[Source:] The S&P 500 is an index that weights 500 companies in order of their market capitalizations – if the market values company A more than company B, then company A is weighted more heavily in the index. But this isn’t a good investment strategy. Maybe company B earns more money, or maybe the weighting differential in the S&P 500 doesn’t reflect the earnings differential.
The same can be said about revenues or dividends. ...
... In short, the S&P 500 and many other indexes reflect what the market is doing, but they don’t make for good investments. Therefore ... leave funds like SPY to the traders.
Instead, I want to look at funds that weight their holdings based on other metrics, such as earnings, sales, or dividends. Fortunately there are several funds that are geared toward this kind of thinking. In fact, there are two companies that offer such ETFs ...
The first is RevenueShares. A RevenueShares fund is going to weight its holdings by revenues, not by market capitalization. ...
The second is WisdomTree ... This company offers many different kinds of funds, but two strategies in particular include dividend-weighted funds and earnings-weighted funds.
The expense ratios for RevenueShares and WisdomTree ETFs are higher. So is the bolded true and sound advice? Do other methods of weighting holdings consistently outperform?
