The document responds to a beginner’s difficulty identifying widely traded ETF symbols by outlining how funds can be grouped into asset classes and investment styles. One answer points to a commercial fund-classification service and gives an example of how a…
The document seeks monthly market capitalization data for a set of equity, commodity, bond, and real estate indices. The intended use is to construct a value-weighted benchmark across asset classes for portfolio optimization and to estimate returns with…
The document explains why a company’s exchange listings do not directly reveal what share of its equity is owned by investors in each country. Identical or equivalent shares and depositary receipts may be fungible in value, while reported share counts may…
The document considers how to measure relationships between hedge fund returns when distributions are skewed and heavy-tailed, with particular interest in how funds behave together during market declines. It explains why Pearson correlation may be…
The document addresses how to identify a particular financial index when providers publish many strategy, currency, or other variants under similar names. Its example is a family of hedge fund indexes whose labels differ by strategy and currency, making…
The document considers how a mathematically trained researcher can find publishable questions in financial mathematics, especially beyond algorithmic trading. Its answer cautions that identifying problems with academic value and broader economic or social…
The document explains why cumulative return charts can show gaps when asset return series contain missing observations. Those gaps reflect the data and should not be hidden by chart-level interpolation, since filling values changes the underlying return…
The document is a categorized directory of online sources for finding quantitative finance research and related publications. It covers platforms that let readers search, view, or download papers; indexing services that can help locate open versions; a…
The document explains how a swap’s discounting can change when the collateral poster may choose between eligible currencies. This choice resembles a cheapest-to-deliver option: the poster prefers the collateral class with the most favorable return, and the…
The document explains how the Markowitz mean-variance framework treats portfolio returns over a chosen investment period. Its example combines stocks and bonds with equal weights and shows that the portfolio’s expected return is the weighted average of the…
The document asks whether the fundamental pricing identity for an asset divided by a numeraire remains valid when their values are correlated. The answer explains that correlation does not invalidate the identity: under the measure associated with a strictly…
The document asks whether one exchange-traded fund can provide exposure to equity markets around the world, rather than tracking a single national index. The answer points to two broad-market products: one tracking the FTSE Global All Cap Index and another…
The document considers a cross-currency basis swap and an offsetting hedge booked with different counterparties under different collateral agreements (CSAs). Because one trade is collateralized in euros and the other in dollars, a move in cross-currency…
The document addresses how to learn what market moves may imply, using higher swap rates as an example. It argues that “market situations” span too many instruments and causes for one book to explain them comprehensively. A useful starting point is to study…
The answers distinguish evaluating a long-term strategic asset allocation from measuring tactical tilts around that policy mix. Strategic allocation should be judged against the institution’s required return profile and mission; an endowment, for example,…
The document frames a model-selection question about dependence between empirical asset returns. It contrasts the Student t copula, which permits symmetric tail dependence, with the Clayton copula, which captures asymmetric tail dependence, and asks which…
The document surveys research on whether cryptocurrencies differ quantitatively from currencies and other assets. It describes proposed distinctions such as decentralized transaction records, market-specific drivers, high volatility, and limited history. The…
The document considers how to estimate a portfolio’s sensitivity to movements in one yield curve when positions also depend on correlated prices and rates. It suggests starting with assumed volatilities and correlations: shock the target factor, infer…
The document explores whether predictive models should use market closing prices or adjusted prices, which account for distributions such as dividends. The author considers a model forecasting Dow Jones returns from other indices, commodities, and…
This discussion considers how to measure a bond portfolio's sensitivity to a yield shift in one currency when the holdings are denominated in several currencies. A weighted average of bond modified durations describes sensitivity to a simultaneous parallel…
This note outlines the factors said to inform the currencies and weights in the International Monetary Fund's Special Drawing Rights basket. The answer describes the SDR primarily as a unit of account for the IMF and related institutions, rather than as a…
The note proposes a set of indicators for monitoring foreign exchange risk at different horizons. For short-term market stress, it recommends tracking implied-volatility indices across equity, bond, and FX markets, alongside funding and credit signals such…
The document compares pricing an at-the-money European call on a two-stock basket with a multivariate local volatility model using constant correlation and a Gaussian copula using the same correlation. It reports a result for models calibrated to each…
The document considers whether a currency’s returns can be regressed on an average return across currencies to estimate beta, and whether that beta has a CAPM interpretation. One reply argues that this benchmark may be unsuitable because exchange-rate…
