The Dax 40 tumbles as risk appetite subsides amid global policy tightening. The index has met stiff selling pressure at the origin of the late April sell-off at 14300. A drop below the psychological level of 14000 prompted buyers to bail out, invalidating the latest rebound in the process. A bearish MA cross is another sign that an imminent sell-off could be building up. A deeper correction below 13570 would send the price action to 13300. 13820 is a fresh resistance in case of a rebound.
