The 70-20-10 Rule In Investing- A Strategic Framework For Your Portfolio

Market movements are an inherent feature of investing. While short-term fluctuations cannot be avoided, structured allocation approaches may help investors navigate different phases of the market cycle. One such framework is the 70-20-10 rule, which proposes spreading investments across different risk segments to balance relative stability and long-term growth potential. This form of diversification may help moderate the impact of short-term volatility on an overall portfolio.

What is the 70-20-10 Rule? Fundamentals of resource allocation

The 70-20-10 rule is a broad asset allocation framework sometimes used for illustrative purposes in investing. It involves dividing an investment corpus into three segments based on risk exposure—approximately 70% towards relatively stable components, 20% towards assets with higher risk and growth potential over time, and 10% towards more aggressive exposures.

The intent behind this structure is to create a portfolio-based approach that may help manage volatility, while still allowing room for potential long-term wealth creation. The framework does not eliminate risk and must be adapted based on individual goals, time horizon, and risk appetite.

The core concept- 70%, 20%, and 10% allocation

• 70% (Core allocation): This portion is designed to form the foundation of the portfolio. It generally focuses on diversification, liquidity, and relative stability. Depending on an investor’s horizon and risk appetite, this segment may include high-quality debt mutual funds, money market instruments, or large cap equity funds. It is important to note that equity mutual funds, including large cap funds, invest more than 65% in equities and are therefore classified as very high risk. Their inclusion in the core is typically linked to long investment horizons and the potential to manage interim volatility.
• 20% (Measured growth allocation): The 20% segment seeks to add incremental growth potential without materially increasing overall portfolio concentration. This may include diversified equity funds such as flexi cap or mid cap funds, which may offer higher long-term growth potential but also involve higher volatility than the core allocation. The objective here is exposure to additional growth drivers while maintaining balance and diversification.
• 10% (Higher-risk allocation): The remaining 10% is allocated to higher-risk segments that may experience sharper volatility and deeper drawdowns. This may include sectoral, thematic, or smaller company-oriented strategies. Limiting this exposure is intended to help ensure that unfavourable outcomes do not disproportionately affect the overall portfolio.

Applying the 70-20-10 rule to your investment portfolio

Applying this framework may be easier when investors focus on portfolio roles before selecting specific products. The process typically begins by identifying requirements such as long-term growth potential, liquidity, and diversification. The allocation is then layered with measured growth exposure, while keeping higher-risk segments capped.

Benefits of adopting the 70-20-10 mindset for your investments

A structured allocation approach may support disciplined investing during volatile phases. • Lower concentration risk by spreading exposure across segments • A balance between potential long-term growth and relative stability • Improved behavioural discipline by reducing emotionally driven decisions

Implementing the 70-20-10 rule

Investors considering this framework may follow a structured process:

• Assess individual risk appetite and investment horizon
• Assign suitable mutual fund categories to each allocation segment
• Begin investments through systematic or lump sum routes, as appropriate
• Review allocations periodically and rebalance when deviations arise
• Stay informed and align changes with evolving goals

FAQs

Is the 70-20-10 rule a fixed investment strategy, or can it be customised?

No. It is a guiding framework and may be adjusted based on changing goals, time horizon, and comfort with volatility.

How does my personal risk tolerance affect my individual 70-20-10 investment split?

Risk tolerance influences how much interim volatility an investor may be able to remain invested through. Lower tolerance may lead to a higher allocation towards relatively stabilising components.

Should I periodically rebalance my portfolio to maintain the 70-20-10 allocation?

Periodic rebalancing may help maintain the intended risk profile as markets fluctuate. This may be done using future investments or portfolio adjustments, subject to costs and tax considerations.

What risks are associated with the 10% higher-risk allocation?

Higher volatility, sharper drawdowns, and liquidity sensitivity are key risks. Keeping the allocation limited may help contain overall portfolio impact.

May this framework be applied to long-term goals such as retirement?

Yes. The framework may guide long-term investing, with allocations typically evolving over time as stability requirements increase closer to the goal.
