FAST FIVE: JPMorgan Finds That Fed Has Broken The Most Fundamental Market Correlation

JPMorgan Finds That Fed Has Broken The Most Fundamental Market Correlation A few months ago investors – especially those working for risk 60/40 balanced and parity funds – freaked out when the traditional correlation between stocks and yields (or inverse correlation between stocks and Treasury prices) flipped, sliding to the lowest on record, as any hope for diversification of equity risk by hiding into government bonds disappeared.

In other words, while the low – or inverse – correlation between stocks and bonds has been one of the core anchors of modern finance, allowing cross-asset traders to diversify excess equity risk into bonds, this “basic premise” of modern portfolio consutrction theory no longer works.

According to the JPM strategist, there are several drivers: First, the unusual dynamic that stocks are doing very well at the same time that UST yields have declined.

As Beinstein (somewhat sarcastically)concludes, “the potential implications of these developments are interesting” and explains: “traditionally portfolio theory says that bonds are a diversifier for equity market investments.

This has not been the case recently, with the risk that it also remains not the case if/when there is an equity market selloff.” Translation: in the next crash, everything will go down at the same time and there will be nowhere left to hide.
