It’s been a very good day for Asian stock investors, particularly in Japan.

Boosted by strong leads from US and European markets on Friday, along with the prospect of additional fiscal and monetary stimulus in Japan, stocks across the region soared on Monday with every major index recording strong gains.

Most of the activity was concentrated in Japan with the Nikkei 225 soaring 4%, its largest one-day percentage gain seen since early March.

There were also large gains of 2% and 1.6% registered in Australia and South Korea.

Stocks in Singapore, Hong Kong and mainland China are also on track to finish firmly in the black.
