Louie Shum Chun-ying (沈振盈, "Master Shum")

On the evening of 24 October 2026, after dining at a friend's home in Wan Chai, Shum collapsed at a taxi stand on Lockhart Road at a little after 7 pm. Passers-by called the police and paramedics took him to Ruttonjee Hospital, where he died at about 9 pm. He was 65. The cause of death has not been made public.

His younger sister, Shum Chun-shan, announced his death on 25 October in a notice to his students, saying he had devoted his life to Hong Kong's financial and securities industry and that funeral and memorial arrangements would be announced later. He had co-hosted a RagaFinance programme as recently as 23 October, and many followers came to see that broadcast as an unplanned farewell. News of his death brought a wave of tributes online.

Louie Shum Chun-ying (沈振盈) was born in British Hong Kong on 27 June 1961. His family's ancestral home was Panyu, in Guangdong province. He attended Sun Fat College, finishing primary school there in 1977, where his classmates included Eddie Yue, who later became chief executive of the Hong Kong Monetary Authority, and completed Form Five in 1982.

He went on to the Faculty of Business Administration at the Chinese University of Hong Kong, graduating in 1987 with a major in management and a minor in finance.

Shum later admitted that he knew almost nothing about shares when he graduated, but he chose the securities industry and joined a brokerage as a management trainee. The stock market crash of October 1987 pushed him out of finance for a time, and he worked in marketing for a trading company and a fast food chain before returning to broking in 1992.

He headed the research department at Emperor Securities and spent most of his career at Sincere Securities (formerly Tse's Securities), where he was a licensed responsible officer and served for many years as chief executive. From 2000 to 2015 he wrote a stock market column, Practical Theory, for Apple Daily, and from 2006 he appeared from time to time as a guest analyst on the TVB market programme Trading Floor (交易現場). He co-hosted the online programme 錢錢錢打到嚟 on RagaFinance, presented the am730 web show 講升講跌, and in 2021 hosted 有錢淘 on TVB's finance and information channel. He also ran investment courses whose former students formed a large and loyal community.

His forecasts made him one of the most talked about commentators in Hong Kong. In 2007, as the Hang Seng Index was rising, he told investors to hold not a single share. The call drew years of ridicule on the Golden online forum, where users dubbed him Master Shum, Judge Shum and the Lamp Genie and treated his calls as a contrary indicator. Shum blamed organised critics for the attacks and maintained that he was right about eight times in ten.

In 2019 the Securities and Futures Commission fined Sincere Securities HK$5 million over internal control failures. On 31 January 2024 Shum retired as chief executive, citing the pressure of the job and a mild stroke two years earlier, but he continued as a commentator and host in semi-retirement.

Shum was married; Chinese Wikipedia names his wife as 江婉瑩. He lived in several parts of Hong Kong over the years, including Tsuen Wan, Tseung Kwan O, Ma On Shan, Hung Hom and Mei Foo, and once said he would rather rent all his life than buy property at the top of the market. Fellow commentator Kwok Sze-chi described him as warm-hearted and unpretentious with younger colleagues, and said the online attacks on him had been unfair.

For more than two decades Shum was part of the daily rhythm of Hong Kong's retail investing culture. Some investors relied on his views, others treated them as a warning sign, but few ignored them, and his blunt, image-rich catchphrases became part of the city's market slang. As a columnist, broadcaster and teacher he introduced many ordinary investors to the stock market.
