Markets are freaking out again – here's how to survive

After a short break, the eurozone has gone back to its job of spooking stock markets. Yesterday, the FTSE 100 fell 4.5%. And the Euro Stoxx 50 index – made up of the continent's top 50 shares – took another 5%-plus tumble. That wiped out much of the last few days' rally. In fact, this blue chip index is now over 25% lower than it was six months ago. Yet all the while we are being reassured by Europe's politicians that the single currency crisis has been sorted. Clearly it hasn't. Here's what this means for investors.
