The Commonwealth Bank has posted an eye-watering $2.6 billion unaudited first-quarter cash profit, buoyed by growth in home loans and deposits.

Despite the result putting Australia's biggest company on track to beat its record $10 billion 2025 full-year profit, investors dumped CBA shares, which tumbled 3.7 per cent to $168.51 in early trade.
