I once spent a fair bit of time doing regressions on every factor I could think of, vs SP500 P/E. The most explanatory factors, other than the previous year's P/E, were CPI inflation and interest rates. EPS growth, revenue growth, GDP growth, etc were all far less explanatory.
Other reasons too. Technology sector took off. Financial system innovations. Long decline in savings rate. Increase in debt leverage.
We've been in another going nowhere market since 2000, over a decade now. At some point that stagnant trend will break. Kind of like it did starting in 1980s.
Scary chart? Try inflation adjusting the increase over 35 years. The real return will look more reasonable.

While not directly attributable to this chart, bubbles are generally externally caused. It can be driven, like the housing market, by playing with the interest rates so that even with the increase in prices they are still affordable. Or it can be pent up demand, like consumer spending after WWII or the Power Generation market in the late 1990's once the EPA regulations were set.
We're going to see another surge like the 1980s/1990s, once the rules are set and it doesn't look like someone will be mucking with them.
