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.

International Financial Reporting Standards financial

"in accordance with International Financial Reporting Standards as adopted in Korea"

International Financial Reporting Standards are a common set of accounting rules used by companies in many countries to prepare and present their financial statements. They matter to investors because they make results easier to compare across borders — like using the same measuring tape — so investors can assess profitability, cash flow and risk more reliably and spot differences that come from business performance rather than differing accounting methods.
