Investment grade bonds haven't been a great investment
The WSJ pointed out that one of the few markets that has been struggling is investment-grade bonds. That certainly has been the case, as the 10-day average of the percentage of advancing bonds is just now trying to curl up from a very oversold condition.

A recent reading near 40% is one of the lower ones in 15 years.

As far as a signal, though, it's been only so-so. The LQD fund did tend to rise going forward but its average return was a bit below average. The biggest positive was that these signals triggered when coming out of oversold conditions, so forward losses tended to be limited.
