The founder of financial portal ShareInvestor.com died yesterday.
Dr Michael Leong, 54, had been battling colon cancer for more than a year.
The medical doctor-turned entrepreneur founded ShareInvestor in 1999 to provide real-time information on shares and other financial instruments.
He grew the portal before selling it to Singapore Press Holdings in 2008 for up to $18 million. Known as "oldman" to his online forum followers, he was an investment guru and had published two books: Be An Entrepreneur, and Your First Million - Making It In Stocks.
He was diagnosed with colon cancer in October 2014 after a routine colonoscopy. The doctor "found a small coin-sized cancer in the descending left side of my colon", he wrote on his online forum.
He had surgery to remove the cancer and started on chemotherapy.
A sliver of optimism showed in his post on Dec 12 last year when he said: "I appear to be on the road to recovery." This was after a scan showed that most of the cancer cells had disappeared.
Dr Leong graduated from Northern Ireland's Queen's University in 1985 with a bachelor's degree in medicine, surgery and obstetrics.
He is survived by his wife Irene and their two children.
