comment Create optimal portfolio by Treynor and Jensens Alpha
If you make your metric Sharpe-like, by including a measure of distributional width in the denominator, then there is of course a reward. If that measure is standard deviation, then the mathematics even works out to be nearly identical to Markowitz.

comment Are Futures exactly Delta One?
Matt's usage of the term <i>forward delta</i> is important here. RRG (and Swab Jat) seem to be forgetting that delta has a denominator. That is to say, when we speak of the delta of a contract, we sometimes need to be explicit about what security that delta refers to (this is particularly obvious for exotics like basket options).

comment Topological methods in finance
Interesting premise: a market metric based on Jones polynomial! I wonder if its behavior differs much from standard correlation metrics. Based on your username, the paper is your own -- it would be polite to mention that in your answer.

comment A question about pricing convertible bond with two different underlying assets
You'll get a better-quality answer if you are more specific about the terms and conditions (T&C) of the bond. In particular, if the holder chooses to convert, is the mixture of assets the conversion happens into determined by the holder, the issuer, or a formula?

comment Usage of Brownian Bridge?
For scrambling, a good place to start would be Hinckernell's Quasi-Monte Carlo methods and their randomizations.

Use trees or other PDE discretization. Though you say they are "difficult" they are the right approach.

American exercise is precisely when you want to avoid using Monte Carlo.
