Yield Curve Interpolation with Gaussian Processes: A Probabilistic Perspective [Sitmo Machine Learning]Here we present a yield curve interpolation method, one thats based on conditioning a stochastic model on a set of market yields. The concept is closely related to a Brownian bridge where you generate scenario according to an SDE, but with the extra condition that the start and end of the scenarios must have certain values. In this paper we use Gaussian process regression to generalization

How Global Neutral Rates Impact Currency Carry Strategies? [Quantpedia]Market practitioners often rely on experience-based wisdom to navigate currency markets, and one such widely held belief is that low dispersion in global bond yields signals weak future returns for carry trades (and high dispersion implies high future carry returns). While this intuition makes sensewhen yield differentials are compressed, the incentive to exploit them diminishesa recent

Adverse Effects of Index Replication [Alpha Architect]Mutual funds and ETFs whose main directive is index replication incur adverse selection costs from responding to changes in the composition of the stock market because indices rebalance in response to composition changes (due to IPOs, delistings, additions, deletions, new seasoned issuance, and buybacks) to maintain a value-weighted portfolio. While this approach successfully tracks the index, it

The Growth and Inflation Sector Timing Model [CSS Analytics]big forces to worry about: growth and inflation. Each could either be rising or falling, so I saw that by finding four different investment strategieseach one of which would do well in a particular environment (rising growth with rising inflation, rising growth with falling inflation, and so on)I could construct an asset-allocation mix that was balanced to do well over time while being
