Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Key Terms

2 terms

average daily volume financial

"record year-to-date (YTD) average daily volume (ADV) of 11.0 million contracts"

Average daily volume is the typical number of shares or contracts of a security traded each day, calculated by averaging daily trading amounts over a recent period. It matters to investors because it indicates how easy it is to buy or sell without moving the price—like traffic on a road: high volume is a busy freeway that lets many cars pass smoothly, while low volume can make large orders cause big price changes and higher costs.

View in glossary

futures commission merchant financial

"a full-service Futures Commission Merchant and Notice Registered Broker-Dealer"

A futures commission merchant (FCM) is a licensed firm that executes and clears futures and options trades for clients, holds margin funds, and handles settlement and recordkeeping. Think of an FCM as the specialized broker and custodian for futures markets that also provides credit and risk controls; its reliability affects an investor’s ability to trade, the safety of their money, and the costs and speed of executing positions.
