Australian shares ended flat on Thursday after the country's third and fourth-largest telecom operators announced a merger, creating a heavyweight challenger to the top two providers.
TPG's shares climbed 18 per cent, while Hutchison sky-rocketed 44 per cent and Telstra shares added 2.9 per cent.
Despite the likelihood of increased competition from the merger, "the market seems to have taken the total opposite view to that for some reason," said James McGlew, executive director of corporate stockbroking at Argonaut.
"This is going to lead to a decrease in competition for Telstra and either way the market is embracing a sector that has been in the doghouse for a while. It just shows you how contrarian markets can be at times."
