You have to admit, this is a terrible, ugly, no-good chart of S&P movement.

It’s worth noting, though, that this is not a chart of this week’s declines, the ones currently causing people to scream at each other on TV. Rather it is a chart of the declines that occurred back in February.

Remember those? Yeah no one else does either.

The lesson? Don’t panic over stock movement. Buy good companies and hold them. And don’t watch much CNBC.
