RSSB is actively managed to provide simultaneous exposure to equities and a US Treasury futures strategy. The fund seeks to reflect the overall global equity markets on a market cap-weighted basis by investing in global equity ETFs, other broad-based ETFs, individual equity securities, and equity index futures. Underlying ETFs generally comprise 75 to 80% of the fund's portfolio. The fund provides indirect exposure to the US Treasury market by investing in futures contracts on US Treasurys with 2 to 30 years to maturity, with a target duration of 2 to 8 years. The fund will frequently roll futures, causing a high portfolio turnover rate. RSSB uses leverage to stack total returns of its two strategies. It targets a 100% notional exposure to investments in each strategy or an aggregate notional exposure of 200%. The fund holds US T-bills and cash equivalents as collateral.
