How much STE 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.
STERIS plc is a Healthcare company.
Its floor is the earnings power floor, modeled from its filings: $198.00 a share.
At the prior close of $232.15 on 2026-10-23, that floor is 14.7% below.
With a 3.0% loss limit, your loss budget allows 20.4% of your portfolio, and business quality allows up to 8.2%. Business quality is the tighter constraint.
STE position size FAQ
How much STE stock should I own?
That depends on the price you would pay and the loss you can accept. At the prior close of $232.15 and a 3.0% loss limit, the calculator's maximum is 8.2% of your portfolio. It is a ceiling on size, not a recommendation to buy.
What is STERIS plc's downside floor?
$198.00 a share: the earnings power floor, modeled from STE'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 STE capped at 8.2%?
Its quality composite is 0.549 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 68.4% of the 12.0% ceiling: 12.0% × 68.4% = 8.2%.
Does this tell me whether STE is a buy?
No. It does not value the business. It sizes a position so one mistake cannot dominate your portfolio.
