Shares of Pinnacle Investment PNI.AX dropped as much as 7.1% to hit a more than one-month low after the company posted a fall in half-yearly earnings. Feb 2 (Reuters) - Australian shares rose on Thursday, tracking Wall Street after the Federal Reserve raised its interest rate by the expected 25 basis points, and as firmer bullion prices lifted gold stocks. The Fed said on Wednesday it had turned a key corner in the fight against high inflation, but that "victory" would still require its benchmark overnight interest rate to be increased further and remain elevated at least through 2023.
