(This is my opinion; someone is likely to disagee). I like to think of the carry as the predictable part (e.g. the coupon that accrues daily) and the rolldown as the stochastic part (the curves moved - maybe the forwards realized, maybe not. A good estimate of what it might turn out to be as to reprice for the next day assuming all forwards are realized. I ...

I'm assuming you're talking about a European option. I did a similar problem for my homework recently, I used the in-out parity for pricing the up and in barrier option. Basically European Option = Knock up and in Option + Knock up and out option You can price the up and out easily using Binomial and use BS formula for pricing the European Option, then ...

Another application in commodity trading is power transmission capacity. A power transmission line will be used to transport electricity from zone A to zone B if the price $p_A$ in zone A is smaller than the price $p_B$ in zone B, else it will remain idle. So the "payoff" of owning power transmission capacity $A\rightarrow B$ is $(p_B-p_A)^+$. This is a zero ...

Broadly you're asking about directional versus relative value strategies. There are lots of directional approaches, but I've yet to see many discussed publicly in non-generic ways (I mean, if they work, why would anyone talk about them?). As others have noted, trend following is a notable example. I'd consider a lot of equity factor approaches as a ...

Hi: It depends on what the DGP of the original process is. Is the process trend stationary or difference stationary ? If it's trend stationary then de-trending is the way to go. If it's difference stationary, then differencing is the way to go. The two models are quite different: Trend Stationary: $y_t = \beta_{0} + \beta_1 \times t + \epsilon_t$ ...

Under Black-Scholes assumption for the 2 assets $S_1$ and $S_2$ with volatilities $\sigma_{1,2}$ and correlation $\rho$ the value of this option has an explicit expression which is the Margrabe formula To quote the result explicitly Introducing $\sigma = \sqrt{\sigma_1^2 + \sigma_2^2 - 2 \sigma_1\sigma_2\rho}$, Margrabe's formula states that the fair price ...

Let me try to write formulae to explain the differences: When $X_t=a+b\,t + c\,\xi_t$, where $\xi_t$ is an iid centered and reduced noise (ie $\mathbb{E}\xi=0$ and $\mathbb{E}\xi^2=1$. With $X_(t+1)-X_t=b + c\Delta\xi$, you read that you increased the amplitude of the noise $\xi$ by a factor $\sqrt{2}$, you removed $a$ and you have no more time dependent. ...

This is pretty standard fare for a Stats 101 course, so as to rationale, etc. you might benefit from picking up a textbook or otherwise do some reading on this. In brief though, hypothesis testing allows us to assess the likelihood sample estimates are different than theorized values in the absence of actual population values. In the cases above, with a ...

If you exercise the option (assuming that is an american option) you would receive the intrinsic value, which is for a Call option $\max(S-K, 0)$, and for a Put option $\max(K-S, 0)$. Hence, 11300.00 - 11100.00 = 200. If you are talking about selling the option instead of exercising it, I recommend to have a look at the Black & Scholes model, John C ...

A portfolio is simply the collection of all assets you own. So in all your three cases, you still have a portfolio. In a Sense, a trading strategy is a synonym for portfolio in maths finance since you only need to know how much you invest at a certain time in a certain asset. For instance, your first scenario may be described by $(0,100,0,0....)$, i.e. you ...

Lots of different ways to do it that typically involve the following: (1) Identify starting universe. (2) Source and process underlying attribute data for each holding (for instance, for a low vol factor, possibly ST and LT vol for each security). (3) At this point, there is tons of variability. Once you have your factor data, some simply use it for ...

First you need to start with an investible universe of securities that can be used to retrieve data on. From there, you'll need to compile a list of each individual factor that you'd like to screen for (Momentum, Value, Growth, Div Payers, High Multiple, Asset Quality etc...) and create a metric of measurement for each factor. Enter into some sort of ...

As Alex C says in the comments, Longstaff and Schwarz did consider multiple factors and mention it as one of the advantages (page 114 in the journal): By its nature, simulation is a promising alternative to traditional finite difference and binomial techniques and has many advantages as a framework for valuing, risk managing, and optimally exercising ...

I would argue as follows: In order to observe any type of resonant behaviour, the dynamics of the system you are looking at needs to be described by a second order differential equation. The equations of motions that come to mind in economics are clearly not: GBM: $dS=\mu S dt+\sigma S dZ$ OU: $dX=\theta(\mu - X)dt+\sigma dW$

As an example of an instrument priced using Margrabe, Mexico government sold exchange warrants a few times in the past. The program's goal was to reduce hard-currency debt and replace it by local currency debt. An investor would pay some premium for the warrrants and have the right later to tender some face amount of hard-currency (and external-law) ...
