Weigh analyst notes, filings and short reports before you trade

An analyst upgrade arrives the same week as an insider sale. Earnings beat, guidance falls. The forum is bullish and a short report says fraud. You have no research desk, and you are sizing the position anyway.

What Arbiter does with that pile

You, or your AI assistant, list each source and what it claims. Arbiter then does three things.

Weighs each source by type. A regulator's filing starts with more weight than an anonymous post. The starting weights, and the reason for each, are published in the source-reliability table.
Lets old claims fade. A rumour from last quarter counts for less than this week's filing, so a stale story does not hold up a live thesis.
Keeps disagreement visible. When two credible sources contradict each other, the verdict says the question is contested. It does not average the two into a false middle.

The result is a verdict on each question with a confidence score, a status for each claim (supported, contested, not supported, or short of evidence, all judged against your sources), and a record you can reread after the trade: which sources carried the decision, and which did not.

What it will not do

Arbiter does not predict prices and does not read the market for you. It measures your sources against what they say. If every source you give it is wrong, the verdict is wrong too. It tells you how much weight your evidence can bear, not what the stock will do.
