What end of Great Moderation era means for stocks: Chartbook

The era of "Great Moderation", where bond yields and stock prices are positively correlated, could be over. But it could be entering what one strategist refers to as "the temperamental era", moving toward uncertainty and volatility in markets.

Charles Schwab Chief Investment Strategist Liz Ann Sonders joins Yahoo Finance Reporter Josh Schafer for the latest edition of Yahoo Finance's Chartbook, to discuss these periods in the market and the impact they can have on markets in both long and short-term periods:

"There may be a bit more volatility than what we are used to longer term, but let's hope, and probably not to the same degree that we saw it last year. We've been in this unique cycle, it's often said that the Fed takes the escalator up when they're hiking rates, and the escalator down — this one's been at the opposite. They took the elevator up, and I guess they'll take the escalator down. But because they are operating on the data dependency, and they are simultaneously doing QT [quantitative tightening], that has been sort of a force behind higher volatility in the fixed-income side, even more so than on the equities side.

RACHELLE AKUFFO: Now the era of great moderation, where bond yields and stock prices were positively correlated, is likely in the rearview mirror, at least according to our next guest. For a deeper dive into this chart, we're joined by Liz Ann Sonders, Charles Schwab chief investment strategist, alongside Yahoo Finance's Josh Schafer as well. Great to have you back on the show here. So Liz Ann, for people who aren't familiar with this phrase, low inflation, low volatility, how does that tend to show up in bond yields, as well as in the stock market prices?

LIZZ ANN SONDERS: Well, specific to what we now generally think of as the great moderation era, which was from the late 1990s up until the pandemic, that was a '22, three, four-year era where you were essentially in disinflation the entire period of time. You were in the latter part of the long, secular move down in interest rates, certainly long-term bond yields having come down.

And it was a period when because inflation wasn't much of a concern, the moves in bond yields would tend to be in the same direction as the moves in stock prices. Because when bond yields were, as an example, rising in that era, it was typically because growth was improving without the attendant concern about inflation. That's a great backdrop for equities, visa versa.
