Foreign investors net sell ¥66.5B of Japanese stocks in week to Oct 16

The headline number understates the story: the swing from prior-week net buying to net selling is what matters, since it signals overseas demand flipping direction rather than simply cooling. Foreign flow is a marginal but sentiment-heavy driver for Japanese equities, so a single week's reversal carries more narrative weight than its size suggests. The open question is whether this is a one-week pause or the start of a sustained exit; the next weekly flow print will be the first real test.
