How it works

Small cap stock alerts: how PREZLO finds them

By Omri Ben David, founder of PREZLO · September 13, 2026

We built PREZLO to watch the whole US market in real time and send you an alert when a small cap stock starts showing unusual price and volume changes. This page explains exactly what that means, and what it does not mean.

What we watch

From 4:00 AM Eastern, before the market opens, PREZLO receives every trade in every US-listed stock, second by second, from a direct market data feed. We do not watch a hand-picked list. We watch everything, and we look for the small ones. Every alert card then shows how small the company really is, with its market cap, float and short interest.

What has to happen before an alert goes out

Two things, at the same time. The volume has to be unusual for that stock, compared with how much it normally trades. And the price has to be moving, not sitting still on a burst of trades. A stock that is loud but flat does not pass. A stock that is up on thin volume does not pass. Both, together, pass.

The exact numbers behind "unusual" are ours and we keep them to ourselves. What we can say is that they are strict on purpose. Most days the whole market produces only a handful of alerts. If PREZLO sends you something, it is because a real screen was passed, not because a stock was mentioned somewhere.

What the alert looks like

The push notification tells you something is moving and asks you to open the app. It does not name the stock. Inside, the alert opens as a card:

A PREZLO alert card with sentiment estimate, market cap, float and short interest

An alert card in the app.

Every alert stays in the record

Record, inside the app, keeps a running log of the alerts we sent.

What we never do

What an alert is not

An alert is not a prediction. Small caps can move sharply in both directions, and prices can reverse quickly. Read what unusual volume actually tells you and why pre-market moves are different before you act on one.
