That erases the losses made this week, especially on Black Monday, when the biggest Chinese equities crash since 2007 rippled around the world.
That was partly on the back of a bit of positivity from China - the Shanghai Composite closed up 5.4%, the first rise it's had in six trading days.
Though they've been up and down, mining companies were today's big winners, with Anglo American shares surging 9.33%, and GHP up 9.21%.
Enterprise Inns shares fell 1.5%, the only decline of more than a percent of any stock listed on the FTSE 100.
Here's the chart:
European markets had a similar performance, with Germany's DAX up 3.2% and France's CAC 40 up 3.5%.
