This research summary presents a macro timing framework for Chinese equities and bonds built around monetary conditions and credit growth. It treats policy shifts as potentially informative because monetary policy is described as delayed and constrained by…
This report describes using Campisi and Brinson models to analyze the performance and investment styles of bond funds, with fund selection for fund-of-funds managers as the motivation. It notes that bond fund valuation and disclosure challenges make…
The post raises a research question about obtaining daily exchange-rate data for several countries, including China, the United States, and Japan. Its author argues that broad equity-market timing should consider capital flows, distinguishing domestic flows…
The document outlines ways to set the changing asset allocation, or glide path, of a target-date fund. One approach uses an investor’s human capital and forecasts of future asset returns to choose a path that maximizes investor utility. Another bases the…
This Chinese market note proposes that China’s credit impulse may be turning upward and argues that it tends to lead A-share earnings growth. On that assumption, it recommends overweighting Chinese equities, favoring growth over value, and ranking…
This weekly market note responds to weakening Chinese equity sentiment and increased uncertainty by reducing A-share exposure, adding interest-rate bonds and secondary bond funds, and increasing exposure to low-valuation and dividend factors. Its rationale…
This report introduces over-the-counter options as privately negotiated, nonstandard contracts and describes spread strategies built from multiple options on the same underlying. It names bull, bear, and butterfly spreads as examples. The central pricing…
This Chinese language summary reports findings from a study of passive and active strategies across asset classes in the United States, United Kingdom, and Japan over a long historical period. It frames the analysis as useful because recent experience in…
The document explains how to estimate a bond’s value by discounting each scheduled coupon and principal payment. It adds the bond’s z-spread to the relevant spot rate, uses the resulting rates to calculate discount factors, and sums the discounted cash…
The document examines how Actual/Actual ISMA determines coupon amounts for a fixed-rate bond with a short or long stub period. Its example has a first coupon running from the issue date to a February payment date, followed by monthly coupons. The initial…
The document derives an alternate form for the time integral of Brownian motion, a step that arises in the short-rate Merton model. Representing Brownian motion at each time as the accumulation of its increments turns the time integral into an integral over…
The document frames a model-selection problem for reinforcement-learning-based dynamic hedging of long-dated swaptions. The proposed application uses 2y2y and 4y2y swaptions, requiring simulated paths that update both a forward swap curve and an implied…
The document discusses how to interpret a LIBOR Market Model matrix when constructing discount bond values. It emphasizes that matrix layout must be understood first: under a common convention, columns represent observation times and diagonal entries…
The discussion asks whether a spread move reported for a bond segment can estimate the price change of a bond trading far below par when no bond-specific price history is available. It distinguishes ordinary discounted bonds from distressed debt and explains…
The document outlines possible approaches to hedging municipal bond portfolios with BMA or SIFMA-indexed swaps. For portfolios made mainly of senior variable-rate demand obligations or similar floaters, it suggests comparing the historical root-mean-square…
The document explains that derivative counterparty-risk models must specify how a defaulted transaction is valued for settlement. It distinguishes risk-free close-out, which values the contract without counterparty-related risk factors, from substitution or…
The discussion explains how the cheapest-to-deliver bond can make a Treasury futures curve trade differ from the yield spread suggested by the contract names. A 10-year Treasury note future may be priced around a deliverable bond with a maturity closer to…
The document asks whether stock prices, log returns, and cumulative returns have probability density functions, cumulative distribution functions, or both, and when each representation is useful. The included answer explains that a cumulative distribution…
The document describes a student fund’s effort to improve how it represents a domestic government bond index held through fixed-income ETFs. Its current approach treats the index as one bond, discounts projected cash flows, and feeds that estimated value…
The document explains the basic valuation framework for residential and commercial mortgage-backed securities: estimate the security’s cash flows and discount them to calculate present value. The central difficulty is forecasting those cash flows, especially…
The document addresses Monte Carlo valuation of a call option on a zero-coupon bond under the Vasicek short-rate model. It first challenges the question’s stated closed-form benchmark, deriving a bond-option price using the Vasicek bond pricing function and…
The document distinguishes what HJM and commonly used Markovian short-rate models say about interest-rate curves. HJM specifies the current forward curve and models its evolution across maturities. A short-rate model specifies the evolution of the…
The document considers the one-year forward value of an equity that pays a known dividend after six months, with different interest rates for the six-month and one-year terms. Under deterministic rates and risk-neutral valuation, the answer carries the…
The document discusses why borrowers and investors choose debt or equity to finance an investment. It emphasizes the available collateral, cash flow, uncertainty, and potential upside. A young company with little collateral and negative cash flow may…
