David is an average office worker. On KGI Securities website, he came across a company that was about to go public, issuing new shares to open public subscription. David compared the underwriting price (subscription price) with the market price and found that there was a 10% difference. He then decided to participate in the lucky draw through KGI Securities. Guess what? David won the lottery! When the stock was transferred to his account, the market price rose again, so David decided to sell it right away. It turned out that the net profit was 20%, which rewarded himself to a healthy profit
