The document considers a calendar spread option on nearby and deferred Brent contracts, where the spread may be zero or negative. This makes a standard Black–Scholes treatment unsuitable, since its lognormal price assumption does not accommodate negative…
The document considers how a hypothetical cryptocurrency linked to a currency and a quantity of wheat might be priced, and whether market supply and demand alone would determine its value. Its answer focuses on legal redemption rights: if each token gives…
The document describes a forecasting problem for electricity futures, where delivery spans a period rather than occurring on a single date. It explains that the usual spot-and-carry pricing relationship does not capture the observed risk premium, which is…
The document explains how the usefulness of a negative option strike depends on whether the underlying can itself take negative values. For a nonnegative asset, a negative strike makes a call certain to finish in the money and a put worthless, so such…
The document distinguishes agricultural futures trading from options trading and explains why farmers may still rely on exchange prices even when they do not trade listed contracts. It says farmers typically use futures to hedge crop prices, while the…
The document explains why a persistent positive basis, defined as spot price minus futures price, can make a long futures hedge profitable on average under a particular assumption. If spot behaves like a martingale and futures begin below spot, convergence…
The document considers modeling two assets with asymmetric, heavy-tailed returns and correlated volatility shocks for value-at-risk simulation. It examines two proposed ways to couple inverse-gamma volatility shocks: quantile-transformed variables and a…
The document explains that physical electricity derivatives specify delivery over a defined period and at a stated capacity, rather than delivering a lump of energy at one instant. A capacity contract therefore corresponds to energy supplied across the hours…
The document compiles user reports about EODData’s historical and intraday market data, including equities, indices, foreign exchange, commodities, and options. Reported problems include missing records, stale files, price spikes and scale errors, absent…
The document addresses how to summarize commodity futures volumes by commodity and tenor, with purchases positive and sales negative. The suggested workflow first converts each trade’s volume into a signed quantity using its buy or sell direction. It then…
The document examines how to convert a continuous-time mean-reverting model for a commodity price into a discrete-time equation for log price. It applies Itô's lemma to the log price and an integrating factor to solve the resulting linear stochastic…
The document discusses a one-year gold forward example with a spot price, a risk-free rate, and a gold lease rate. A dealer can borrow an ounce, sell it at spot, invest the proceeds, and account for the lease cost; this gives a no-arbitrage reference for the…
The document discusses estimating downstream commodity prices, such as flour from wheat, when direct price series are unavailable. A conversion factor from raw material to finished product is not enough to capture the finished price. One response describes…
The document gathers reading suggestions for learning about commodity markets, with an emphasis on electricity. The original question seeks resources on energy products, pricing, links to quantitative strategies, and research on forecasting power prices. The…
The discussion examines why weather and insurance derivatives may be valued using historical, real-world outcomes. Their underlying variables, such as temperature or wind, are generally not tradable assets, so the standard no-arbitrage replication argument…
The note asks whether Bitcoin and Ether should be modeled as currencies with zero interest when they pay no dividends, and whether crypto carry costs instead reflect commodity-like features. Its answer compares two modeling frameworks for a stochastic…
The document examines how exchange-traded products are classified and whether ETFs, ETNs, and ETCs should be named separately in portfolio descriptions. It notes that ETF structures can include open-end funds, unit investment trusts, grantor trusts, notes,…
This exchange considers how to represent transaction costs when a futures calendar spread can be traded as a single exchange-listed contract. The question observes that the spread contract may have a lower execution cost than trading its outright legs…
The document explains why the premium difference between two calls in a spread can change after the position is opened. Its example describes an at-the-money short call paired with an out-of-the-money long call on gold, and clarifies that this leg…
The document raises a portfolio risk question: how to use principal component analysis when positions depend on more than one correlated time series, such as UK and euro yield curves or several commodities. PCA on a single curve can summarize its major…
The document explains why exchange-traded commodity futures are commonly quoted by contract expiry month, while swaps and other over-the-counter fixed-income products are often quoted by tenor. Futures exchanges concentrate trading in a limited set of…
The discussion outlines a historical Value at Risk approach for a portfolio of futures and options. It proposes applying past instrument returns to current positions to estimate historical dollar profit and loss, then selecting a lower-tail percentile as the…
The document asks how to model electricity prices, which can feature strong seasonal patterns, jumps, and negative values that make a basic geometric Brownian motion unsuitable for some purposes. The response stresses that model choice depends on the…
The document considers whether a fixed-for-floating electricity swap should be valued from the difference between the monthly futures price and the fixed contract price, or by applying Black-76 with the fixed price as a strike. It raises two conceptual…
