Fair value

How we estimate it

We don't publish a fair value for Bel Fuse. It needs a US-dollar share price, at least two valuation methods with positive inputs (earnings, EBITDA, book value or sales) and, for companies with several share classes, classes that trade at the same price.

An estimate from reported numbers and market multiples, not a price target or investment advice. It can be far off for companies whose profits are about to change sharply.
