By Kanishka AjmeraAug 4 (Reuters) - Recently listed U.S. shares of SK Hynix rose 5% after six brokerages started coverage of the South Korean chipmaker ‌with bullish ratings, citing its dominance in the booming AI memory ‌market and access to a broader global investor base. The American Depositary Receipts of SK Hynix, whose ​primary listing is in Seoul, were last up at $150.08 on Tuesday. At least six brokerages, including BofA Global Research, started coverage on SK Hynix with a "buy"-equivalent rating.
