Costain Group (LSE:COST) Net Current Asset Value Explanation
Benjamin Graham first discussed net current asset value (NCAV) in the 1934 edition of "Security Analysis", which he coauthored with David Dodd. In the book, (net) current asset value is defined as:" current assets alone, minus all liabilities and claims ahead of the issue."
The common definition of NCAV is: NCAV = current assets – [total liabilities + minority interest + preferred stock]
Net current assets exclude not only the intangible assets but also the fixed and miscellaneous assets. In addition, Graham believed that preferred stock belongs on the liability side of the balance sheet, not as part of capital and surplus. In "Security Analysis", preferred stock is dubbed "an imperfect creditorship position" that is best placed on the balance sheet alongside funded debt.
One research study, covering the years 1970 through 1983 showed that portfolios picked at the beginning of each year, and held for one year, returned 29.4 percent, on average, over the 13-year period, compared to 11.5 percent for the S&P 500 Index. Other studies of Grahams strategy produced similar results.
Benjamin Graham looked for companies whose market values were less than two-thirds of their Net-Net Working Capital. They are collected under our Net-Net screener.
