"Value has performed relatively poorly since the 2017 shift, but we believe challenges to the S&P 500’s dominance are mounting and resulting active opportunities away from the index are growing. At some point, this fault line will break, likely on the back of rising rates, and all investors will be reminded that the best time to diversify away from the winners is when it is most painful. The bargain of capturing long-term value may be short-term pain, but enough is eventually enough and it comes time to harvest the benefits.," said Clearbridge Investments in its market commentary.
