What GemRadar does

GemRadar looks for stocks where several independent signals point the same way while the price does not yet reflect it. It surfaces candidates to look at. It does not tell you what to buy.

The sweep

Every trading day, before the US market opens, GemRadar runs a full pass over every sector on NASDAQ and NYSE within a market-cap band of $300M to $5B. That is roughly 430 stocks a day, and nothing in that list is hand-picked — the universe is defined by rules and swept in full, so a stock cannot be quietly left out because it was inconvenient.

For each one it gathers three things:

• Insider conviction — did people inside the company buy shares with their own money in the past twelve months?
• Analyst valuation — how do the published ratings and the forward P/E compare?
• Market behaviour — how easily does this stock actually trade?

Those become one Divergence Score between 0 and 100, and the day's list is ranked by it.

Why divergence

A single strong number is easy to find and usually already priced in. What is harder to find, and more interesting, is disagreement: insiders buying while analysts stay silent, or a valuation that looks cheap on a stock nobody is watching. The score is built to notice that shape.

It is not a prediction. Please read what the score cannot tell you — it is the shortest path to using this well.

The record

Every stock GemRadar flags is recorded on the day it is flagged, with its score and its price. The track record then measures what became of all of them — including the ones that went nowhere and the ones that fell. The denominator is always on screen, because a list of winners with no denominator is a brochure rather than evidence.

What it is not

Not a broker: you cannot trade through it. Not an adviser: it does not know your situation and never asks. Not a signal service: there are no buy alerts. It is a screen with its reasoning written down.
