The document considers an equal-weighted composite of regional equity indexes that have different market holidays. It asks how to handle dates when one region has no observation, noting that simply removing the unavailable index and recalculating the weights…
The document explains a workflow for retrieving historical daily closing levels for total-return and other indices through Bloomberg's Excel tools. The user seeks daily observations for several regional equity and bond benchmarks that ETFs track, having…
The document considers doubling exposure to a diversified permanent-portfolio variant holding equities, long-term government bonds, gold, and real estate. Its proposed construction uses deep in-the-money call options intended to have deltas near one, with…
The document concerns possible extensions to an undergraduate study of firm-level contagion during a financial crisis. The proposed baseline is to measure company performance, such as stock returns, and explain cross-sectional differences using firm…
The document considers daily price series for assets traded in markets with different opening and closing times. Such noncontemporaneous observations can create lagged cross-correlations—for example, one market's current return may align with another…
The document describes unusually high one-year government bond yields relative to nearby maturities in Switzerland and Denmark, based on rates observed in 2012. The curve points are presented as traded yields rather than rates synthetically compounded from…
The document derives the correlation between one asset and a portfolio formed from two other assets. It defines the portfolio as a weighted combination of the two holdings, then applies covariance linearity to express the portfolio’s covariance with the…
The question concerns historical rate data needed to estimate volatility in a model using instantaneous forward rates at different observation dates and relative maturities. The response says the referenced chart already reports instantaneous forward rates…
The document explains how the price of the same product in different countries can be used to form a purchasing-power-parity comparison. The suggested procedure is to infer an exchange rate from the product prices, then compare that implied rate with the…
The document outlines a tactical allocation process for a fully invested portfolio spanning domestic and international equities, domestic fixed income, and foreign currencies. Managers express relative views on a discrete scale, including an equity…
This exchange recommends The Rise of Carry to readers seeking an account of how markets and economies changed over roughly two decades, including central-bank policy, quantitative easing, low yields, and stimulus. The recommendation frames the book as a…
The document addresses how to extend a single-asset Heston quadratic-exponential simulation to multiple correlated assets. Its central step is to generate independent standard normal draws at each time step, then transform them using a matrix square root of…
The document discusses selecting historical index data for testing portfolio optimization methods and benchmarking a 60/40 equity and fixed-income allocation. It emphasizes that the appropriate series depends on the portfolio the simulation is meant to…
The document considers how to include single-name emerging-market corporate bonds in a multi-asset portfolio when their histories are short, missing, or unreliable and trading is illiquid. Because these holdings make up a material share of the portfolio,…
The document points researchers to regulatory filings for comparing the derivatives books of large US banks. It identifies the National Information Center as a source of downloadable institution data and highlights Form FR Y-9C, which reports gross notional…
The document surveys reported portfolio construction approaches at several robo-advisors and asks whether firms rely only on Modern Portfolio Theory or use other methods. The cited descriptions include Black-Litterman expected returns, asset-weight…
The document explains why a two-asset portfolio’s usual return versus standard-deviation curve depends on asset means, variances, and covariance. With those quantities fixed, Pearson correlation determines the covariance term, so additional nonlinear…
The document describes how to generate paired observations with specified marginal distributions and dependence structure. Given a bivariate copula, it forms a conditional distribution by differentiating the copula with respect to its first argument.…
The document considers clustering methods such as k-means and k-medoids in quantitative finance. Its concrete proposed use is to identify market regimes in which relationships between assets may differ. For example, a strategy based on gold hedging equity…
The document decodes abbreviations in a national statistics trade series label. BOP refers to balance of payments, WW to worldwide, and SA to seasonally adjusted. It explains that CP means current prices: values are reported at the prices prevailing in the…
The document explains how a derivative’s discount curve can depend on which eligible collateral currency is cheapest for the posting party to deliver. Collateral earns its currency’s overnight rate; translating that rate into the derivative currency using…
The document asks why the Markit and ISM manufacturing purchasing managers’ indexes can report different monthly readings despite both serving as indicators of manufacturing conditions. The response characterizes them as similar economic barometers that use…
The document raises a derivation question for an option that pays the positive difference between two assets at maturity. Starting from the risk-neutral discounted payoff, it splits the payoff into two asset-weighted indicator terms and applies a change of…
The note explains how a foreign investor can calculate an equity return in their home currency by combining the asset’s local-currency price change with the currency’s exchange-rate change. For an investor measuring returns in US dollars, first express each…
