan and other parts of the Arabic world. It’s also the same week that the FBI is warning top executives of firms such as Goldman Sachs, JP Morgan and Citicorp that their facilities, people and operations are being targeted by Yemeni-based al-Qaeda in the Arabian Peninsula.

Who better to make sense of what’s going on, than Colin Powell?

And make it make sense for financial advisers who have to be prepared for how fast the world turns, these days.
