How much DD fits your loss budget if the floor holds?

DD position size FAQ
How much DD stock should I own?
That depends on the price you would pay and the loss you can accept. At the prior close of $136.55 and a 3.0% loss limit, the calculator's maximum is 5.8% of your portfolio. It is a ceiling on size, not a recommendation to buy.
What is DuPont de Nemours, Inc.'s downside floor?
$103.00 a share: the book value floor, modeled from DD's filings and recomputed 2026-10-23. Banks and insurers are held to book value; every other business to its earnings through a full cycle. A floor is a model, not a bound: the price can trade through it.
Why is DD capped at 5.8%?
Its quality composite is 0.266 on a 0–1 scale, built from five ratios in its annual reports and graded against all companies, not just its sector. That composite keeps 48.6% of the 12.0% ceiling: 12.0% × 48.6% = 5.8%.
Does this tell me whether DD is a buy?
No. It does not value the business. It sizes a position so one mistake cannot dominate your portfolio.
