10 Thumb Rule for Investment in the Stock Market | 5paisa (2024)

Investing is like a game with a few simple rules for success, but it's also a minefield of emotional traps and pitfalls. Despite knowing the age-old advice of "buy low, sell high," our emotions often lead us astray, causing us to panic when the market dips and jump in when it's at its peak.

That's why having a set of "golden rules" is essential to navigate the unpredictable world of investing. Sure, anyone can ride the wave when the market is soaring, but it's during turbulent times that separates the winners from the losers.

So, here are 10 golden rules of investing to help you become not just successful, but hopefully, wealthier too.

Understanding How Fast Your Money Grows

Rule of 72: Doubling Your Money

Ever wondered how long it would take for your money to double? This is where the Rule of 72 comes in handy. It's a simple formula that allows you to estimate the time it takes for an investment to double in value. Divide 72 by the annual rate of return on your investment, and you'll get the approximate number of years it will take to double your money. For example, if you're getting a 6% return, your money will double in approximately 12 years.

The Rule of 72 is a powerful tool because it gives investors a quick way to assess the potential growth of their investments. By understanding this rule, investors can make more informed decisions about where to allocate their capital and how long to hold their investments.

Rule of 114: Tripling Your Money

Now, let's take it a step further. The Rule of 114 tells you how long it will take for your money to triple. Similar to the Rule of 72, divide 114 by the rate of return to find the number of years. With a 6% return, your money will triple in approximately 19 years.

Tripling your money may seem like a distant dream, but understanding this rule can help investors set realistic goals and make strategic investment decisions.

Rule of 144: Quadrupling Your Money

For those who dare to dream even bigger, there's the Rule of 144. This rule tells you how long it takes for your money to quadruple. Divide 144 by the rate of return, and you'll know the number of years it will take. At a 6% return, your money will quadruple in about 24 years.

Understanding these rules empowers investors to plan for the future, set achievable targets, and make smarter investment choices.

Understanding How Fast Your Money Loses Value

Rule of 70: The Impact of Inflation

While it's essential to understand how fast your money can grow, it's equally important to understand how fast its value can diminish. The Rule of 70 helps you grasp the impact of inflation on your wealth. Divide 70 by the inflation rate to estimate how long it takes for your wealth to halve in value. For example, with a 5% inflation rate, your wealth will halve in around 14 years.

Inflation erodes the purchasing power of your money over time, so it's crucial to account for it when making investment decisions.

Thumb Rules for Investing

The 10,5,3 Rule: Expected Returns

Investors often wonder what kind of returns they can expect from their investments. The 10,5,3 rule offers a simple guideline. Expect around 10% returns from long-term equity investments, 5% from debt instruments, and 3% from savings bank accounts.

This rule helps investors set realistic expectations and allocate their investments accordingly.

Emergency Fund Rule: Prepare for the Unexpected

Building an emergency fund is essential for financial security. Aim to set aside six months to one year's worth of expenses. Invest this fund in liquid assets like liquid mutual funds to earn slightly higher returns while maintaining liquidity.

An emergency fund provides a safety net, allowing investors to weather unexpected expenses without derailing their long-term financial goals.

100 Minus Age Rule: Asset Allocation

Asset allocation is key to managing risk in your investment portfolio. Use the 100 minus age rule to determine the percentage of your portfolio allocated to equities. The rest should be invested in debt. For example, if you're 25 years old, consider allocating 75% to equities and 25% to debt.

This rule helps investors strike the right balance between risk and return based on their age and risk tolerance.

10% for Retirement Rule: Securing Your Future

Planning for retirement may seem distant, but it's crucial to start early. Aim to save at least 10% of your current salary for retirement, increasing it by another 10% each year. This disciplined approach can help you build a substantial retirement corpus over time.

By starting early and saving consistently, investors can enjoy a comfortable retirement without relying solely on social security or pension benefits.

The 4% Withdrawal Rule: Sustainable Income

During retirement, it's essential to ensure a steady income stream while preserving your savings. The 4% withdrawal rule suggests withdrawing no more than 4% of your retirement corpus annually. Adjust this amount for inflation to maintain purchasing power.

This rule helps retirees strike a balance between enjoying their retirement years and ensuring their savings last a lifetime.

The Net Worth Rule: Assessing Wealth

Ever wondered if you're truly wealthy? The net worth rule provides a simple calculation. Multiply your age by your gross income and divide by 10 (or 20 in India). If your net worth exceeds the result, congratulations – you're wealthy!

This rule offers a quick way to assess your financial standing and track your progress towards your wealth-building goals.

These thumb rules serve as invaluable guides for investors, providing clarity and structure in an often complex financial landscape. By understanding and applying these rules, investors can make informed decisions, set realistic goals, and achieve financial success over the long term.
