BANGKOK (AP) — Shares were mixed in Asia, while oil prices were holding steady Tuesday after jumping the day before as uncertainty persisted over when the Strait of Hormuz could reopen and get the global flow of crude going again. Brent crude oil was unchanged at $87.72 a barrel, while U.S. benchmark crude also was flat at $82.13 a barrel. South Korea’s Kospi gained 1.5% to 6,391.71 as shares in market heavyweight Samsung Electronics jumped 4.6%. Berkshire Hathaway, famous for buying stocks at what it considers low prices, gained 1.5%. The price of gold, often used as a hedge against risk in times of uncertainty, jumped 1.2% to 4,472.90 an ounce.
