A sell-off of tech stocks is accelerating in Asia, with SoftBank dropping 6%. The decline appears to be part of a broader market trend, with other stocks and indices, including those in the semiconductor sector and the UK, also being affected. The extent of the sell-off and its impact on various markets is still unfolding, with reports of significant declines in some areas, such as an 11.5% plunge in SK Hynix.
