The document presents a question about applying the Johansen procedure to oil and corn price series after unit-root tests suggest both are nonstationary. It shows example eigenvalue and trace test statistics alongside critical values, then asks how to…
The document distinguishes a futures contract’s price from its value. At initiation, the contract is entered without an upfront payment between the parties, so its value is zero even though its agreed futures price is not. As the market price moves, the…
A student preparing for an exam asks which quantitative risk management topics to review and seeks an accessible online book. The accepted response recommends a book on integrated energy risk management, noting that it introduces core risk concepts in the…
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 considers how to price European calls and puts on an underlying that can jump, fluctuates with short-term supply and demand, and tends to lose value over longer horizons. It also raises practical questions about physical delivery and indivisible…
The document considers whether publishing a technical indicator can reduce its subsequent trading performance. It frames a strategy’s historical results as a mix of genuine alpha and overfitting, with only genuine alpha expected to persist out of sample;…
The document explains how volatility inputs differ when an option expires before its underlying commodity forward settles. It distinguishes options on different forward contracts: a quote for a two-month option on a two-month contract should not…
The document discusses how to reduce the risk of trading spurious cointegration by screening candidate assets for economic relationships. It recommends looking for securities with strong ties, such as related commodity benchmarks, a commodity and associated…
The document addresses how to obtain prices for a specific futures contract rather than a continuous series. It uses a wheat contract identified by exchange, delivery month, and year as an example, and asks whether Quandl provides this contract-level data or…
The note gives a brief overview of venues and access considerations for power derivatives. Responses mention ICE and NYMEX for over-the-counter power contracts, CME as another derivatives venue for power markets, and Clearport settlements as a place where…
The document asks how to value commodity futures options when an investor has a specific view about the future return distribution: a substantial oil price spike is considered possible over a stated horizon, with the move expected to be brief. The goal is to…
For a European option on the December Brent futures contract that expires earlier, the relevant volatility describes the distribution of that same December contract at the option’s expiry. Under the Black model for futures options, the payoff is determined…
The document explains cash-settled futures convergence through arbitrage and the contract’s settlement mechanism. In a frictionless example, an investor buys the underlying while shorting a futures contract priced above it. At expiry, the futures cash…
The document describes a problem in constructing monthly price or cost histories for groups of materials whose membership changes over time. Across roughly 200 groups, each containing from a handful to several thousand materials, purchases are intermittent…
The document asks why model-free implied volatility measures such as VIX are offered for major equity indices and only a small number of individual stocks. The accepted response adds that similar indices also exist for gold, silver, and oil, showing that the…
The document describes a proposed method for turning expiring corn futures contracts into a continuous price or return series. It tracks the nearby and first-deferred contracts and suggests switching between them when open interest in the deferred contract…
The document describes a pricing problem involving a multi-asset collar on European natural gas and US oil products, with an additional currency conversion because the contracts are denominated in different currencies. The questioner is considering Monte…
The document asks whether a closed-form barrier-option model for a dividend-paying stock can be adapted to FX and commodity futures. Under Black–Scholes assumptions, it describes forward dynamics with zero drift, so the spot-model input can be repurposed by…
The document concerns how to compress a portfolio of long and short commodity forward or futures positions across delivery months into a single front-month-equivalent exposure. The goal is to approximate portfolio profit and loss using that exposure and the…
The document asks where to obtain inexpensive historical tick data for a futures contract, using NYMEX WTI crude as an example. Its answer explains that data price often reflects whether the feed preserves all reported activity or filters some events. A…
The document explains why futures are commonly quoted by their settlement or delivery price rather than by the contract’s present value. It places this convention alongside other market practices, such as quoting bonds by yield and options by implied…
An airline expects to buy jet fuel later and uses heating oil futures to reduce the risk that fuel prices rise before the purchase. Because the airline is exposed to higher costs if jet fuel rises, it takes a long position in the positively correlated…
The document explains that exchange options, whose payoff exchanges one asset for another, do appear in practice, though listed markets are limited and often less liquid than single-asset options. In commodity futures, a zero-strike spread option can have…
