A study of more than 550,000 wealthy Australian traders shows women outperformed men in high-conviction strategies by 7.5 percentage points last financial year, which for an average portfolio equated to an upside of $75,000.

“Overtrading” was one of the likely factors contributing to the underperformance of high-conviction strategies run by men, who traded 44 per cent more than women but had an average return of 0.73 per cent, according to research published by FinClear, which executes trades for major stockbrokers and platforms.
