How Quanterix Stock Reacted to Its Q2 2026 Earnings, Measured Minute by Minute

The first headline of Quanterix's report carried the miss, and the first fifteen minutes carried the verdict: $4.04 to $2.74, -32.18%, measured from 12:00 UTC.

This page is the measured anatomy of that print on 10 August 2026: every earnings-related headline that crossed for Quanterix, in order, each with the price reaction measured from its own instant.

The print, row by row

Which line actually moved it

Each row above is measured from its own instant — the price immediately before that specific headline crossed — so the rows can be compared directly. The largest single reaction, -32.18%, belongs to the 12:00 UTC line. By the time the 12:03 UTC line arrived, the measured response was -23.08% — the marginal information in each successive headline decays fast, and the decay is measurable.

Did the first read hold?

It did. By the close of that session, Quanterix stood at -39.95% against the prior close — the same direction the first fifteen minutes priced. The instant read and the considered read agreed.

Nothing exotic here — a miss, priced as one. What the measurement adds is the speed: the gap between the print instant and the fifteen-minute mark is how long a reader of the headline had before the information was fully in the price.

How these numbers were measured

We record the price of the instrument immediately before each headline crosses our tape, then again one minute and fifteen minutes later, together with traded volume against that instrument's own normal. Every figure on this page comes from those recordings — the timestamps are the actual instants the lines crossed. Nothing here is an estimate, a close-to-close change, or a model's guess. The method, the gates every page must pass, and how we correct errors are documented in our editorial standards.
