People like you who engage professionals like us to help them manage their personal finances typically own stocks, stock funds and ETFs.

But barely half of America acts like you. According to Gallup (May 24, 2017), the number of Americans holding stock has declined from 62 percent before the 2008 credit crisis to about 54 percent.

The decline has occurred across all generational groups — except one. Can you guess which one? Perhaps the millennials? Gen X? Baby boomers?

If you guessed any of those, you’d be wrong. Those who have increased their stock holdings over the past 10 years, according to a recent Gallup poll, are post-retirees — those in their late 60s, 70s, and even 80s and beyond.

What’s different about them? In a word, experience. They remember the crash of 1987, the recession of 1994 and the tech bubble that burst in 2001. They remember 9/11 and the credit crisis of 2008. Having experienced all those events, they learned not to panic during such times but rather to wait for the downturns to run their course.

Post-retirees have the right perspective.

But others sold their investments during the 2008 credit crisis and have not reinvested. Nothing has convinced them to return — not even the sustained run-up in stocks since 2009.

Sadly, younger people have stopped investing in stocks in greater numbers than their older counterparts, so they are missing the opportunities stock market investing presents.

Stock ownership has declined 11 percentage points among 18- to 29-year-olds — from 42 percent before the crisis to 31 percent after the crisis.

Stock ownership by men has declined at a greater rate than women, the Gallup survey found.
