Correlations sometimes mean nothing at all, but there are occasions when they may provide insights that are worth watching. I've been paying attention to the correlation between bonds and stocks as it's been a helpful one to watch this year. Often bonds lead and then stocks follow a little later on.
QQQ vs TLT
The pair enjoy a 81% correlation, with TLT presently suggesting that QQQ may be ready to catch down, as it often has in 2022.
