How Many Stocks Should You Own in Your Portfolio?

Balancing Risk, Return, and Discipline in Equity Investing

You invest in stocks to achieve your financial goals — not to chase returns for their own sake.
As the saying goes, “Don’t let the tail wag the dog.” Your goal is the dog; returns are merely the tail that follows.

Many investors forget this distinction. They chase the latest “high-potential” idea without weighing an equally important question:
 “How much can I lose if I’m wrong?”

The truth is that investing is always about the future, and the future is uncertain. That means risk can never be eliminated — only managed. And two tools help you do that effectively: discipline and diversification.

The Role of Discipline and Diversification

1. Discipline Keeps Emotions in Check

Discipline ensures that you don’t let short-term excitement or fear drive long-term decisions.

• In bull markets, investors often grow overconfident, loading up on new ideas when early bets succeed.
• In bear markets, they swing the other way — losing confidence, selling quality stocks, or overdiversifying into dozens of holdings.

Discipline keeps you focused on process, not outcomes. A sound process may not work every quarter, but it wins across market cycles.

2. Diversification — The Only Free Lunch in Investing

Diversification smooths out your investment journey by spreading risk across companies, sectors, and cycles.

Statistical studies have shown that owning 16–32 stocks provides most of the diversification benefits that the market can offer.

After about 32 stocks, additional diversification provides minimal incremental risk reduction.

That’s why even benchmark indices like the Dow Jones or Sensex hold roughly 30 stocks — enough to capture the market’s essence without unnecessary overlap.

How Many Stocks Should You Own?

An ideal investor portfolio, in MoneyWorks4Me’s view, should have 20–25 stocks.

This range strikes the perfect balance — diversified enough to manage risks, yet focused enough to capture meaningful upside from quality ideas.

• Below 15 stocks → too concentrated; a few mistakes can drag returns.
• Above 30–35 stocks → overdiversified; winners don’t move the needle, and monitoring becomes difficult.

Should All Stocks Be Weighted Equally?

Not all businesses are created equal. Some are consistent compounders with strong moats and earnings visibility, while others are cyclical or smaller in scale.

Hence, your allocation should reflect quality and conviction — not be spread evenly.

MoneyWorks4Me’s Stock Allocation Framework

• Minimum 16 stocks → no stock > 6–7% of total portfolio.
• Maximum 32 stocks → no stock < 3% of portfolio.

This ensures that stable businesses dominate the portfolio while cyclical or risky names have limited downside impact.

The result: your portfolio’s volatility remains lower or equal to the market, yet retains upside exposure through well-chosen businesses.

Why Not Own a Concentrated Portfolio of 5–8 “Best Ideas”?

Because no one knows which 5–8 ideas will truly become wealth creators.

Real-World Example: The Capital Group Experiment

Capital Group, a large Los Angeles-based fund house, launched a “Best Ideas” fund — composed of their portfolio managers’ top picks.

The result? It underperformed its benchmark repeatedly.

Why? Because high conviction often reflects time spent, not necessarily accuracy. Overconfidence in one’s research doesn’t control the future.

The Power of Diversification: Data Speaks

Global Study (Hendrik Bessembinder, 2018)

• Over 90 years, 96% of all U.S. stocks underperformed short-term Treasury bills.
• Just 4% of stocks created all $34.8 trillion in shareholder wealth.
• Only 50 stocks accounted for nearly 40% of total wealth creation.

Indian Study (Motilal Oswal, 2020)

• From 1995–2020, Sensex grew at 9.2% CAGR.
• Only 100 companies out of the broader universe outperformed that 9.2% mark.
  In other words, roughly 20% of listed stocks drove the market’s long-term returns.

Owning just a few stocks drastically lowers your odds of catching these big winners.

Diversification, on the other hand, improves your chances of owning at least a few future wealth creators.

The Balanced Approach: Neither Overdiversified Nor Concentrated

At MoneyWorks4Me, we believe in intelligent diversification — owning enough high-quality businesses to reduce risk without diluting returns.

We don’t advocate holding hundreds of mediocre names, nor do we chase extreme concentration in a handful of bets.

Investing is about managing risk, not eliminating it.
You will always face uncertainty — but how you prepare for it determines whether you achieve your goals.

If you already own a stock portfolio, you can use our Portfolio Manager to identify risks and rebalancing actions in real-time — free of cost.
