Jack Bogle’s Top 10 Common Sense Investing Principles

Imagine the investment styles of two investors. 

The first investor spends dozens of hours on the stock market, buying and selling frantically hoping to strike it rich every day. 

The second investor simply puts his money into a broad market index fund and holds it for decades, hardly thinking about the daily price gyrations of the market. 

After a few years, normally the second investor is better off than the first investor with better returns, less anxiety and more minimal financial regrets. This uncomplicated method of investing is consistent with the investment philosophy of Jack Bogle, among the most important investors in modern finance.

Jack Bogle is the founder of The Vanguard Group, and in 1976, he changed investing forever with the introduction of the first index mutual fund. 

When individual active investing and stock picking were in vogue, Bogle introduced a radically different point of view by encouraging individuals to keep things simple, think long term and minimize investment costs. 

His common-sense investing philosophy has helped millions of people compound wealth slowly over time without speculative market forecasting and the aid of high-fee professional money managers.

Jack Bogle’s Common Sense Investing Principles for Indian Investors

Jack Bogle believed investing is not complicated. His principles are more about the things that really matter, long-term discipline, low-cost investing, and avoiding complexity. 

Here are 10 timeless tips for Indian investors looking to grow wealth intelligently.

1. Think in Decades, Not Days

Jack Bogle would say that investing is a long game, not a short game. It’s how long you can stay in and hold your investments. It’s about how much time you are in the market, not timing the market. The longer the timeframe, the bigger the available growth as compounding takes place. In other words, short term price changes look to be less powerful and significant.

For instance, you want to take $10,000 and invest in an S&P 500 index fund with an average annual return of 8%. After 30 years your compound investment will be valued at more than $100,000. 

However, if you are in and out of the markets to try and avoid losses you are probably missing more than half those returns.

2. Lower Expenses, Keep Your Returns

Every rupee that is paid in fees is a rupee that is not compounding for you. High expense ratios and high commissions incrementally deduct from your long-term returns. Bogle suggested that you take advantage of the lowest cost investment alternatives so you can keep as much of your returns as you can.

For example, let’s assume two investors both invested the same initial amount of money, in the same performance of the markets, but to have the same initial amount of money an investor had to pay higher fees each year, and the other investor is using a low fee plan. 

The investor in the low fee plan is going to have significantly more capital after 20 years, simply because more of the investor’s money was invested instead of taken away every year.

3. Diversification is key to risk management

Diversifying gives an investor the option to spread their investment dollars across multiple companies and multiple industries thereby limiting the risk that a poor investment in one or potentially more stocks or industry sectors can have on the overall portfolio.

Imagine an investor who diversifies across industries including health care, energy, consumer products, and infrastructure, etc. This investor can protect themselves better as there can be one or multiple industries that perform poorly than an investor who simply buys stocks in one industry (technology, or banking for example). 

A diversified portfolio can create a degree of stability and so increase the odds of receiving positive returns.

4. Be Average to Win

It is difficult to try to outperform the market by stock picking or frequent trading. Even professional fund managers struggle to beat the market over long time periods. And Bogle’s was simply, stay average, and you will probably outperform most of the investing public over time.

Many investors spend years trying to pick the best stocks or sectors and eventually learn that they would have forever done better by investing in the entire market and letting it sit. 

That one decision not only reduced costs, but it also avoided emotional mistakes.

5. Stay the Course

The key to your investment strategy, whether you are in a bull market or bear market, is to stick to the plan you put together. Markets can be cyclical, with peaks and valleys. Mr. Bogle cautioned against investors allowing panic to set in or trying to time the cycles, telling investors to fearlessly stay the course they originally laid out.

When the market is dropping, many investors panicking, and thinking about pulling their money out. 

However, investors who are continually contributing and who can resist the panic sell temptation, tend to be rewarded with a recovery and, in the long run, better overall investment performance than selling out at the worst point in time and missing the recovery.

6. Allow Index Investing to Do the Heavy Lifting

Index investing is a passive method that lets the overall market tell the investor how well they are doing. 

Index investing began with Bogle, who devoted his life to developing the idea. He also publicized index investing as a simple way to accumulate wealth, low costs, and low effort.

An investor that routinely invests in a portfolio that mimics an entire market index, never has to study individual companies or consume news updates.

7. Stay Away From The Noise

Much of the financial news and website predictions are sensational and typically short-term. Responding to media agendas based on hype or fear rarely leads to a good outcome. Investors should tune out the noise and stick with their plan for the long-term.

It is not unusual to read about predictably dire media proclamations about enormous losses or wild swings in the market during election cycles, economic slowdowns, or global crises. The usually rational and well-informed long-term investor benefits greatly from market media commentary about wild speculation. 

Those irrational autodidacts respond emotionally to media speculation and typically harebrained negative calls than do disciplined and rational investors, who make it a habit to look past the noise, and stay focused, calm, and rational with their long-term objectives intact.

8. Discipline Versus Emotion

Discipline is one of the most powerful characteristics of successful investors. This can mean investing regularly, following your strategy, and deliberately checking to avoid emotional decisions that are based on market changes and peer pressure.

Someone who invests a fixed amount of money every month regardless of whether the market is going up or down benefits from cost averaging. Over time, this smooths out the cost of investing and minimizes the risk of investing at the wrong time. In the end, consistency is more valuable than emotion.

9. Balance With Intention

Each portfolio must fit the personal goals, age, and risk tolerance of the investor. Bogle suggested some easy rules to maintain an appropriate balance between equities that offer growth, and debt that provides stability. Investors should adjust their balance as their financial situation changes.

For example, an early-career professional may invest more in equities than an investor who is nearing retirement and can consequently afford to move towards fixed income investments that preserve savings. In this way, your portfolio can support your life goals through each stage of your life.

10. Recognize Speculation For What It Is

Speculation entails high risk, based on guesses or trends. Investing involves careful planning and disciplined execution, while speculation is based on luck and timing. Bogle was careful to point out how speculation loses money, rather than builds wealth.

Many people buy up quickly rising assets expecting it to make them income, only to watch them crash and sustain huge losses. Conversely, those who avoid speculation and follow their long-term varied investment strategy will create wealth gradually and consistently.
