Answer:
The book value of the stock can be calculated by taking the difference of assets and liabilities and then dividing the answer by the number of shares. The result will be the book value of a unit stock. Whereas the market value of the share is different because the stock market valuates the stock which is dependent on its assets, return, riskiness of the industry, social responsibility, etc. So these factors helps companies like S & P global, Dow's plc, etc to value stocks and publish the credit ratings of companies in stock exchange.
Step-by-step explanation:

The book value of the company is negative but still the company has a great number of profits for the year and the company is worth $300 billions.
