    Japan’s net foreign investment in Japanese stocks fell to ¥-1B in the week ending 13 March. This was down from ¥385.5B in the previous period. The figure indicates a shift from net buying to net selling by foreign participants. The change was ¥386.5B between the two readings.

    Foreign Flow Reversal Risk

    This sudden reversal from a ¥385.5 billion inflow to a ¥1 billion outflow by foreign investors is a significant warning sign for us. The massive foreign buying that pushed the Nikkei 225 to record highs throughout 2025 may be exhausted. We should therefore reduce long-exposure and consider protective strategies. The sharp change in sentiment will likely cause a spike in market volatility. The Nikkei Volatility Index, which was trading near a calm 17 just two weeks ago, has already ticked up to 21, suggesting traders are pricing in bigger market swings. We should look to buy options, such as straddles or strangles, to profit from this expected rise in volatility regardless of market direction. Given this data, a bearish tilt in our derivatives positions is now warranted. We should consider buying Nikkei 225 put options with expirations in April and May to hedge against a potential market correction. After the market gained over 25% in 2025, a pullback driven by foreign selling is a high-probability scenario. We must also monitor the USD/JPY currency pair, which has been hovering around the 158 level. A flight of foreign capital from Japanese equities could lead to yen strength as investors sell their stocks and convert the proceeds, creating an additional headwind for Japanese exporters. We can use options on the yen to hedge this currency risk or speculate on its appreciation.

    Key Follow Through Signals

    This outflow reminds us of the brief profit-taking we observed in mid-2025 when concerns about Bank of Japan policy tightening first emerged. However, the market is now at a much higher valuation, making it more vulnerable to a sustained downturn if these outflows continue. We need to watch the foreign investment data for the week of March 20 very closely to see if this is a one-time event or the start of a new trend.
