In the stock market, some microcap stocks trade below their book value, offering a different perspective on their valuations. The price-to-book (PB) ratio helps investors compare a company’s share price with its net asset value per share. A PB ratio below 1 indicates that a stock is trading at a discount to its book value. In contrast, a PB ratio of over 1 indicates that a stock is trading at a premium to its book value.
