Shares in Jardine Fleming had a flash crash yesterday, dropping 80+% in pre market trade before coming right back up again
SGX says
- neither a fat finger nor a malfunctioning computer system were responsible
- there was no evidence of manipulation
- trading was orderly
SGX reviewed trades, and has let them all stand - sellers as it fell had "ample time" to withdraw their orders if they didn't want to offload shares at the low price
The Singapore exchange does have circuit breakers, but only during regular trading hours. That might be something to have a look at.
