What are growth stocks? Explaining how to find, choose, and avoid failure for beginners

【summary】

Growth stocks are stocks of companies that have high growth rates in sales and profits and are expected to increase their corporate value in the future.

A characteristic of a company is that it places more emphasis on ``how much it will grow in the future'' than on current profits and dividends. Investment themes are likely to be found in companies in expanding markets such as AI, semiconductors, cloud, digital services, and medical technology.

However, it is not as simple as buying growth stocks because they are likely to grow. While you can expect a large increase in price, if the stock does not grow as expected, the stock price may fall significantly. Beginners will want to check not only sales growth, but also profit margin, operating cash flow, competitive advantage, high PER ratio, PEG, interest rate environment, and diversified investment.

This article is a general learning article that explains the meaning of growth stocks, the difference from cheap stocks, how to find them, benefits, risks, and points where beginners tend to make mistakes. It is not a recommendation to buy or sell individual stocks. Stock investments are subject to risks such as price fluctuations, loss of principal, liquidity, deterioration of business performance, rise in interest rates, and deterioration of market conditions.

What are growth stocks?

Growth stocks are stocks of companies whose sales and profits are growing faster than the market average, or are expected to grow in the future.

Investors invest based not only on current performance, but also on the following factors:

Future profit growth
Increase market share
New business success
Overall industry growth
Expansion of overseas expansion and new services

For example, companies that are seen as growth stocks are more likely to appear in fields such as AI, semiconductors, cloud, digital services, cybersecurity, medical technology, and labor-saving.

However, just because a theme is popular does not mean it is a growth stock. In some cases, only stock prices rise first, and actual sales and profits do not catch up.

Difference between growth stocks and cheap stocks

The first thing beginners want to understand is the difference between growth stocks and cheap stocks.

Item	Growth stocks	Cheap stocks
Points to focus on	Future growth	Current undervalue
Dividend	Less tendency	More tendency
Stock price evaluation	PER and PBR tend to be high	PER and PBR tend to be low
Price movement	Tends to increase	Relatively stable
Investment period	Tends to be long-term oriented	Often reviewed in the medium to long term
Main risks	Diminished expectations, rising interest rates, underachieving performance	Low growth, deteriorating performance, remaining undervalued

To put it quite simply, growth stocks are investments that bet on ``the future rather than the present.''

On the other hand, undervalued stocks are an investment to see if the current valuation is too low. One is not always better than the other. Suitability or unsuitability changes depending on the market environment, interest rates, business performance, and investment period.

Why do growth stock prices rise?

Stock prices are influenced not only by current profits but also by expectations for future profits.

For example, suppose the market thinks:

現在の利益: 100億円
↓
3年後の予想利益: 300億円

In this case, even if current profits are still small, stock prices may rise in anticipation of future profit expansion.

For growth stocks, in addition to current numbers, the future growth story is important.

However, this is also a dangerous place. If the market takes too much into expectations, stock prices may fall even if the financial results are not bad. When it comes to growth stocks, you need to look not only at whether the company is a good company, but also whether your expectations are too high.

Characteristics of growth stocks

High sales growth rate

Among growth stocks, there are companies whose sales increase by 10% to 30% or more each year.

However, it is safer to look at sales growth rates over multiple years rather than a single year. Even if there is a large increase for just one year, it may be due to acquisitions, temporary special demand, or price revisions.

Reinvest profits

Rather than paying out large dividends, growing companies may use their funds for investments such as the following:

Research and development *Capital investment
Recruitment
Advertising *M&A
Overseas expansion

Just because a company pays a low dividend doesn't mean it's a bad company. During the growth stage, it may make more sense to keep profits within the company and reinvest them.

However, whether reinvestment actually leads to profits is another matter. It would be best to take a careful look at a company whose losses continue to increase even though sales are increasing.

Tends to have a high PER

Even if a stock has a high PER (price/earnings ratio), it may be bought based on expectations for future growth.

For example, even if the P/E ratio is high, the stock price may be maintained if the market expects earnings to increase significantly in a few years.

However, stocks with high P/E ratios tend to decline significantly when expectations dissipate. It's not that a high P/E ratio itself is bad, but instead we check whether the growth that supports that P/E ratio continues.

Network effects

In SaaS, EC, SNS, and AI-related fields, the source of growth can be the network effect, in which the value increases as the number of users increases.

利用者増加
↓
データ・エコシステムの拡大
↓
サービス価値向上
↓
さらに利用者増加

However, once network effects are disrupted, trust can be rapidly lost, so we also check lock-in factors and substitutability.

Advantages of growth stocks

Expect a big price increase

If a company's sales, profits, and cash flow grow over the long term, its stock price can rise significantly.

Ten-baggers, or stocks whose stock prices increase tenfold, are often born from growing companies.

However, 10x stocks are not easy to find. You may experience big declines or long stagnation along the way.

May be resistant to inflation

Companies with the ability to pass on prices and expand markets may be more likely to grow in an inflationary environment.

For example, companies that have services that customers continue to use at higher prices, technologies that are difficult to replace, or products that are in growing demand may be better able to absorb rising costs.

Good compatibility with long-term investment

Great growth companies can continue to grow for more than a decade, not just a few years.

There are cases where it is easier to take advantage of the true power of growth stocks by holding them for the long term while watching business growth, rather than buying and selling them in the short term.

Disadvantages of growth stocks

Stock price fluctuations are large

The higher the expectations for growth stocks, the greater the disappointment.

Even with good financial results, the stock may decline if it does not meet market expectations. Conversely, even if a stock is in the red, it may be bought if its growth rate is high. It is also difficult for beginners to understand the reasons for price movements.

Good growth and bad growth

Sales alone is not enough to identify growth stocks. There are three things to look at: sales, profits, and cash.

Good growth
Sales increase
Profit increase
Increase in operating cash flow
Bad growth
Sales increase *Decrease in profits
Expansion of deficit

If these three factors are improving in that order, it indicates high-quality growth, but if profits and cash are deteriorating first, then you should be cautious.

Weak against interest rate rises

Growth stocks are stocks that are easily bought based on expectations for future profits.

When interest rates rise, the present value of future profits tends to be underestimated, which tends to be a headwind for growth stocks with high P/E ratios.

In particular, companies that still have small profits, companies that continue to invest in growth while in the red, and companies that rely on financing are likely to have their valuations lower when interest rates rise.

Drops due to underachievement

It is not uncommon for growth stocks to see their share prices fall by 20% to 30% after earnings are announced.

The reason is that high expectations are factored into the stock price. Even a slight slowdown in the sales growth rate may be seen as ``the growth story has collapsed.''

Tips for finding growth stocks

Sales growth rate

The first thing to look at is sales.

Check whether the growth is stable every year or whether the growth is temporary. If possible, I would like to look at trends over the next 3 to 5 years.

Profit margin

We look at whether not only sales but also profits are increasing.

Even if sales increase, if the operating profit margin continues to decline, the quality of growth may be weakening due to price competition, increased advertising expenses, increased personnel expenses, rising costs, etc.

Operating cash flow

There are companies that are making profits but not increasing cash.

Growth stocks can have weak operating cash flow due to accounts receivable, inventory, and upfront investments. The discrepancy between profits and cash is something you should always check.

Market size

No matter how hard a company tries, there are limits to growth if the market itself is shrinking.

Growth stocks look not only at a company's efforts, but also at whether there is room for growth in the industry as a whole.

Competitive Advantage

Check to see if your company has strengths that are difficult to imitate by other companies.

For example, technology, brand, network effects, switching costs, distribution channels, data, and regulatory compliance.

Management

For growth stocks, the long-term vision of management is also important.

The outcome for shareholders will vary greatly depending on whether a company widens its deficit by pursuing only sales growth or grows while keeping profits and cash in mind.

Mistakes that beginners often make

Mistake 1: Jumping on the stock after it goes up.

After it becomes popular, expectations can already be set high.

If you buy just because "everyone else is buying", you can easily get caught up in a situation where the stock goes down significantly due to a little bad news.

Mistake 2: Only look at sales

Sales growth is important.

However, it is difficult to call sustainable growth without profits. Profit over sales, cash over profit. Checking things in this order will reduce oversights.

Mistake 3: Concentrating your investment on one stock

Growth stocks can be unpredictable.

If you concentrate your funds in one stock, your overall assets will be seriously damaged due to disappointing financial results, intensified competition, scandals, failure to raise funds, etc. It is more realistic for beginners to prioritize diversified investment.

Mistake 4: Buying based on theme alone

Topics such as AI, semiconductors, cloud, and medical technology are fascinating.

However, even if the theme grows, not all companies will be able to make a profit. The popularity of the theme and the profitability of the company are considered separately.

Indicators to watch when investing in growth stocks

Indicators	Points to look at
Sales growth rate	Is it growing every year or is it a temporary factor?
Operating profit margin	Is profitability high or improving?
PEG	PER ratio relative to growth rate
ROE	Is shareholder capital being used efficiently
PER	Is it too high compared to growth expectations
Operating cash flow	Does profit come in as cash
Equity ratio	Is there financial strength
Research and development expenses/advertising expenses	Is it appropriate to invest in future growth?

Metrics do not stand alone.

For example, a high PER doesn't necessarily mean it's dangerous, and a low PER doesn't necessarily mean it's safe. Even a high P/E ratio can be valued if growth continues, and even a low P/E ratio can make it difficult for the stock price to rise if growth stops.

Compatibility with long-term investment

Investing in growth stocks tends to be more compatible with long-term holdings than short-term buying and selling.

The reason is that increasing corporate value takes time. Developing new products, acquiring customers, expanding overseas, and improving profit margins cannot be completed in one quarter.

It is important to keep an eye on the company's growth and not be swayed by short-term stock price fluctuations.

However, this does not mean that holding it for a long time will definitely pay off. When the growth story collapses, you need to reconsider your reasons for holding the stock.

If you try to find the perfect stock from the beginning, you will end up making poor decisions. First, we will check one by one why it is growing, where profits will be made, and what needs to be revised if it breaks down.

Common Misconceptions

Are growth stocks always profitable?

no.

If expectations are too high, the stock price may fall even if business performance is good. Growth stocks are an investment that searches for good companies, and at the same time, an investment that checks to see if the expected value is too high.

Are companies with no dividends bad companies?

No.

Growing companies may pay less dividends because they reinvest profits. However, it is necessary to check whether reinvestment is leading to profit growth.

Should I only own growth stocks?

If you focus only on growth stocks, your overall assets will fluctuate greatly when the market environment turns against you.

For beginners, it is easier to manage risk by combining growth stocks with ETFs, index funds, bonds, high dividend stocks, cash, etc.

If you can't narrow down your list of individual stocks, a practical way to start is by using ETFs or index funds with a high ratio of growth stocks. However, ETFs tend to fall when they specialize in themes, so it is important to decide in advance the purpose of stock diversification and revaluation rules.

Is it safe to buy growth stocks with NISA?

NISA is a tax system and does not eliminate the risk of the investment target itself.

Even if you buy with a NISA account, if the stock price goes down, you will end up with an unrealized loss. When holding growth stocks with a NISA, you need to consider price fluctuations, concentrated investment, and what to do in the event of a loss.

summary

Growth stocks are stocks of companies that are expected to increase sales and profits in the future.

The attraction is the potential for large price increases. On the other hand, there are also risks such as:

Stock price fluctuations are large *Easy to fall sharply due to underachievement
Vulnerable to interest rate rises
If expectations are too high, you will be sold even with good financial results.
Concentrating on one stock can easily lead to large losses

Beginners will find it easier to incorporate growth stock investing more realistically by keeping in mind the following order.

成長市場
↓
成長企業

利益とキャッシュ

分散投資

Growth stocks are a dreamy investment theme. However, it is dangerous to buy it just because you have a dream. It is realistic to check sales, profits, cash, competitive advantage, PER, and interest rate environment one by one and use them as part of the total assets.
