$4.$ Active Bond Portfolio Management Using Futures You are a fixed income fund manager running a $$100$ million portfolio of a large pension client. According to your client agreement, you are performance benchmarked against the return on the S&P U$.$S$.$ Aggregate Bond Index. Your portfolio modified duration currently matches that of the Index, which you should assume is a modified duration of $5\mathrm{.}53$ years. Importantly, your client agreement provides you the discretion to actively vary your modified duration from $80$ to $120\%$ of that of the benchmark. Your forecast of market interest rates reveals an imminent decline in rates within the upcoming $3-4$ months or so$.$ To position your portfolio according to your view, you have decided to rebalance, but you do not have time to identify individual issues for purchase or sale nor do you wish to incur the liquidity costs of trading private placement holdings within your portfolio. Instead, you have decided to trade the appropriate September $5-$year T$-$note futures contract. Describe specifically what action you should take $($e$.$g$.,$ number of contracts, contract maturity, long or short$).$
