And here is SGX trying to encourage more of this type of trading here, which incidentally affects adversely (even if nothing goes wrong) other players esp retail investors. And meanwhile SGX is using SIAS to get heartlanders to play in the casino. I was present when Dr Goh Keng Swee called the stock market a casino.
I completely agree that the stock market has become a casino nowadays. HFT benefits no one except Wall Street. Greed (corruption) and humanity are inseparable.
The stock market are meant for the wealthy and the well informed players. If my company is a profitable one why should I want you people to come share with me the profits. It is only when I need funding then I will sell shares, bonds to prop up for my businesses. What may happen and what is happening is, well who knows, keep selling bonds and more shares………
