### Cochrane on Return Predictability

Maybe I am a little bit late to the party, but I want to give a shot. As in Campbell and Shiller, start from the identity $R_{t+1}\equiv\frac{P_{t+1}+D_{t+1}}{P_t}$ where $R_{t+1}$ is the gross return ...

### Why does the YTM equal the coupon rate at par?

Let $P$ denote the dirty price, $F$ the face value and $i$ the YTM. Using the geometric sum we get \begin{align} P &= \sum_{j=1}^n \frac{C}{{(1+i)}^j} + \frac{F}{(1+i)^n}\\ &= C\frac{1-\...

### Constructing yield curve directly from yield-to-maturity data

Unless all of your yields are par yields (yield of bonds trading at par), you'll get very unreliable results if you fit your curve using yields alone. This is because yields can be distorted by the ...

c is the coupon of the bond, so it is paid semiannually. You can see this from the LHS of the first equation, which is the sum of present values of the coupons and principal. The 6.87 and the 6.75 ...

### Why does the ultra long-end of a yield curve invert?

I would not say that this is universally acknowledged but here is my view: Instead of considering par rates, i.e. 10Y and 20Y, consider forward rates, such as 10y and 10y10y. The useful difference ...

### Calculating coupon yield and continous compounding

Hint: Let $$z = \mathrm{e}^{-y}$$ That way you get a quadratic equation in $z$ (note that $z$ is positive) and then you can get back to $y$ using: $$y = -\ln (z)$$
