In the sensible beta panorama, equal-weight ETFs are among the many most battle-tested ideas. Take into account the Invesco S&P 500 Equal Weight ETF (RSP).
The $28.78 billion RSP lately turned 18 years outdated, making it not solely the godfather of equal-weight ETFs, however one of many oldest sensible beta ETFs of all stripes. Weighting shares equally beneath one umbrella would not all the time result in outperformance, however RSP’s long-term observe document is spectacular, and with worth and smaller shares performing nicely this 12 months, so is the Invesco fund. As of July 5, RSP is greater by 20.2% year-to-date, a bonus of 340 foundation factors over the cap-weighted S&P 500.
Analysis means that when equal-weight portfolios are rebalanced comparatively steadily (RSP rebalances quarterly), they will prime price- and value-weighted options. Grigory Vilkov and Yuliya Plyakha of Goethe College and Raman Uppal, professor on the EDHEC Enterprise College, beforehand constructed equal-, value-, and price-weighted portfolios of 100 randomly chosen S&P 500 parts from the previous 40 years, discovering that the equal-weight choices persistently beat price- and value-weighted rivals.
“The entire return of the equal-weighted portfolio was greater than that of the worth and price-weighted portfolios by 271 and 112 foundation factors a 12 months,” in line with the researchers.
A Good Time for RSP?
As famous above, RSP’s long-term observe is spectacular, proving there’s sturdiness with equal-weight methods. Nonetheless, owing to equal-weight typically leaning into the scale and worth elements, the fund is a very sturdy concept at instances when one or each of these elements are excelling.
Relating to measurement advantages, it is necessary for traders which are new to equal weighting to appreciate that just because RSP weights shares in equal proportions, it is not a small cap fund. The typical market capitalization of its parts is slightly below $72 billion, in line with issuer knowledge. That is nicely into giant cap territory. Giant cap equal-weight methods are more likely to be much less risky than small cap equivalents and barely extra risky than cap-weighted giant cap fare.
“The volatility of the return on the equal-weighted portfolio was 17.90% a 12 months, which was greater than the 15.83% and 16.46% for the worth and price-weighted portfolios,” notice Vilkov, Plyakha, and Uppal.
General, the researchers say their findings verify the notion that equal-weight’s benefits are largely sourced from measurement and worth publicity. That stated, RSP is not overly depending on worth shares, as such names characterize about 37% of the portfolios. As for smaller inventory publicity, small caps characterize lower than 1% of the roster. There’s an roughly 55% tilt towards mid caps.
