Foreign investment in Japanese equities swung to a net inflow of ¥479.4bn for the week to 19 June, reversing the prior week’s net outflow of ¥-785.1bn. The shift marks a change in cross-border positioning in Japan’s stock market over the latest reporting period.
The data indicate foreign flows moved from net selling to net buying within a week, with the balance turning positive by ¥1,264.5bn compared with the previous reading. The figures refer to foreign transactions in Japan-listed shares for the respective weeks.
Rebound In Foreign Sentiment And Bullish Market Outlook
We are seeing a major reversal in sentiment towards Japanese stocks, with foreign investment swinging from heavy selling to a net inflow of ¥479.4 billion. This is a very strong buy signal, suggesting international investors are now positioning for a significant move upwards. This sharp turnaround in capital flows is the primary catalyst for our bullish outlook in the coming weeks.
Given this powerful buying pressure, we should consider purchasing call options on the Nikkei 225 to directly participate in the expected rally. The index has already climbed over 2% to 40,150 in the past week, confirming that momentum is building. This initial strength suggests the trend is just beginning and has room to run.
Investment Strategies And Yen Impact
The steady inflow of capital may also suppress market anxiety, making it a good time to sell out-of-the-money put options on key Japanese indices. The Nikkei Volatility Index has fallen to 16.2, near its lowest level for 2026, which indicates that option premiums are attractive for strategies that profit from a rising or stable market. This approach allows us to collect income while maintaining a bullish stance.
This level of investment in Japanese stocks will almost certainly strengthen the Yen, as foreign buyers must convert their currency. We should therefore consider positions that benefit from a lower USD/JPY, such as buying puts on the currency pair, which is currently trading around 154. This view is reinforced by the Bank of Japan’s recent signals that it is ending its negative interest rate policy for good.
Historically, sustained periods of strong foreign inflows have kicked off multi-month rallies in Japanese markets, reminiscent of the 2013-2014 period. That rally saw the Nikkei surge over 50% on the back of foreign capital. We are therefore also exploring longer-dated futures contracts to capture what could be the start of a similar extended uptrend.
