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.

Net operating profit financial

"Net operating profit | Specified Quarter"

Net operating profit is the money a company keeps from its regular business activities after paying the costs needed to run the business — such as wages, rent and supplies — but before profits or losses from financing or one‑time events. Think of it as the cash left in a household budget after paying recurring bills; investors watch it to judge whether the core business is healthy and likely to generate sustainable returns.
