The document discusses why newly listed CBOE Bitcoin futures traded at a premium to a cash Bitcoin reference price, despite the author's expectation that an upcoming hard fork might push futures to a discount. The response attributes the premium partly to…
The document explains why an ICE electricity futures settlement can change even when a contract records no volume or open interest. Under the described procedure, the exchange first selects an anchor expiry, identified for the products discussed as the…
The document outlines how to infer a short-term rate curve, and potentially policy-rate expectations, from forward rate agreement quotes when meeting dates do not line up with FRA accrual periods. It recommends constructing a discount curve with nodes at…
The document asks whether a single-commodity exchange-traded commodity product can accurately be described as a delta-one investment when it holds futures contracts. As a contract approaches expiry, the product must roll its exposure into a later contract.…
The document explains how a volatility forecast can inform trades in volatility-sensitive instruments. A trader who expects realized volatility to exceed the market’s expectation may buy options; a trader expecting it to be lower may sell options. It also…
The document addresses whether a trader can access S&P 500 Variance Futures on the CBOE Futures Exchange and explains why choosing a broker may not solve the problem. Its central point is that the contract was described as inactive, with little or no trading…
The document explains how to interpret principal components when their signs are mathematically arbitrary. It uses futures term-structure analysis as context, where components are often described as level, slope, and curvature. Since either an eigenvector or…
The discussion considers how to test a next-day wheat futures direction model with limited capital after encouraging backtests. One suggestion is to use a broker’s demo account to observe how the strategy behaves in live market conditions before committing…
The document clarifies what happens when an investor takes a long position in euro futures, correcting the idea that the trade involves borrowing euros and exchanging them for dollars. For a futures contract, the trader generally does not receive the full…
The discussion considers trading differences between volatility implied by SPX options and volatility reflected in VIX futures. One response describes liquidity providers hedging VIX futures or options with SPX straddles, adjusting those hedges several times…
The document discusses when futures gains and losses affect a margin account after a position is closed during the trading day. It distinguishes the executed trade prices, which determine the trader’s realized profit or loss, from hourly market quotes, which…
The document discusses two related but distinct portfolio goals: minimizing portfolio variance through asset weights, and selecting a fixed number of futures contracts whose return streams are less redundant. For minimum variance, it recommends estimating a…
The document discusses a futures and bond arbitrage explanation involving two prices, an initial cash difference, and its value at a later time. The answer describes shorting the more expensive side and using the proceeds to buy the cheaper side. It then…
The document distinguishes two meanings of open, high, low, and close data. In a market with opening and closing auctions, the open and close can be the auction prices, while the high and low are extrema across auction and continuous trading. In a second…
The document explains why practitioners may use two yield factors, typically level and slope, when analyzing bond futures and deciding which deliverable bond is cheapest to deliver (CTD). A model with more factors could represent more yield-curve movements,…
The document addresses whether a minimum variance hedge ratio requires spot and futures prices to use the same physical units. Its example compares spot prices quoted in dollars per barrel with futures prices quoted in dollars per million British thermal…
The note discusses how to set the time unit when estimating geometric Brownian motion drift and volatility from daily prices. It defines returns as successive log price changes and scales their sample standard deviation by the square root of the time step.…
The document explains how to obtain forward rates when Bloomberg displays LIBOR swap-curve information. It distinguishes forward-starting swaps from spot swaps and points to Bloomberg’s forward-analysis functions for swap rates, while separate functions are…
The document concerns proposed VIX futures strategies that use moving-average crossovers, term structure, or comparisons of historical and implied volatility to generate long, flat, or short signals. The author reports that a persistent short bias and daily…
The note compares hedging an index option with index futures against hedging with the tradable underlying. It identifies the main risk differences as basis exposure between futures and the index, the need to roll expiring futures, differences in liquidity…
The document considers how to represent margin and capital use when backtesting a long-short futures strategy. Its central guidance is that exchange margin is a minimum collateral requirement for protecting the exchange, not a sensible target for sizing…
The document asks whether futures on the same bond or equity index have different risk profiles when they mature on different dates. The answer says maturity effects depend on the underlying and the length of the available futures curve. For equity index and…
The document clarifies how to interpret the tick specification for the Mini Nikkei futures contract traded on the Osaka exchange. The quoted increment is five index points, and the stated value of one tick is 500 yen. Thus, the monetary value applies to the…
The document examines how to interpret a swap zero rate when comparing it with rates implied by a strip of short-term interest-rate futures. It cites a textbook example that compounds four quarterly futures-implied forward rates into a cumulative rate, then…
