interest rate. There's a probability of 30% the interest rate is going to
hike to 6%, and 50% probability its going to remain the same. There's 20%
chance interest rate will go down to 4%. Question is, will you take the
money now or later, and provide reasoning. |

如果0.2概率从5%涨到最高6%;0.5的概率remains 5%;0.2的概率hit 到最低4%。那么
这样是不是就抵消了;然后就跟5%一样。但剩下的0.1概率是上涨,所以我们期望说利
率会上涨? |

then V is a function of interest rate r.
The curve is convex.

You want to compare E[V[R]] with V[5.0%]
Jensen's inequality will only give you E[V[R]] >= V[E[R]] = V[5.1%]
So you need to calculate actual price or calculate bond convexity at 5.0% to
compare.My guess is that E[V[R]] > V[5.0%], meaning current price is cheap
and you should take the money later. i.e. invest money and take R% interest. |
