(Bloomberg) -- The US corporate bond market may be flashing a welcome signal: That stocks are about to stop sinking.

That, at least, is the view from one Wall Street research firm.

Investors, bankers and pundits alike often parse credit markets for insights about the health of the economy and broader markets. And the story bonds have told lately hasn’t been great: Credit spreads -- a measure of the interest-rate premium corporate bonds offer versus Treasuries -- has almost doubled in the past year, a sign of increased worry about American companies.

Equities have gotten ugly, too, with the S&P 500 down almost 20% since its January peak.

But credit spreads are starting to move around less, which CreditSights says suggests stocks are nearing a bottom.

The bond-research firm examined the seven periods since 1998 when the S&P 500 posted the largest weekly declines, discovering that the rate of change in credit spreads peaked 42 days on average before the S&P 500 began to rebound.

When did credit-spread fluctuations peak this year? In March, more than 42 days ago. The S&P 500 has dropped seven straight weeks.

“If the historic pattern holds, investment-grade and high-yield spreads may continue to widen on an absolute basis,” Winnie Cisar, global head of strategy at CreditSights, wrote in a report Monday. “However, the rate of change in widening should decelerate in the near-term while the rate of change in equities may increase, leading the S&P 500 closer to a bottom. 

The spread on the Bloomberg US Investment Grade Index stood at 147 basis points Monday, nearing the 150 basis point level that many strategists see as the threshold where corporate-bond markets start to get stressed.

Despite higher borrowing costs and volatility that’s forced borrowers to the sidelines on many days, issuers continue to sell new investment-grade corporate bonds at a high rate -- nearly at the same pace as 2021. The junk-bond market has been hit harder as investors lose their appetite for riskier debt. New high-yield bond supply is running at just 24% of last year’s pace.
