Invesco S&P 500 Equal Weight ETF gives overweightings to smaller stocks in the S&P 500, but that probably won’t give it a durable edge over the market after adjusting for risk. It warrants a downgrade to a Morningstar Analyst Rating of Neutral from Bronze. Previously, the fund was rated based on its ability to beat the large-blend category average. However, as a strategic-beta fund, the category index, the Russell 1000, is the better benchmark.
The fund fully replicates the S&P 500 Equal Weight Index, which includes all stocks in the S&P 500 and weights them equally. By assigning an equal weight to the smallest stocks in the S&P 500 as the largest, the fund mechanically overweights the smaller stocks in the S&P 500 and underweights the larger names in the index. This pulls the average market capitalization of its holdings closer to that of the Russell MidCap Index than to the S&P 500. As a result, the fund carries higher risk than the market-cap-weighted S&P 500. The fund delivers similar performance to market-capitalization-weighted mid-cap funds.
Equal weighting helps this portfolio avoid increasing its exposure to areas of the market as they become more expensive, which is a criticism of market-cap-weighting. However, it fails to benefit from the market’s collective wisdom about the relative value of each security. Market prices tend to do a good job reflecting information that is available to the public, making it hard to beat the market without taking more risk, especially over the long term. By ignoring this information, the fund may increase its exposure to stocks with deteriorating fundamentals and trim positions in firms with improving outlooks when it rebalances to restore its equal weightings each quarter.
Equal weighting is arbitrary. While it may reduce concentration and give this fund less exposure to firm-specific risk than the S&P 500, it also increases turnover and transaction costs.
Invesco charges 0.20% annually for this fund. Although it is cheaper than actively managed funds in the large-blend Morningstar Category, there are cheaper alternatives.
