What the junk bond market is telling stock market investors

Given the paroxysm of speculative activity over the past 1-2 months, we've been keeping an eye on some other markets that have had a decent tendency to provide a heads-up that risk appetite was starting to wane.

One of those is the high-yield bond market. Watching for deterioration there gives us a sense as to whether bond investors are starting to price in more defaults, which can often happen before stock investors take notice. 

One of the primary gauges for that is the net percentage of high-yield bonds that are hitting 52-week highs minus those falling to 52-week lows. If it's positive, then it's a good sign for both high-yield bonds and the stock market.

High yield bond 52 week highs minus 52 week lows

The S&P 500 has held up well when this is positive. The difference in its annualized return is stark depending on whether there are more junk bonds hitting new highs or new lows. The fact that this is still well above zero indicates a healthy junk-bond market, or at least one that buyers are still supporting.

About the only negative is that conditions have been so positive for so long, it has indicated medium-term exhaustion in the past.

What else we're looking at

  • Full returns in HYG following an extreme in new high - new low breadth
  • How that has impacted the S&P 500
  • A risk-on signal using the Risk Appetite Index shows promise
  • Part 3 of knowing what you're getting into with options
  • A Bridgewater estimate of where we are in a bubble versus the Dow Industrials
  • What happens after big intraday reversals in the S&P 500 and Nasdaq Composite

Stat Box

The S&P 500 and Nasdaq Composite both recovered from near-record intraday losses on Tuesday. For the Nasdaq, it was only the 2nd time in more than 30 years that it almost fully erased more than a 3.5% intraday decline while being within 5% of a 52-week high. The other date was January 13, 1999.
