It is a bit of a concern, but they're not timing tools. You're right that over the next year or two, the market could go up or down a lot, but they are expectation tools. If you're buying stocks at really high pees and saying where are they going to be in five or 10 years, you better hope that earnings are just through the roof. Otherwise, even buy stocks though to hold in five or 10 years anymore. I mean, really, in 60, I know the average holding time was like seven years. Now, it feels like six months. if you're long-term.
