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

Volatility isn't risk. Ruin is. Choose the price you'd pay. The filings give us a modeled floor. You decide how much of your portfolio can be wrong. That — not a chart — sets the size.

International Business Machines Corp is a Technology company.

Its floor is the earnings power floor, modeled from its filings: $101.00 a share.

At the prior close of $253.56 on 2026-10-23, that floor is 60.2% below.

With a 3.0% loss limit, your loss budget allows 5.0% of your portfolio, and business quality allows up to 7.1%. Your loss limit is the tighter constraint.

IBM position size FAQ

How much IBM stock should I own?

That depends on the price you would pay and the loss you can accept. At the prior close of $253.56 and a 3.0% loss limit, the calculator's maximum is 5.0% of your portfolio. It is a ceiling on size, not a recommendation to buy.

What is International Business Machines Corp's downside floor?

$101.00 a share: the earnings power floor, modeled from IBM'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 IBM capped at 7.1%?

Its quality composite is 0.421 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 59.5% of the 12.0% ceiling: 12.0% × 59.5% = 7.1%.

Does this tell me whether IBM is a buy?

No. It does not value the business. It sizes a position so one mistake cannot dominate your portfolio.
