Usage & Application
How to Use This Book
Here’s how to put Graham’s playbook to work today.
First, if you’re evaluating a dividend stock, build a simple owner’s earnings model, haircut growth by 30%, and check interest coverage and payout ratios. If the implied yield under conservative assumptions is still attractive, you’ve likely found value.
Second, when screening corporate bonds, filter for interest coverage >4x, net debt/EBITDA <3x, and strong covenants, then price in a default spread consistent with recessionary stress.
Third, in small-cap research, anchor on tangible book, normalize margins to 5-year medians, and demand a 25–40% discount to your base-case valuation. This process improves win rates, reduces downside, and keeps you from chasing narratives.
Start small: pick one sector, document assumptions, and require a margin of safety before you hit “buy.”
