Activist Retail Investors Take On Korea’s Corporate Laggards

South Korea’s small investors are trying to shake up the country’s creaky corporate landscape.

Amateur stock-pickers across the country are gathering on social media platform KakaoTalk and dedicated shareholder apps such as Act, which has racked up more than 110,000 users in the two years since it launched. Their aim: to give a jolt to Korea’s $1.9 trillion stock market, which has for years traded at cheaper multiples than regional rivals like Japan and Taiwan.
