In my career coaching work, one of the things I try to teach is how to spot these patterns of which way a market is going. This has some classic signs, and I can give plenty of examples of other industries in which this same pattern took place.

Examples would be appreciated. But this seems to be a case of trying to time the market and the usual objection applies; if you can time the market to within a year you can make huge piles of money. One of the contributors on HN, lsc of prgrmr.com talks about how he was calling the property bubble in the Bay area for years before it popped, and how if he had just got in at the frothy height of the dotcom bubble like everyone else, he'd still be ahead now on property, very far ahead.
