Goldman Sachs
Goldman Sachs' Jan Hatzius doesn't see a crash coming.
Using a proprietary model that includes the historical price data from 20 advanced economies, Hatzius found that the likelihood of a crash is "average" only.
"[O]ur broader view is that the risk of an asset market bust - especially of the recessionary variety - remains relatively low," Hatzius wrote.
We're Not In A Danger Zone
After adding in the data for the first half of 2014, Goldman analysts have noticed that the risk of a stock market crash is "back up to roughly average levels" because the further US equity price gains for 2014 have pushed the risk" higher. (That's what the red arrow is showing on the model.)
However, average is not the danger-zone just yet. In order for their to be a high risk of a crash, according to Goldman Sachs' model, the curve would have to be high above the straight gray line - aka the zero standard deviation line.
On top of that, the general consensus of Goldman research analysts is that the crash is still far off.
"Although the current expansion has already lasted longer than the median expansion, we still seem to be quite far from the inflationary overheating or financial imbalance that historically precede most US recessions," the report states.
Important Factors In Goldman's Equity Bust Model
According to Goldman analysts, the primary factors that determine equity busts are past asset price appreciation, past credit growth, and a rising investment/GDP ratio.
"[T]he single most important predictor is past equity price appreciation," the report states. "Our interpretation is that many equity busts are simply the counterpart of prior periods of strong price appreciation, and in this context it is not surprising that big moves downward are more likely when volatility is high."
However, when it comes to recessionary equity busts, Goldman looks at credit growth. In these cases, while this may seem counterintuitive, recessionary equity busts generally follow low equity volatility.
Weird? Not really.
"Our interpretation is that a recessionary equity bust is quite a different animal from a garden-variety bear market," Hatzius writes. "It is less likely to be the simple unwind of a prior big equity price increase and more likely to result from fundamental economic imbalances that involve big credit buildups, excessive investment, and periods of low volatility that fuel imprudent risk-taking."
While credit has been expanding and investment spending has been picking up, it's difficult to argue either are at excessive levels.
So while the risk is back to "roughly average" levels, there's still room for it to get scarier.
