I was once building a new computer. I got 2x 32MB memory sticks, for something like a grand. When I bought there were a few places listing them for an impossibly low price, like $100. A month or two later, EVERYONE was selling them at $100.

The average investor shouldn't try to outsmart the market. But, if there are indications the price of hens is going to dip dramatically, it may be worth delaying that big purchase.
