Japanese Stock Investment by Foreigners (Aug/01) -392.5

Weekly MOF flow data of this kind is a soft gauge rather than a market mover on its own; a net foreign selling print of this size sits well within the normal range for the series and historically only moves the yen or Nikkei when it extends a multi-week trend or coincides with a broader risk episode. The distinction worth drawing is between a one-off negative reading, which episodes of this kind have tended to show is noise around month-end and rebalancing dates, and a sustained run of foreign outflows, which has in the past signalled a shift in the overseas sponsorship that has underwritten the Japanese equity rally. The companion series, Japanese investment in foreign bonds and stocks, matters as much for the FX read, since the net portfolio flow and the hedging behaviour behind it is the transmission channel into the currency rather than the equity line alone. Worth noting is whether subsequent prints confirm a pattern and whether the selling is concentrated in cash equities or futures-driven. As a single weekly print, the signal is weak.
