Summary: European and Asian stocks follow U.S. markets lower on Tuesday with Japanese and Hong Kong indices notching up losses, that mean they are down well over 10% from year-end highs, placing them firmly in "correction" territory. SoftBank is a lonely riser in Tokyo after a report suggested U.S. telecoms regulators probably wouldn't let its Sprint unit buy T-Mobile USA, while in Amsterdam weak fourth-quarter results push telecom KPN lower.
