How to Grow Money With Stocks: The Basic Long-Term Approach

How Stocks Make Money

There are two main sources of stock investment returns.

1. Capital gains

If a stock bought for 1 million yen rises to 1.2 million yen, the gain is 200,000 yen.

ROI = Profit / Investment amount x 100

In this example, ROI is 20%.

2. Dividends

Companies may return part of their profits to shareholders.

Example:

• Investment amount: 1 million yen
• Dividend yield: 3%

Annual dividends would be about 30,000 yen before taxes.

The Classic Pattern

Long-term investing

Instead of short-term trading, hold for 10 or 20 years.

Stock prices move sharply in the short term, but over the long term, investors may benefit from corporate growth and economic growth.

Diversification

Do not put everything into one company.

Diversify across:

• multiple companies
• ETFs
• mutual funds
• regions and sectors

Use compound growth

Reinvest dividends and gains where appropriate.

A = P(1 + r)^n

The longer the period, the more powerful compounding becomes.

Beginner Steps

Step 1: Consider using NISA

In Japan, NISA can improve tax efficiency because eligible investment gains are tax-exempt.

Step 2: Consider diversified index funds

Examples include funds linked to:

• global equities
• U.S. stock indexes

One fund can provide exposure to hundreds or thousands of companies.

Step 3: Keep investing regularly

For many beginners, continuing a monthly investment plan is more important than predicting the market.

Common Mistakes

Chasing quick riches

Putting all money into a stock trending on social media can lead to large losses.

Selling during a crash

Panic selling during market declines can prevent investors from benefiting from later recoveries.

Not investing at all

If inflation continues, cash alone may lose purchasing power in real terms.

Example: Investing 1 Million Yen

If the annual return were 5%, the rough image would be:
