Aimed Bio, a KOSDAQ-listed company, rose sharply early on the 27th. The gains appear to be driven by buying on news that it will be added to major indexes including the KOSDAQ 150.

As of 9:19 a.m. that day, Aimed Bio was trading at 59,300 won, up 7,400 won (14.26%) from the previous session.

The Korea Exchange (KRX) said the previous day that Aimed Bio will be exceptionally added to indexes including the KOSDAQ 150, KRX Healthcare, KRX TMI, KRX Large & Mid TMI, and KRX Mid TMI. The index reconstitution is set for on the 13th of next month.

When a stock is added to an index, the likelihood of inflows from passive funds that track the index increases, and such expectations for a share-price rise appear to be lifting the current price.

Meanwhile, SELVAS AI, which will be removed from the KOSDAQ 150 index, fell 0.58% to 11,960 won at the same time.
