The Australian Securities Exchange on Thursday refused to comment on speculation it was considering a bid for Iress Market Technologies, an Australian-listed market data and trading group in which it has built a 20% stake. Iress, which has a market value of close to A$1bn ($830m), last week said it could not explain a surge in its share price beyond bid rumours. ASX also reported a 14% drop in full-year pretax profits to A$445m in the year to June 30 on a 30% decline in the value of trading from the cash market.
