Sliced Breadth

  • May 18, 2023

The S&P 500 posted a 7.7% price gain for the six months ended April 30th, although this advance has been a hard-fought battle as gains have resulted from a narrow list of drivers. Style leadership has been concentrated in mega-cap tech names, such that the ten members of the NYSE FANG+® Index have produced 77% of the S&P 500’s YTD gain. Furthermore, gains over recent months have resulted solely from expanding multiples. Narrowness in either thematic leadership or price drivers is concerning because breadth is a useful concept in evaluating the staying power of a market advance. In light of this year’s market action, we are intrigued by the notion of measuring breadth not simply by price moves alone but by examining each of these two important sub-components individually. Does today’s environment, where price gains are driven by valuation increases alone, tell us anything about future market returns?
