Vietnamese officials say they want to avoid those mistakes by keeping a tight rein on the Vietnamese market's growth.
Following last year's steep price rises, regulators limited the amount of buy orders that traders could place each day and cut the daily trading band for each stock. That scared off speculators, who began disposing their stocks, sending prices sharply lower.
The exchange has become more stable since the beginning of this year, but many investors remain disappointed.
"The market has not developed as quickly as I expected," said Hai, the brokerage firm head. "At first we expected a very big future, and that the future would come to us very quickly. Maybe it was just our enthusiasm."
Market officials say they're being held back now by cautious regulators in Hanoi, Vietnam's capital, who are reluctant to surrender their control over the fledgling market.
"The biggest problem is how to persuade the regulators in Hanoi to do the process faster," says Sinh. "We have to help everyone understand how a market operates -- the investors as well as the regulators."
