Explained: Why Rs 100 Stock Isn't Necessarily Cheaper Than Rs 5,000 Stock?

A Rs 100 stock can look like a bargain next to a Rs 5,000 stock. It costs just one-fiftieth as much per share, so the natural assumption is that there is more room for it to rise. That assumption, however, can be badly misleading.

The price displayed on a stock screen is only the price of one share. It does not tell you how large the company is, how much profit it makes, what its assets are worth or whether the stock is expensive relative to its earnings.

The National Stock Exchange's (NSE) investor handbook cautions investors against making decisions based simply on a stock's price. "Investing in very low-priced stocks or what are known as penny stocks does not guarantee high returns," it says. NSE also advises investors to take informed decisions by studying a company's fundamentals, including its business, future prospects, management quality and past track record.

So, what should investors look at instead?

Share Price Does Not Tell You a Company’s Size

Take two hypothetical companies. Company A has 1,000 crore shares trading at Rs 100 apiece. Its market capitalisation would be Rs 1 lakh crore. Company B has only 10 crore shares, but each share trades at Rs 5,000. Its market capitalisation would be Rs 50,000 crore.

The Rs 5,000 stock is 50 times more expensive than the Rs 100 stock on a per-share basis. Yet the company behind the Rs 100 stock is twice as large by market capitalisation.

This is because the number of shares matters. A company can have a low share price simply because its equity is divided into a very large number of shares. Another company can have a much higher share price with far fewer shares outstanding. It is like saying a Rs 50 lakh plot is cheaper than a Rs 2 crore plot without checking their sizes. The first could be a 500 sq ft plot, while the second could be a 5,000 sq ft plot.

The same principle applies to stocks. A share price cannot be viewed in isolation from the number of shares outstanding.

More importantly, company size and stock valuation are two different things.

A Rs 100 Stock Can Be Expensive

A Rs 100 share is not automatically undervalued, just as a Rs 5,000 share is not automatically expensive. This is where the difference between share price and valuation becomes important.

For example, let us take HDFC Bank and ICICI Bank’s share prices. As of the August 11 close, HDFC Bank traded at Rs 729 a share, while ICICI Bank closed at Rs 1,426. Yet HDFC Bank had a larger market capitalisation of around Rs 11.23 lakh crore, compared with Rs 10.26 lakh crore for ICICI Bank. The higher share price, therefore, did not make ICICI Bank the larger company.

In terms of valuation, HDFC Bank traded at around a 14.26 price-to-earnings ratio, or P-E, compared with nearly 18.32 P-E for ICICI Bank. This does not, by itself, make one bank a better investment than the other, but it only shows why investors should not judge a stock simply by its share price. Investors also need to look at how much they are paying for the company's earnings and what its future growth may look like.

Sebi's investor-education material says fundamental analysis examines a company's "financial health, growth potential and economic factors to determine its true value". It adds that analysing earnings, debt levels and industry growth can help an investor estimate whether a stock is "undervalued or overvalued".

That changes the question investors should be asking. Instead of asking, "How much does one share cost?", the more useful question is, "How much am I paying for the earnings and business that one share represents?"

Consider two more hypothetical companies. Company A trades at Rs 100 and earns Rs 2 per share. Its P-E is 50 times. Company B trades at Rs 5,000 but earns Rs 1,000 per share. Its P-E is only 5 times.

The Rs 5,000 stock costs 50 times more when you look at the quoted share price. But on an earnings basis, the investor is paying only 5 times annual earnings for it, compared with 50 times for the Rs 100 stock.

Sebi also identifies P-E, earnings per share (EPS) and debt-to-equity (D-E) as important metrics in fundamental analysis. It defines P-E as a ratio that compares a stock's price with its EPS.

A Low-Priced Stock Is Not Automatically A Bargain

There is another reason investors should be careful about judging a stock by its quoted price. It is a corporate action.

A company can split its shares, reducing the price of each share without changing the underlying value of an investor's holding in proportion to the split. For example, in a 1:5 stock split, one Rs 5,000 share could become five shares priced around Rs 1,000 each, assuming there is no market movement. The investor now owns more shares, but the total value of the investment remains broadly the same immediately after the split.

A recent example is Kotak Mahindra Bank. The bank carried out a 1:5 stock split in January 2026, with January 14 as the record date. One share with a face value of Rs 5 was split into five shares of Re 1 each. So, an investor holding 100 shares before the split would hold 500 shares after it, but the value of the holding would not become five times higher just because the number of shares increased.

This is another reason why a stock should not be considered cheaper simply because its price falls after a split.

Bonus issues can also alter the number of shares an investor owns and the quoted price without creating an equivalent change in the underlying value of the business. This is why a stock falling from Rs 5,000 to Rs 1,000 is not automatically more attractive than another stock trading at Rs 100.

Even market capitalisation, while useful for understanding a company's size, does not by itself tell investors whether a stock is cheap or expensive. For that, investors need to look at valuation in relation to earnings, cash flows, assets, growth and the quality of the underlying business.
