Markets are plunging again
Poor economic data from China has sent people running from stocks.
China's official measure of manufacturing activity fell to 49.7 from 50.0 in July - the fastest pace of contraction since August 2012.
European economies have also reported some terrible economic data.
Here's the European share market scoreboard:
UK's FTSE: -2.19%
Germany's DAX: -2.72%
France's CAC40: -2.42%
Spain's IBEX: -2.12%
And this is what's happened to the Euro Stoxx 50, which is an index of Europe's biggest publicly listed companies. It's currently down 2.65%:
