ein immenser Unterschied, ob etwas aus kurzfristig psychologischen Gründen erfolgt oder dauerhaft, aufgrund von wirtschaftlichen Marktmechanismen (zB Sentiment, an das Du ja auch nicht glaubst):
"Why Didn’t the Stock Market Fall During the Taper Tantrum?
There were many reasons for the stock market's continued health. For one, following Chairman Bernanke’s comments, the Fed did not actually slow its QE purchasing, but instead launched into a 3rd round of massive bond purchases, totaling another $1.5 trillion by 2015. Secondly, the Fed professed a strong faith in market recovery, boosting investor sentiment and actively managing investor expectations through regular policy announcements. Once investors realized that there was no reason to panic, the stock market leveled out."
