Explore the Role of Investment Styles in building a diversified portfolio. Learn how growth, value, and blend strategies impact your returns and risk balance.
For many years, mutual fund investors have adhered to the principle of diversification. The prevailing belief is to construct a portfolio that includes a variety of funds across multiple categories and asset management companies (AMCs). However, could this strategy create a false sense of diversification, exposing your investments to concentration risk?
The truth is that you might possess funds from various categories and AMCs, yet if they all employ the same investment approach, your portfolio may not be genuinely diversified. An essential, often overlooked aspect of diversification is the investment style.

The Challenge
Constructing a portfolio can be likened to forming a cricket team. Just as a cricket match requires a thoughtful blend of batsmen, bowlers, and all-rounders to achieve victory, creating a successful mutual fund portfolio necessitates a variety of funds that employ different investment strategies.
Many investors mistakenly think they have achieved sufficient diversification by allocating their investments across various categories and asset management companies, without considering the investment approach. However, they may not recognize that this could result in their funds predominantly adhering to a single investment style. Relying on one style can lead to considerable underperformance in the portfolio when that particular style is out of favor.
Why is Style Diversification Important?
For the typical investor, it can be challenging to look beyond a fund’s name or category to grasp the true investment approach of the manager. This gap in information poses a significant obstacle. It hinders investors from making educated choices and crafting a robust portfolio that can thrive in various market conditions.
Recognizing and integrating various investment styles during mutual fund selection is essential. Approaches such as Value (acquiring undervalued stocks), Momentum (capitalizing on recent trends), and Quality (focusing on fundamentally strong companies) respond differently to changes in the market. A well-considered blend of styles can help minimize losses and stabilize returns over time.

A recent study examined funds across different categories and evaluated their performance and portfolios from the last five years, uncovering intriguing findings. It revealed that portfolios heavily tilted towards value and momentum strategies have outperformed over the preceding five years. For example, in the ELSS category, many funds exhibited a strong preference for either Value or Momentum investment styles. Conversely, most funds that leaned significantly towards the Quality investment style underperformed.
Advisors, distributors, and AMCs are essential in assisting investors to identify and evaluate the underlying style exposures within their portfolios. By incorporating a mix of different investment styles, investors can mitigate unnecessary risks and develop more robust portfolios.
The mutual fund industry is currently evolving towards increased clarity in style attribution and risk assessment. For investors, this change represents a significant chance to reconsider diversification—not merely across categories and AMCs, but also across different investment styles.
Understanding the importance of investment styles is a key aspect that many investors often neglect when assessing the diversification of their portfolios. You may possess a range of stocks or funds, but if they all adhere to the same investment style, your diversification may not be as effective.

- Investment styles like growth, value, and blend affect the performance of your assets throughout various market conditions. Growth investing emphasizes companies with high potential for expansion, whereas value investing aims at stocks that seem undervalued. A blend approach strives to harness the advantages of both styles.
- Gaining insight into investment styles is essential for mitigating risk and enhancing long-term returns. For example, during periods when growth stocks lag, value stocks might remain stable or even excel, providing your portfolio with resilience.
- Genuine diversification involves more than just distributing your funds across different sectors or geographical areas. It also encompasses varying the strategies used for choosing and managing your investments, where the significance of investment styles becomes paramount.
- Before making adjustments to your portfolio, evaluate closely: Are you inadvertently favoring a particular style? If so, it may be time to reconsider and adjust your allocations.
