Zero Hedge points out this awesome chart in an otherwise kind of back-test-eriffic Stanford paper on credit-equity correlation trading:

The chart graphs 2003-2010 investment grade credit spreads (left axis) versus the S&P (bottom axis), with the size of the circles corresponding to the level of the VIX volatility index and the colors distinguishing the year of the observations.

ZH’s take:

For all who trade across asset classes, not focusing on just equity or just fixed income, [the paper] contains what is arguably the coolest time series chart looking at the relationship between credit, equity and volatility. While it will have virtually no impact on one’s trading prowess, the following correlation between CDX IG, the S&P and the VIX provides countless hours of fun gazing into the distance, as well as numerous probabilistic extrapolations into the future.

True! Also, it’s sort of a neat encapsulation of the last 7 years in the markets. If you stare into the eyes of the psychedelic correlation dolphin, you can make out (among other things):

1. A reminder of how unusually stationary SPX/CDX is over this period. The authors of the paper note:

Another important observation is that the slope of CDX.IG as a function of SPX changes over time and over different market conditions. The time-varying relationship is expected, since credit spread is fundamentally a stationary process, while the equity index is obviously non-stationary. This time-varying relationship makes it difficult to directly use the slope as the hedge ratio in the credit-index index arbitrage.

Which is why it’s a dolphin instead of an eel – you’d normally think of credit spreads as mean reverting and equity as upward drifting. But still – the noticeable overall shape/slope does drive home the fact that if you put $1 into stocks in 2003 you’d have, oh, just about $1 in 2010.

2. A puzzle on implied vol levels in crappy markets – 2009 saw lower SPX and similar IG credit spreads to 2008 but with 20-40 equity vol rather than 50-80. (Quibble with the dolphin: with most VIX readings in the 10-30 range it’s kind of hard to tell them apart.)

3. Simplistic but intuitive visual evidence for an equity/credit disconnect during the crisis (and its closing or even reversal more recently) – the dolphin’s lower fin is a reminder that the pre-crisis markets paid up much more for IG credit for a given equity level than they did post-Lehman.

The paper tells you how to follow the dolphin to riches, if you’re a big fan of data mining and love math much more than I do.

    So you’re saying when the VIX is high, and the S&P is low, CDS spreads are higher!?!?!

    And both of these things occured in 2008 and 2009?

    Okay, tuna prices have been dropping all morning, which means that everybody is waiting for it to hit rock bottom, so they can buy low. Which means that the people who own the tuna contracts are saying, “Hey, we’re losing all our damn money, and Labor Day is around the corner, and I ain’t gonna have no money to buy my son the G.I. Joe with the kung-fu grip! And my wife ain’t gonna f… my wife ain’t gonna make love to me if I got no money!” So they’re panicking right now, they’re screaming “SELL! SELL!” to get out before the price keeps dropping. They’re panicking out there right now, I can feel it.

    So credit spreads comove with both VIX (stupid measure of vol btw) or the price of risk and S&P or the inverse price of risk. That’s a shocker.
