Every window, pair by pair

Ordered by the strength of the 60-day reading. A pair that changes sign across the columns is a relationship that has turned inside the last few months.

Methodology

Returns, not levels. Prices correlate on their daily percentage return and yields on their daily change in basis points. Correlation is scale-invariant so the mix is sound, and using changes for yields stops a level series that barely drifts from being distorted by ratio maths. Anything that pays a distribution is read on a total-return basis, so an ex-dividend gap is never booked as a market move.

A window means what it says. The set is aligned to a common calendar before any window is cut, so a 60-day correlation is estimated from 60 observations for every pair on the grid, not from whatever overlap each pair happened to have.

Named, never dropped silently. An asset whose history does not fetch is listed as not measured rather than quietly vanishing, because a missing row on a cross-asset board reads as "there is no relationship" instead of "we could not measure one". Free to cite with a link to this page.

FAQ

Which cross-asset relationships are strongest right now?

S&P 500 and VIX at -0.83, S&P 500 and HY Credit ETF at +0.82, HY Credit ETF and VIX at -0.7. Those figures are the 60-day window, measured on daily returns through 2026-08-28. A reading near plus one means the two moved together, near minus one means they moved opposite, and near zero means the daily moves carried no linear relationship.

Why do the four windows disagree?

Because a correlation is a statement about a period, not a property of two assets. A 30-day window is dominated by whatever regime the market is in right now; a 120-day window averages across several. When a pair flips sign between the short and the long window, that is the signal: the relationship the desk has been trading on has changed recently. The table of pairs shows all four windows side by side for exactly that reason.

How is the correlation calculated?

Pearson correlation on daily returns over a common calendar, so every coefficient in a window is estimated from the same number of observations. Yields correlate on their daily change in basis points and prices on their daily percentage return, which keeps a near-zero-drift level series from being distorted by ratio maths. Correlation is scale-invariant, so mixing the two conventions is sound.

Is the credit row a spread?

No, and this matters. The HY Credit ETF row is the HYG share price, not a credit spread. Never quote it in basis points. Helious publishes real high yield and investment grade OAS on the rates board.
