They start with a serious analysis, but some parts of their claims strike me as silly.
For instance, they say:
To believe that the market is overvalued, you have to believe that the risk premium, once irrationally so large and getting rationally small, will become irrationally large again.
Ignoring the hypothesis that stocks are overvalued because earnings/dividend forecasts are too high, I see two reasons to suspect that a rational investor might think the risk premium is currently too small.

The hypothesis that it will go away soon doesn't imply you should just buy stocks. It implies you should also sell short bonds, as the change could happen entirely by an increase in interest rates.
The most striking feature of their conclusions is that it implies that there should be an incredible reward to creating new companies. 36000 on the DJIA implies that companies are worth about 20 times the capital apparently required to create them. This seems to imply either that there are much larger costs that don't get accounted as book value than economic analysis normally assumes, or there are returns to putting capital into creating new companies approaching 1900% that people are irrationally(?) ignoring. This would seem to hint that it is more likely that interest rates are too low than that stocks are too low.
P.S. - I'm currently betting the market will go down over the next month or two, but wouldn't be surprised if the bull market resumes this winter and continues until the baby boomers retire.
