Why today’s larger movers moved could not be confirmed in this morning’s data; each is still marked as having no identified driver.No cause is attached here. Once flows and disclosures are filled in after the close, they will be looked at again.Market breadth did not arrive today either — the exchange data source is blocked. The last confirmed reading is 2.02 for KOSPI, dated 24 August, with no value for the three sessions since. Whether today’s gains belong to the whole market or to a few names therefore cannot be separated.
