For some time, Western markets have been able to weather the clear slump in Asian stock markets. Now, the trend seems to have arrived in the US and Europe. All the major indexes have lost significant value over the past few days and especially Wednesday. The Dax is even close to falling below the important mark of 11,000 points again. The reason for this is concerns about the long-term economic development in the US but also the general concern that the long-lasting bull market on the stock exchanges is coming to an end.
