This document raises a question about the relationship between three-month Euribor and the ECB deposit facility rate. It observes that unsecured term borrowing rates had remained below the rate banks could receive on central-bank overnight deposits, and asks…
This document frames a pricing problem for defaultable bonds when default intensity is stochastic and correlated with the risk-free interest rate. The proposed setup uses a two-factor Gaussian model, with one factor for rates and one for default intensity,…
The document examines how to interpret annual effective-rate discounting when the cash-flow horizon is a fraction of a year. It starts from the present-value relation that divides a future value by one plus the annual rate raised to the time in years. The…
The document surveys ways to obtain U.S. listed-equity short interest, distinguishing reported short interest from short-sale volume. It notes that FINRA’s short-sale volume resources do not provide the position-style interest measure sought, and that some…
The document asks how to represent two standard Wiener processes with instantaneous correlation ρ using one process and an independent Wiener process. It proposes defining the independent candidate by subtracting the correlated component of one process from…
The volatility smile records how market implied volatility varies across option strikes. The document explains that reproducing this pattern is a practical test of an option model: the smile is a widespread market feature, observed across asset classes, and…
The question asks for the conditional second moment of the time integral of Brownian motion given its values at the interval endpoints. The proposed route expands the square as a double integral of conditional products, then considers the conditional…
Potential future exposure (PFE) measures the possible future value of a derivatives position that could be lost if a counterparty defaults. The document addresses why high positive exposure is considered adverse: a profitable position means the counterparty…
The document introduces resources for finding R packages used in quantitative finance, naming the CRAN Finance task view and packages such as FinancialInstrument, RTAQ, blotter, and quantstrat. It poses practical questions about package choice, alternatives,…
The document asks whether momentum trading and positive feedback trading are distinct concepts, and whether individual trader data is needed to identify positive feedback or herding. The response treats momentum and positive feedback as conceptually…
The document asks whether steep contango in nearby VIX futures as a contract approaches expiration can serve as a useful market-timing signal. The response explains that a VIX futures price reflects the market’s pricing of expected S&P 500 realized…
The document discusses ways to obtain a spreadsheet of large companies ranked by market capitalization, with company names, countries, and comparable market values or weights. The suggestions include using holdings from a global equity ETF to approximate a…
The document discusses ways to improve finite difference methods for solving the Black-Scholes equation, with attention to accuracy, speed, and stability. Its main recommendation is to transform the equation into the heat equation, which has simpler…
The document considers why a leveraged fund might hold a cash bond to obtain interest-rate exposure when an OIS swap could provide similar sensitivity. It does not identify a universal pricing advantage when the instruments are fairly priced. Instead, the…
The document explains how to turn a one-step ARMA-GARCH point forecast and volatility estimate into a forecast interval when standardized innovations follow a skewed generalized error distribution. The conditional return is modeled as an ARMA mean plus a…
The document recommends research on how hedge fund tail risk relates to fund performance and where that risk originates. It points to a study of equity-oriented hedge funds that examines both the tail risk of stocks held by funds and the effects of funds’…
The document describes a Monte Carlo implementation of the Heston stochastic-volatility model, using an exponential stock-price step and an Andersen moment-matching update for variance. The author observes that simulated variance trends downward when…
The document asks whether mean semivariance optimization and Post-Modern Portfolio Theory (PMPT) downside risk are equivalent when they use the same benchmark. It presents semivariance as the average squared shortfall of observed returns below a threshold,…
The document reports a numerical comparison between an adjusted Kirk approximation and the Bjerksund–Stensland spread option model. The author implements both formulas, adds a weight for the second spread leg, and includes call and put calculations. Across…
The response challenges the idea that a total return swap without a formal early-termination clause should be valued by projecting its cash flows to maturity. It separates the swap into an underlying instrument leg and a financing leg. For a dealer holding…
The response argues that public exchange option volume and call-put ratios cannot reliably establish whether dealers are net buyers or sellers of single-name options. Much options activity occurs through private over-the-counter trades, which are not…
The document poses three questions about pricing an American contingent claim (ACC): how to decompose its discounted fair value, why the matching European claim should not be worth more, and when the two prices coincide. The supplied partial argument…
The discussion compares pricing approaches for forward-looking LIBOR-style caplets and backward-looking caplets based on compounded overnight rates such as SOFR. It describes using Hagan implied-volatility approximations with SABR parameters, then adjusting…
The document clarifies that risk-neutral valuation applies to European-style derivatives whose maturity payoff is measurable and integrable, whether that payoff depends only on the terminal asset price or on the path taken. With constant interest rates, the…
