Gunter Loffler, of the Department of Mathematics and Economics in the University of Ulm (Not “ummm”, Ulm, in Germany. I didn’t know where it was either.) published a recent paper postulating a connection between the construction of world’s tallest skyscrapers and financial market returns. His thesis is, essentially, that periods of time when humans have the hubris (and commercial real estate funding) to build massive skyscrapers are the same periods when stock prices become overvalued.
Looks like he’s actually on to something. From the abstract:
This papers shows that construction starts of record-breaking skyscrapers predict subsequent US stock returns. In the three to five years after the construction of a record-breaking new skyscraper began, per annum stock market returns are around 10 percentage points lower than in other years. The predictive ability is significant and relatively stable.
In fact, the predictive power of his “skyscraper index” (my phrase, not his) actually beats more commonly used metrics. Again, from the abstract:
It exceeds that of alternatives such as the prevailing historical mean, predictions based on dividend ratios, and recently suggested combination forecasts. The findings are robust against a wide range of specifications. Further analyses show that tower building also predicts international stock market returns.
If I’d have just known that it was as simple as selling stocks when the construction for new world’s tallest skyscrapers was begun…

I’d add to the list the headache of bank capital and liquidity levels coming into question since many financial institutions maintain large Treasury note positions. Municipalities, pension funds and other large institutional investors are also required to hold certain percentages of their pools in high quality assets, so would feel the effect of deteriorating credit quality (not to mention the painful price markdown.)
