I evaluated 53 different companies this week to determine whether they are suitable for Defensive Investors, those unwilling to do substantial research, or Enterprising Investors, those who are willing to do such research. I also put each company through the ModernGraham valuation model based on Benjamin Graham’s value investing formulas in order to determine an intrinsic value for each. Out of those 53 companies, only 15 were found to be undervalued or fairly valued and suitable for either Defensive or Enterprising Investors. Therefore, these 15 companies are the best undervalued stocks of the week.
