Final Answer:
The 'Riding the yield curve' strategy is executed by buying bonds whose maturities are 1) Short-term.
Step-by-step explanation:
The 'Riding the yield curve' strategy involves buying bonds with maturities that are short-term. This strategy is based on the belief that short-term interest rates are lower than long-term rates, and by holding short-term bonds, investors can benefit from higher yields. As time progresses and the short-term bonds approach maturity, the investor can reinvest in new short-term bonds, taking advantage of potential increases in interest rates.
In this strategy, the focus is on the short-term part of the yield curve, exploiting the yield differentials between short and long-term bonds. It's not about buying bonds with medium or long-term maturities. Therefore, option 1) Short-term is the correct choice.
