SGX investigated and confirmed that the Straits Times Index (STI) did not reflect accurately the value of its components this morning. The index was 3,376.06 at the noon trading break, when it should have been 3,437.36, which was a difference of 1.27%. This was rectified from the start of the afternoon trading session.
We have traced this to an isolated computational error from the corporate action of a component stock. We have since resolved this, to prevent a recurrence of such an incident.
