BT on Saturday reported that the loss-making social trading broker's initial public offering (IPO) drew roughly four-and-a-half times as many applications as there were shares in the public tranche.

Singapore private equity investor Luminor Capital has been the group's largest shareholder since 2014.

Ayondo was listed at a market cap of about S$130 million, and joins 74 other tech companies listed on the SGX. Taken together, these firms have a market cap of over S$84 billion.
