Tail dependence
There is a saying in finance that in times of stress all correlations go to one. While it shows that the financial community uses linear correlation to describe any measure of dependence, it can also serve as motivation for the next measure of dependence, known as tail dependence.

Subject: Re: Probabilities
“If a decline in stocks occurs in the U.S., it will happen in Europe. If they get it in Europe, it will happen in the emerging markets. Another argument being made is that there are places to hide when this type of correction comes. I don’t think that’s right, either. You are going to see ALL CORRELATIONS GO TO ONE [emphasis mine]. Once you get into a steep decline, not a 3%, 4%, 5% garden-variety decline but something deeper, liquidity becomes the issue. Even though smaller markets have more flows than they did five or 10 years ago, they have higher beta. When people start to reduce risk, that’s what they’ll sell. ”

Yes, there is some saying, but I don’t remember it exactly….something like “In a crisis, all correlations go to one.” Meaning that both hedge and asset move in the same direction instead of opposite directions. That’s what did LTCM in.
Why the common expression “all correlations go to one” may be overstated

Since 1987, the term “correlations go to one in times of stress” has become axiomatic in financial markets.  But does research actually back up his common assumption?

Rationale on Antitrust Is Put in Play
In a crisis, all correlations go to one.
And not only with asset prices. It also could apply to the relationships at the heart of antitrust regulation: between consumers, labor and owners.

During a period of market upheaval, as a Wall Street saying has it, “all correlations go to one.” Investors panic and sell many different types of assets at the same time.

All Correlations Are Equal to One
Or, as Charlie Kindleberger used to say back around 1980: in a financial crisis everything moves together—all correlations are one.

Of course, maybe we should just have people pay out of current tax dollars.  That avoids the asset problem, but introduces another one.  Remember, in a financial crisis, all correlations go to one.  That means tax revenues, too.  Any potential source of funding for retirement will be severely undercut by a financial crisis.

In times of intense stress, it’s said that all correlations go to one. That means that no matter what an investment’s historic performance is or what its own unique characteristics are, it will get pulled down like everything else.
