Nobody wants to be left behind, particularly as they watch their peers’ portfolios climb.

It’s that fear of missing out, says market coach Doug Hirschhorn, that can lead some investors to do some pretty stupid things.

For example, investors can over-trade in an attempt to keep up with everyone else. Equally bad, says Hirschhorn, they trade without a competitive edge.

And that’s a no-no.

So how can you make sure you’re not missing out? First, establish a game plan and trade it. Know your edge on every trade. And make sure you shift your perspective from relative to absolute–instead of focusing on others, mind your own business, Hirschhorn says.

Finally, accept the fact that there will be times when you miss out. After all, even Warren Buffett has an off day.
