SMBC and Toshiba Launch SMBC/TOSHIBA Quantum Driven Diversified Japan and U.S. Equity Indices
Sumitomo Mitsui Banking Corporation and Toshiba Corporation have jointly developed the SMBC/TOSHIBA Quantum Driven Diversified Equity Indices using Toshiba’s Simulated Bifurcation Machine. These indices select low-correlation stocks from major Japan and U.S. universes to maintain strong diversification even during market shocks. Quarterly rebalancing incorporates liquidity and transaction-cost controls while a joint patent is pending. The collaboration with S&P Dow Jones Indices opens the path to index funds, ETFs, and other commercial products.
