Is It Finally Time for Investors to Consider Equal-Weighted ETFs?

What are equal-weighted ETFs?

Most index ETFs allocate their weightings based on a concept known as "float-adjusted market cap."

To simplify, "market cap" is the total value of all a company's shares of stock, found by multiplying the price of a single share by the total number of shares available.

"Float-adjusted" narrows this down to only include shares publicly available for trading, leaving out those held by insiders, governments, or under other restrictions.

This weighting approach means that in indices like the S&P 500, larger companies, such as Microsoft and Apple, dominate because they have the largest market caps. The greater a company's market value, the bigger its impact on the index's performance.

The benefits of this method are notable. It results in low turnover; beyond the occasional additions and deletions, the portfolio largely manages itself. For proponents of efficient markets, letting the most valuable companies lead makes sense, as it reflects the market's natural selection.

An alternative method is equal weighting, which is exactly what it sounds like, giving each stock in an index the same weight. In the case of the S&P 500, every stock would be assigned a weight of 0.20%. This strategy significantly cuts down on concentration risk and balances out sector representation more evenly.

However, equal weighting introduces its own challenges. It leads to higher costs due to increased turnover; portfolios must be rebalanced regularly to keep the weights equal, which can dampen momentum. Moreover, this strategy increases exposure to mid and small-cap stocks. Though these stocks may have higher growth potential, they also bring greater volatility.

The best equal-weighted ETFs

When it comes to equal-weighted ETFs, Invesco's offerings stand out prominently. Their flagship, the Invesco S&P 500 Equal Weight ETF (RSP), has been a staple in the market since its inception in April 2003, marking over two decades of performance. It’s also the largest in its category, boasting over $50 billion in assets under management.

Notably, RSP differentiates itself with a 0.20% expense ratio and higher turnover due to its quarterly rebalancing schedule. Despite these factors, it has admirably kept pace with the SPDR S&P 500 ETF (SPY), and before the significant market movements in 2023, RSP was even outperforming SPY.

The depth of Invesco's equal-weight strategy extends beyond just a broad market approach. For investors interested in diving into specific sectors of the S&P 500 through an equal-weight lens, Invesco provides a suite of sector-specific ETFs.

One such example is the Invesco S&P 500 Equal Weight Technology ETF (RSPT), allowing investors to focus on the technology sector while adhering to an equal-weight investment philosophy.
