The number of buy transactions jumped from 544 to a whopping 1,275 in March, worth US$995 million. According to Smart Insider, this was the most buys in a single month since March 2020.

By sector, there's been a massive cluster in technology hardware stocks such as VSTECS, Hana Microelectronics, Suzhou Jinfu Tech and National Silicon Industry.
