If there's one chart that frames the challenges to risk management right now, I think it's this one.
Going back 15 years, here's the rolling 6m realized correlation between the
$SPX and
$TLT as well as the correlation among stocks in the SPX.
In the "risk on/risk off" era, stocks and bonds were vastly negatively correlated. No longer. The latest reading is a positive 46%.
In that same era, stocks were consistently and meaningfully correlated to each other, reaching as high as 80% in crisis periods like the GFC, 2011 Sovereign Crisis and the Covid unwind. That's a thing of the past as well. The latest reading is 5%.
Stock to Bond: 100th percentile
Stock to Stock: 0th percentile
The correlation among risky assets is considerably lower than the correlation between risky and risk-free assets.
Many nominally different assets - utilities and tech stocks, for example - are not correlated today, but are linked to a common factor that could drive correlation in the future. As the bond market is as much a threat to the stock market as it is a flight to safety asset, the importance of finding real diversifying assets is critical.
