DRSK provides fixed income and equity exposure in a single wrapper. The fund holds 90 to 95% of the portfolio in a 7- to 8-year ladder of USD-denominated, investment-grade corporate bonds, using bullet maturity ETFs to gain this exposure. DRSK holds these bond ETFs to expiration, rolling over each fund into a later-dated portfolio as it reaches maturity. The remaining 5 to 10% of the portfolio is invested in call options on US equities. Call options are purchased at the money, at least 6 months from expiration, and rolled quarterly. Options are purchased on 10 to 20 large-cap stocks chosen for momentum and growth potential, or on one or more ETFs tracking US large-caps. This option overlay effectively provides leveraged exposure to US equities, with a variable rate of leverage that increases when stock prices fall.
