SK Hynix's American depositary receipts traded Friday under the temporary Nasdaq symbol SKHYV; CNBC says the symbol is scheduled to change to SKHY on Tuesday. [1]

That service detail completes one part of the paper's July 9 registration account, which said effectiveness supplied no final ticker, price or first trade; Friday now supplies the temporary symbol and the scheduled change, not proof that Tuesday's switch has occurred.

Markets discourse records the more celebratory fact that the shares opened at $170, about 14 percent above their $149 offer; that is separate from evidence that brokers have already mapped positions to the permanent symbol.

Investors looking for the stock before Tuesday therefore need SKHYV; after the scheduled change they should verify that Nasdaq and their broker show SKHY; CNBC's report does not provide an exact effective hour or guarantee every platform will display historical quotes identically; a completed debut and a future administrative switch belong on separate dates.
