Commonwealth Bank of Australia's stock soared 5.04% during intraday trading on Thursday, marking a significant upward movement for the banking giant.

The surge follows the bank's release of its half-year financial results, which included the announcement of an estimated fully franked interim dividend of A$2.35 per share. The upbeat results provided investors with fresh details on earnings and income following recent interest rate changes.

The positive financial update sparked a broader rally in Australian banking stocks, helping the S&P/ASX 200 index reclaim the key 9,000-point level. Market sentiment was buoyed by the bank's performance and dividend announcement, driving increased investor interest in the stock during the trading session.
