Equal Weight


Equal weight is a type of portfolio diversification strategy where all securities are assigned the same weight or percentage allocation. This means each stock in an index or a fund carries the same significance, regardless of its size or market value. It’s intended to reduce risk by giving smaller companies an equal footing with larger, more established companies.


The phonetic transcription of “Equal Weight” is /ˈiːkwəl weɪt/.

The term “Equal Weight” is significant in business and finance as it refers to a type of investment strategy wherein all stocks in a portfolio or an index fund are given the same weightage. This method is in contrast to market capitalization weighting, where the weightage is determined by the size of an associated company. The importance of equal weight lies in its potential to balance risk and avoid the overemphasis on larger companies. This strategy allows smaller companies to contribute meaningfully to the portfolio’s performance. Furthermore, it encourages diversification and frequent rebalancing of the portfolio, providing potential benefits of buying low and selling high.


Equal Weight is primarily used within the context of an investment portfolio or index fund where all the securities hold the same weightage. The purpose of using Equal Weight is to ensure that smaller companies have just as an important role in the performance of the portfolio as larger ones, otherwise, this would not necessarily be the case in market-capitalization-weighted funds. This broadens the portfolio’s exposure and potentially allows for greater diversification, effectively reducing the degree of risk associated with the investment. Additionally, constantly maintaining an equal weight strategy necessitates regular rebalancing, an exercise which could generate consistent returns if securities are sold high and bought low during the rebalancing process.Another purpose of the Equal Weight approach is to avoid the over-concentration of larger companies dominating the portfolio’s performance. For example, if one or two larger companies experience significant growth or decline, an equally weighted fund won’t be overly affected because no single security carries more weight than another. This methodology ensures that every company, regardless of size, has an equal opportunity to contribute to the results of the overall portfolio. Thus, an equally-weighted portfolio could potentially provide investors with enhanced returns and beneficial risk-adjusted performances.


Equal Weight is a type of equity allocation strategy where all components of a portfolio, index, or fund are assigned the same weight. Even though there are many examples of equal weighting in the world of finance, many market indices are not equally weighted. However, here are three situations where equal weight is applied:1. S&P 500 Equal Weight Index (EWI): This is an equal weight version of the S&P 500 Index. All components of the S&P 500 EWI are given the same importance in terms of their effect on the value of the overall index. This index is rebalanced quarterly in order to maintain the equal weights. This strategy allows for a more evenly distributed performance across each sector, which implies that the index is not just driven by a small number of high value stocks.2. Invesco S&P 500 Equal Weight ETF (RSP): This is a fund that seeks to track the investment results of the S&P 500 Equal Weight Index. Each of the 500 stocks in this fund is given equal weight, as opposed to the traditional S&P 500 index where stocks are weighted by their market capitalization value. 3. WisdomTree’s ETFs: WisdomTree is an ETF (Exchange-traded fund) provider that offers several equal-weight ETFs. For instance, the WisdomTree MidCap Dividend Fund tracks an index of medium-size companies weighted by dividends. All dividends are treated equally, rather than being weighted by size as in most other indices.

Frequently Asked Questions(FAQ)

What is Equal Weight in finance and business?

Equal Weight is a type of weighting that gives the same weight or importance to each stock in a portfolio or index fund. The strategy is the opposite of capitalization-weighting where individual securities are given different weights based on their market capitalization.

Why would an investor choose an Equal Weight strategy?

Equal Weight strategy offers diversification as it doesn’t allow certain stocks to dominate the portfolio or index fund due to their larger size in the market. This way, the performance of smaller companies has an equal impact as larger ones.

What are the potential advantages of Equal Weight investment strategy?

Equal Weight investment strategy has the potential to outperform market-cap weighted indexes. This is mainly because it is more likely to take advantage of the ‘size effect’ and ‘value effect’. Plus, it avoids concentration risk where a limited number of stocks dominate the portfolio.

What are the potential disadvantages of Equal Weight investment strategy?

The primary disadvantage is that it requires frequent rebalancing, which can be costly due to transaction costs. Also, equal weight strategy may underperform the market-cap weighted portfolios during the times when the larger stocks drive the market returns.

How is rebalancing done in an Equal Weight portfolio?

Rebalancing involves adjusting the weights of each stock or asset in a portfolio to maintain an equal weightage. This is usually done periodically, such as quarterly or annually, or whenever a significant drift occurs due to the performance differences.

Can Equal Weight strategy be applied to any type of asset or just stocks?

While it’s most commonly used with stocks, Equal Weight strategy can be applied to any asset class such as bonds, commodities, or real estate.

What is the difference between Equal Weight and Market-Cap Weighted indexes?

In an Equal Weight index, each component is assigned the same weight. In contrast, a Market-Cap Weighted index assigns a weight to each component according to its market capitalization, meaning larger companies carry a larger weight in the index.
