South Korea’s benchmark KOSPI index climbed past the 7,000 level for the first time, setting a new all-time high as gains in semiconductor stocks drove the broader market sharply higher.

According to the Korea Exchange, the KOSPI opened at 7,093.01 on May 6, up 2.25% (156.02 points) from the previous session. The rapid rally triggered a buy-side sidecar early in the session, temporarily halting program buy orders.
