I just realized why many investors focus so much on Market Value, because it helps us understand the true worth of a company or asset, not just looking at the stock price today.

Market Value is the calculation of the total value of a company by multiplying the current stock price by the total number of shares outstanding. For example, if Company AAA has 300 million shares and the price is 1.50 baht, the market value would be 450 million baht. That's it, simple as that.

But what's important is that Market Value isn't just a random number; it tells us a lot, such as the size of the company, its importance in the market, and its investment potential. The higher the Market Value, the more significant and larger the company is in the market.

Several factors influence market value, such as the company's financial performance, the overall economic conditions, product and service quality, customer satisfaction, and liquidity. All of these affect whether the Market Value will be high or low.

One thing to watch out for is that Market Value is volatile all the time; stock prices change, and so does the Market Value. It’s not fixed. Also, it doesn’t tell us everything about the company, such as net profit, internal structure, or true assets.

It differs from Book Value, which is calculated from assets minus liabilities. Market Value is what the market currently accepts, which can be higher or lower than Book Value. For example, Company BBB has assets worth 500 million baht and liabilities of 250 million baht, so its Book Value is 250 million baht. But its Market Value might be 400 million baht if the market believes in its potential.

For investors, Market Value is very useful in decision-making. If we understand Market Value well, we can tell whether a stock is worth buying or not. The current price compared to the true value indicates if it’s overvalued or undervalued. That’s why professional investors need to deeply understand Market Value, not just look at the stock price today.
