Strategy in plain words
auto-generated from filingsMizuho Bank, Ltd. is a wealth-management firm allocating client money, specialised in financials (100% of the long book), running a $369.5M US long book across 4 positions.
The portfolio is extremely concentrated — the top 10 positions are almost the whole book. Turnover is high — positions rotate quickly, so individual names matter less than the process. Current anchor positions: SS ENERGY SELECT SECTOR, SS SPDR S&P 500 ETF TRUST-US, INVESCO DB AGRICULTURE FUND, CME GROUP INC.
Over the last 9 quarters its long book ran on average 0.5pp per quarter behind the S&P 500, beating the index in 5 of 9 quarters. Its holdings are mechanical (indexing / client flows), so position changes carry no stock-picking signal.
