5 Undervalued Price-to-Book Stocks Worth Adding to Your Portfolio

Price-to-book ratio, or P/B ratio, is essentially the ratio of stock price to book value, i.e., how much an investor needs to pay for each dollar of book value of a stock. It is calculated by dividing the current closing price of the stock by the latest quarter's book value per share.In value investing, it is a common practice to pick stocks that are cheap but fundamentally strong. There are a number of investment styles for finding great stocks at attractive values.While considering valuation metrics, though price-to-earnings and price-to-sales are the first choices, the P/B ratio is also emerging as a convenient tool for identifying low-priced stocks that have high-growth prospects.Here’s the formula of P/B ratio:P/B ratio = market capitalization/book value of equity.This metric can help identify attractively priced stocks with upside potential. Some such stocks are Harmony Biosciences Holdings HRMY, Invesco IVZ, General Motors GM, Hewlett Packard Enterprise HPE and Quanex Building Products NX. Let us understand the concept of book value.What is Book Value?There are several ways in which book value can be defined. Book value is the total value that would be left over, according to the company’s balance sheet, if it went bankrupt immediately. In other words, this is what shareholders would theoretically receive if a company liquidated all its assets after paying off all its liabilities.It is calculated by subtracting total liabilities from the total assets of a company. In most cases, this equates to common stockholders’ equity on the balance sheet. However, depending on the company’s balance sheet, intangible assets should also be subtracted from total assets to determine book value.Book Value Per Share = (Total Assets – Total Liabilities) ÷ Number of Outstanding SharesUnderstanding P/B RatioBy comparing the book value of equity to its market price, we get an idea of whether a company is under- or overpriced. Like P/E or P/S ratios, it is always better to compare the P/B ratio within industries.A P/B ratio of less than one means that the stock is trading at less than its book value or the stock is undervalued and, therefore, a good buy. Conversely, a stock with a ratio greater than one can be interpreted as being overvalued or relatively expensive.For example, a stock with a P/B ratio of 2 means that we pay $2 for every $1 of book value. Thus, the higher the P/B, the more expensive the stock.But there is a warning. A P/B ratio of less than one can also mean that the company is earning weak or even negative returns on its assets or that the assets are overstated. In such a case, the stock should be shunned because it may be destroying shareholder value. Conversely, the stock’s price may be significantly high — thereby pushing the P/B ratio to more than one — in the likely case that it has become a takeover target, a good enough reason to own the stock.Moreover, the P/B ratio is not without limitations. It is useful for businesses like finance, investments, insurance and banking or manufacturing companies with many liquid/tangible assets on the books. However, it can be misleading for firms with significant R&D expenditure, high debt, service companies, or those with negative earnings.In any case, the ratio is not particularly relevant as a standalone number. One should analyze other ratios like P/E, P/S and debt to equity before arriving at a reasonable investment decision.Screening ParametersPrice to Book (Common Equity) less than X-Industry Median: A lower P/B compared with the industry average implies that there is enough room for the stock to gain.Price to Sales less than X-Industry Median: The P/S ratio determines how much the market values every dollar of the company’s sales/revenues — a lower ratio than the industry makes the stock attractive.Price to Earnings using F(1) estimate less than X-Industry Median: The P/E ratio (F1) values a company based on its current share price relative to its estimated earnings per share — a lower ratio than the industry is considered better.PEG less than 1: PEG links the P/E ratio to the future growth rate of the company. The PEG ratio portrays a more complete picture than the P/E ratio. A value of less than 1 indicates that the stock is undervalued, and investors need to pay less for a stock that has bright earnings growth prospects.Current Price greater than or equal to $5: They must all be trading at a minimum of $5 or higher.Average 20-Day Volume greater than or equal to 100,000: substantial trading volume ensures that the stock is easily tradable.Zacks Rank less than or equal to #2:Zacks Rank #1 (Strong Buy) or 2 (Buy) stocks are known to outperform irrespective of the market environment.Value Score equal to A or B: Our research shows that stocks with a Value Score of A or B, when combined with a Zacks Rank #1 or 2, offer the best opportunities in the value investing space.5 Low Price-to-Book StocksHere are five of the 16 stocks that qualified for the screening: Delaware-based Harmony Biosciences is a neuroscience company developing and commercializing therapies for sleep/wake disorders and rare neurological diseases.Harmony Biosciences currently has a Value Score of A and a Zacks Rank #1.
