The document traces the shift in US swap spread analysis from Libor swaps versus Treasuries to cleared SOFR swaps versus cash Treasuries. It asks whether matched-maturity asset swap spreads should be near zero if SOFR approximates general collateral funding,…
The document offers several explanations for the usual upward slope of VIX futures. The responses describe long volatility exposure as crash insurance: investors may pay a premium for protection that tends to help during equity downturns, while short sellers…
The document explains that CME margin, also called a performance bond, is tied to market risk and volatility, but says the exchange’s precise calculation formula is not publicly specified in the discussion. It points readers to SPAN as the relevant margin…
The document clarifies that basis risk arises when a futures hedge does not move exactly with the asset or exposure being hedged. It gives examples where the deliverable or referenced instrument differs from the hedger’s actual exposure: wheat from one…
The document explains how inverse VIX exchange-traded products can lose most of their value despite a comparatively modest-looking change in the VIX index over a longer chart window. Such products generally maintain short exposure to near-dated VIX futures,…
The document walks through a numerical example of a long futures position whose daily gains and losses are settled in cash. Because the position controls many units while the trader posts only an initial margin deposit, a modest percentage move in the…
The document reports examples from illiquid lean hog futures in which an opening or closing price falls outside the stated high-low range. This conflicts with the usual assumption that the high and low bound all prices recorded for a bar. The author suggests…
The document explains how letter-and-digit maturity codes can identify futures delivery months and how those dates may be used when reading a curve. The letters H, M, U, and Z correspond to March, June, September, and December, while the digit gives the…
The document examines the relationship between the one-step binomial risk-neutral probability and the claim that a futures price has expected future value equal to its current value. In the binomial setup, an up move multiplies the initial futures price by…
The document discusses defending a short out-of-the-money strangle by entering a futures position when the underlying reaches a short strike. The proposed approach aims to respond before the option reaches breakeven, but the response explains that hedging…
The document derives a call option value under a Bachelier-style arithmetic diffusion with constant interest rate and volatility. It first solves for the conditional distribution of the terminal asset price, which is normal, then discounts the expected…
The document explains the key-rate duration behavior of a Eurodollar futures contract by relating its value to a forward three-month LIBOR rate. The question concerns a down shock to the three-month spot key rate that appears to increase the corresponding…
The document explains how to derive a two-year swap yield from a sequence of Eurodollar futures rates. It says Bloomberg’s displayed Rate column is already convexity adjusted, so the calculation can use those rates as period growth inputs rather than…
The document considers how to choose between two commodity futures for hedging jet fuel when their minimum-variance hedge ratios and recommended contract counts differ. It says the objective is to reduce the variance of the combined exposure and hedge, so…
The document explains why tick size, tick value, and a contract’s stated notional do not always fit a simple tick-value-to-tick-size formula. For CME Eurodollar futures, a fixed price multiplier converts a price change into position value. The minimum tick…
The document asks how traders can exploit changes in the difference between futures prices and the underlying cash asset, including how futures roll and carry costs affect the strategy. The response suggests framing this as carry or roll trading, with…
The document investigates apparent cases where Eurex DAX index put options traded below their intrinsic value when compared with the official 17:30 DAX close. The author reports that comparing the same options with FDAX futures levels removes the…
The document discusses assigning intraday timestamps to daily commodity futures prices collected across several exchanges. Its central practical lesson is to distinguish a contract’s settlement time from the end of its trading session: those times can…
For a futures position, exposure should be measured using the contract’s own price, since changes in that price determine the position’s profit and loss and daily variation margin. The contract size multiplied by the futures price is therefore the relevant…
The document outlines the cost components used to relate an oil spot price to a theoretical futures price. It includes funding, storage, and the cost of removing oil from storage and transporting it to the delivery point. Funding is represented by the…
The document discusses whether a well-known book on Treasury bond basis remains useful for learning US Treasury bond and note futures. The respondent considers it a strong reference for the market’s history and analytical methods, despite its publication…
The document shows an attempt to reproduce a Federal Reserve rate-hike probability displayed by a futures-market calculator. It uses two monthly fed funds futures prices to infer the implied average rates for the current and following months, then solves for…
The document explains why a VIX futures contract can show a positive settlement price even when its reported volume and open interest are zero. It distinguishes a settlement price from evidence of an executed trade: an exchange can determine a daily mark…
The document sets up a short, constant-horizon forward strategy in a contangoed market and asks how rolling positions affects its value. It models exposure across adjacent maturities, imposing both a target effective maturity and a self-financing condition.…
