Online investing in Australia continues to grow

online share trading

A new report from online share trading researcher Investment Trends has found that online investor numbers continued to rise in the second half of 2021.

The study shows a 21.6% increase to the number of online investors over the period, however this is still quite low compared to the 66.6% in 2020. 

However, even with lower numbers in 2021, Investment Trends’ head of research, Irene Guiamatsia says that Australia’s growth is pretty good.

“The growth in Australia was materially higher than rates observed globally, 21% growth compared to 16% growth in the US,” she said. 

This study that surveyed 19,508 investors and traders was conducted by Investment Trends between October and November 2021 found that the majority of the new investor cohort continues to be millennials and zoomers. 

“The report shows these younger investors have embraced the innovative product and pricing features on many emerging platforms,” Guiamatsia said.

It comes as no surprise that young investors are thriving in the online share trading space. Research commissioned by Commonwealth Bank last year found that 43% of millennials are actively investing their money as a way to later become financially independent.

CommBank also found that 63% of the one million new CommSec share trading accounts were held by millennials.
