Equal Weight Index Funds
3 mins read

Equal Weight Index Funds are an innovative investment vehicle gaining popularity among investors. They offer a unique approach to diversification and portfolio construction that differs from traditional market capitalization-weighted indices. Understanding how these funds work and their potential benefits is crucial for investors seeking diversified exposure to the market.

What are equal weight index funds?

Equal weight index funds distribute investments evenly across all securities in a specific index, rather than weighting them by market capitalisation like traditional funds do. Unlike market cap-weighted funds that favour larger companies, each index company receives an equal allocation of funds in an equal-weight index fund. This approach creates a more diversified and balanced portfolio, as smaller companies have an equal influence on the index as larger ones. These funds mitigate concentration risk while providing exposure to a broad range of companies across various sectors and industries.

Available through mutual funds and ETFs, equal-weight index funds are typically more cost-effective than actively managed funds, offering investors an affordable means to diversify their investment portfolios.

Understanding equal weight index funds

  • Equal weight index funds track an index where each security receives the same weighting, regardless of its size or market capitalisation.
  • Unlike market capitalisation-weighted index funds, which favour larger companies, equal-weight index funds offer diversified exposure to stocks across various industries and sectors.
  • This indexing method helps mitigate the risk of concentration in any single company or industry, providing investors with a balanced portfolio.
  • Equal-weight index funds ensure that smaller companies have an equal impact on the portfolio as larger ones, offering a more balanced exposure to the overall market.
  • These funds typically have lower fees and expenses compared to actively managed funds, potentially leading to better returns over time.
  • However, it is important to note that investing in equal-weight index funds does not guarantee higher returns, and suitability depends on an investor's objectives and risk tolerance.
  • Before investing, investors should carefully assess their investment goals and understand the underlying index methodology.

Momentum vs value

Momentum and value are two distinct investment strategies used when selecting stocks. Value investing involves identifying stocks that are undervalued based on their intrinsic worth. Investors employing this strategy believe that the market sometimes undervalues certain companies, providing an opportunity to purchase them at a discount. Conversely, momentum investing focuses on stocks that have shown significant price increases over a specific period. Momentum investors anticipate that stocks that have recently performed well will continue to do so.

Both approaches have their advantages and disadvantages and may perform differently depending on market conditions. Value investing emphasises buying low and selling high, while momentum investing capitalises on the theory of "the trend is your friend." Investors must carefully consider their investment goals, risk tolerance, and the fundamental characteristics of the companies they invest in when choosing between these strategies. Understanding the market environment and conducting thorough analysis is essential for successful investing, whether one chooses a momentum or value approach.

Market-cap-weighted vs equal-weight indices

  Equal-weight Indices Market-cap-weighted Indices
Weighting method Assigns equal weight to all companies Gives more weight to companies with higher market capitalisations
Impact on index performance Each company has an equal impact on performance Larger companies have a greater impact on performance
Investor preference Appeals to investors seeking exposure to smaller businesses or a more diverse portfolio Preferred by investors seeking exposure to bigger, more established companies
Diversification Offers a more diversified portfolio May lack diversification due to focus on larger companies

Equal-weight indices and market-cap-weighted indices represent two distinct methodologies for constructing stock indices. While equal-weight indices distribute the weight evenly among all companies, market-cap-weighted indices give more weight to companies with higher market capitalizations. Investors' preferences often dictate the choice between the two indices, with equal-weight indices appealing to those seeking exposure to smaller businesses or a diversified portfolio, while market-cap-weighted indices are favoured by investors looking for exposure to larger, more established companies.

Advantages and disadvantages of equal weight index funds


  • Diversification: Equal-weight index funds embrace true diversification by evenly spreading risk across all constituents rather than concentrating it in a few large-cap stocks. This helps avoid vulnerability during sectorial rotations and corrections.
  • Value investing: These funds follow a value investing approach, considered a superior market strategy compared to momentum-driven investing.
  • Trend independence: No single stock can dictate the trend of the index, providing a more balanced representation of the market.


  • Increased transaction costs: Higher transaction costs contribute to a higher expense ratio compared to other funds.
  • Volatility impact: Volatility affects equal-weight index funds significantly. While blue-chip stocks provide stability in volatile markets, equal-weighting them with others may result in a loss of that stability.
  • Anomalies in corporate actions: Anomalies may occur during stock splits and mergers, impacting the effectiveness of equal-weight index funds.

Should you invest in equal weight index funds?

Investing in Equal Weight Index Funds can be suitable for investors seeking diversified exposure to the market and looking to reduce concentration risk in their portfolios. However, investors should carefully consider their investment objectives, risk tolerance, and time horizon before making investment decisions.


Equal weight index funds offer investors a unique opportunity to gain diversified exposure to the market while minimising concentration risk and capturing different market trends. By understanding how these funds work and their potential benefits, investors can make informed decisions to achieve their investment objectives. It is advised that with any investment, investors should conduct thorough research and consult with financial professionals to determine whether Equal Weight Index Funds align with their investment goals and risk tolerance.
