Probably the most important part of investing is to understand the valuation of a company. A good understanding of valuation gives immense confidence to investors to buy and sell stocks in every opportunity of under and over valuation. It is that magic wand in investors hand that helps them to pick up a undervalued stock or average a falling stock with great confidence. Valuation is one and only parameter of utmost importance for investors that should guide them for entry, exit and holding strategies leading to dynamic portfolio management.However, as all important things in life, valuations of a stock too is a difficult nut to crack.

There are many complex mathematical formulas available like DCF and reverse DCF , which tries to assign a intrinsic value | fair value of a stock by projecting in the future earnings from the business. However they only works in ideal case scenario (*Considering everything else remains the same! ), which is never a reality given the dynamic nature of today’s businesses. So, valuating a company is a tricky job and requires  lot of understanding about different industries and the company to develop a qualitative understanding of about the valuation of the company under consideration. So, valuation today is more of a qualitative understanding and a gut feel with bit of stretch of imagination. It works to the level to understand if the stock is undervalued or overvalued or fairly valued to a great extent.

But to develop that understanding a investor got to look at different data points systematically to arrive at a conclusion about the valuation. In this blog series of understanding company valuations i’ll systematically take up different parameters one needs to look into, to develop the most important ‘gut feel’ about the stock.

The first should be to understand the concept of Market values Vs Book Value in greater details. We will deal with that in this blog post.

Market Values Vs Book Value

Understanding the difference between book value and market value is a simple yet fundamentally critical component of any attempt to analyze a company for investment. After all, when you invest in a share of stock or an entire business, you want to know you are paying a sensible price.

Book value literally means the value of the business according to its “books” or financial statements. In this case, book value is calculated from the balance sheet, and it is the difference between a company’s total assets and total liabilities. Note that this is also the term for shareholders’ equity. For example, if Company XYZ has total assets of Rs.100 and total liabilities of Rs. 80 , the book value of the company is Rs. 20. In a very broad sense, this means that if the company sold off its assets and paid down its liabilities, the equity value or net worth of the business, would be Rs.20

Market value is the value of a company according to the stock market. Market value is calculated by multiplying a company’s shares outstanding by its current market price. If Company XYZ has 10 shares outstanding and each share trades for Rs.50, then the company’s market value is Rs.500 . Market value is most often the number analysts, newspapers and investors refer to when they mention the value of the business.

Implications of Each

Book value simply implies the value of the company on its books, often referred to as accounting value. It’s the accounting value once assets and liabilities have been accounted for by a company’s auditors. Whether book value is an accurate assessment of a company’s value is determined by stock market investors who buy and sell the stock. Market value has a more meaningful implication in the sense that it is the price you have to pay to own a part of the business regardless of what book value is stated.

As you can see from our fictitious example from Company XYZ above, market value and book value differ substantially. In the actual financial markets, you will find that book value and market value differ the vast majority of the time. The difference between market value and book value can depend on various factors such as the company’s industry, the nature of a company’s assets and liabilities, and the company’s specific attributes. There are three basic generalizations about the relationships between book value and market value:

  1. Book Value Greater Than Market Value: The financial market values the company for less than its stated value or net worth. When this is the case, it’s usually because the market has lost confidence in the ability of the company’s assets to generate future profits and cash flows. In other words, the market doesn’t believe that the company is worth the value on its books. Value investors often like to seek out companies in this category in hopes that the market perception turns out to be incorrect. After all, the market is giving you the opportunity to buy a business for less than its stated net worth.
  2. Market Value Greater Than Book Value: The market assigns a higher value to the company due to the earnings power of the company’s assets. Nearly all consistently profitable companies will have market values greater than book values.
  3. Book Value Equals Market Value: The market sees no compelling reason to believe the company’s assets are better or worse than what is stated on the balance sheet.

It’s important to note that on any given day, a company’s market value will fluctuate in relation to book value. The metric that tells this is known as the price-to-book ratio, or the P/B ratio:

P/B Ratio = Share Price/Book Value Per Share

(where Book Value Per Share equals shareholders’ equity divided by number of shares outstanding)

So one day, a company can have a P/B of 1, meaning that BV and MV are equal. The next day, the market price drops and the P/B ratio is less than 1, meaning market value is less than book value. The following day the market price zooms higher and creates a P/B ratio of greater than 1, meaning market value now exceeds book value. To an investor, whether the P/B ratio is 0.95, 1 or 1.1, the underlying stock trades at book value. In other words, P/B becomes more meaningful the greater the number differs from 1. To a value-seeking investor, a company that trades for a P/B ratio of 0.5 implies that the market value is one-half of the company’s stated book value. In other words, the market is selling you each Rs.1 of net assets (net assets = assets – liabilities) for 50 paise. Everyone likes to buy things on sale, right?

Which Value Offers More Value?

So which metric – book value or market value – is more reliable? It depends. Understanding why is made easier by looking at some well-known companies.

Page Industries Ltd.

Page has historically traded at a P/B ratio of 20+. This means that Page’s market value has typically been 20 times larger than the stated book value as seen on the balance sheet. In other words, the market values the firm’s business as being significantly worth more than the company’s value on its books. You simply need to look at their income statement to understand why. Page is a very profitable company. Its net profit margin exceeds 12%. In other words, it makes at least 12 paise of profit from each rupee of sales. The takeaway is that Page has very valuable assets – brands, distribution channels,Loyal customers- that allow the company to make a lot of money each year. Because these assets are so valuable, the market values them far more than what they are stated as being worth from an accounting standpoint.

Another way to understand why the market may assign a higher value than stated book is to understand that book value is not necessarily an accurate value of a company’s net worth. Book value is an accounting value, which is subject to many rules like depreciation that require companies to write down the value of certain assets. But if those assets are consistently generating greater profit, then the market understands that those assets are really worth more than what the accounting rules dictate.

State Bank of India:

SBI is one of the oldest and largest banks in the India. It typically trades for a P/B of around 1, give or take a few percent. In other words, the market values SBI at or close to its book value. The reason here is simple, and it is explained by the industry SBI operates in. Financial companies hold assets that consist of loans, investments, cash and other financial securities. Since these assets are made of Rupees, it’s easy to value them: a rupee is worth a rupee. Nothing more, nothing less. Of course we know that some financial assets can be better than others; for example, a good loan versus a bad loan. That’s why whenever banks experience a financial crisis, as we saw in the subprime meltdown in 2008, their market values crash below book value. The market loses faith in the value of those assets.

On the other hand, financial institutions like HDFC Bank, which have a long history of extending out good credit, will trade at a modest premium to book value (only around 3+). Banks that the market views as having made bad credit decisions will trade below book. But in general terms, you will never see banks trading for multiples of book value like you would see in Page Industries, because of the nature of their assets in their books. You may financially account for a money value of the same for both, however their nature is never the same.

When the Values Matter

To determine how book value relates to market value, look at the income generated by the company’s assets. A company than can generate a relatively high income level from its assets will typically possess a market value that’s far higher than its book value. This is called the company’s return on assets, or ROA. Page Industries  ROA is typically around 40%  and around 6% for SBI. This means each Rupee of Page Industries assets generates 40 paise of profit, whereas for SBI it is just 6 paise. So, market has a very valid reason for paying a high value for Page and not SBI.

What this also means is that in the case of companies like Page Industries, book value is not as meaningful as it would be for a company like SBI.

The Bottom Line

Book value, like almost all other financial metrics, has its usefulness. But as is often the case with financial metrics, the real utility comes from understanding the advantages and limitations of book value. An investor must use that understanding to determine when book value should be used, and when it should be disregarded in favor of other meaningful parameters when analyzing a company.

In my next posts on this ‘Valuation Series’ i’ll talk about other such important parameters to look at to develop the understanding of stock valuations.
