Swiss October investor confidence index falls to -15.3 from 2.6

The swing from a positive reading to a firmly negative one in a single month points to a fast, sentiment-driven shift rather than a gradual erosion of confidence, which matters for a Swiss market that leans heavily on wealth management and financial services. The move is a survey of expectations, not a hard economic reading, so the signal is about mood among investors rather than realized flows. Whether this negative print proves a one-month reaction or the start of a sustained deterioration is the open question worth tracking.
