The document explains how to adjust a short options position when its aggregate delta moves from neutral to positive. To bring delta back toward zero, the answer recommends selling the underlying, such as its futures contract. The position’s reported Greeks…
The discussion explains the Eurodollar Synthetic Forward Curve as a futures-implied curve that can serve as a reference for short-maturity bond analysis. It is built from Eurodollar futures prices, which imply forward rates. In the cited ABS convention,…
The discussion considers whether two principal components can recover theoretical prices for futures contracts when the components were computed from cumulative log differences. It explains that reconstruction depends on how much of the original variation…
The document outlines two broad ways to gain leveraged exposure to an underlying security. Loan based approaches use the purchased asset as collateral, as with a broker margin loan; bond traders also use repo financing. These methods involve borrowing…
The document discusses comparing long basis positions in Treasury futures, using the TU and FV contracts as examples. The questioner considers ignoring option value, compares quoted cheapness in basis points, and asks whether expected profit on a fixed…
The document explains why rolling a futures position is associated with a price difference even though the expiring contract’s profit or loss has already been realized. It distinguishes an immediate cash payment from the economic effect of moving exposure to…
The document addresses why an S&P E-mini futures opening price may differ substantially from the prior reported close. Its central point is that “open” and “close” are defined prices whose calculation depends on the security and exchange rules. An opening…
The discussion considers whether broker choice and market access can reduce latency and slippage for a futures trader using frequent round trips. Answers describe services available at the time, including direct market access, configurable order routing,…
Futures do not always require delivery of a physical asset. Contracts referencing rates, volatility measures, commodity indices, or equity indices can settle in cash: the parties exchange an amount based on the contract’s final value rather than transferring…
The document raises a notation question about put–call parity: why one presentation gives the call-minus-put difference as a futures price, while another expresses it as a discounted difference between the forward price and strike. It asks whether this…
This note explains how the sensitivity of a three-month SOFR rate to an overnight-rate change after an FOMC meeting can be estimated. It compares the days in the post-meeting portion of the contract period with the full contract period. That fraction gives a…
The document considers an investor who borrows euros to buy US stocks and wants to offset the resulting EUR/USD exposure with currency futures. It explains why matching the initial euro borrowing amount may not maintain a precise hedge: the value of the…
The document considers how to remove seasonal patterns from agricultural futures data. Its answer cautions that seasonality can vary by commodity: planting, growing, and harvest schedules, including the number of harvests, may shape within-year patterns. It…
The document asks how to model energy forward curves using a seasonal component plus a smooth deviation, and whether alternatives exist to the Lucia–Schwartz seasonality specification. It names the Gabillon two-factor model as one alternative, describing it…
The discussion clarifies that the start and end periods in a CME futures margin table refer to ranges of contract expiration dates. They do not indicate calendar windows during which every contract receives the listed margin, nor do they simply assign a…
The document derives a spot-price stochastic differential equation from a model for futures prices whose volatility decays with time to maturity. Setting the spot equal to the futures price at maturity, it first rewrites the log spot using the initial…
The document explains why a cumulative return comparison between IEF, a Treasury ETF, and front-month 10-year Treasury futures can be misleading. A continuous series of front-month futures prices may show a price gap when contracts are rolled, even though…
The document asks how to align volume bars from different futures so their returns can be used in multivariate analysis. It notes that each contract reaches a fixed traded-volume threshold at different times, making timestamps inconsistent, and cites volume…
The discussion examines an apparent futures cash-and-carry opportunity when a Treasury futures contract’s implied repo rate exceeds the actual financing rate. It explains that the spread is not necessarily risk-free: the trade uses balance sheet and…
The discussion addresses whether buying a Eurodollar futures contract produces a gain when its quoted price is unchanged from entry through expiration. Its central point is that a buyer who enters at 99.80 and settles at 99.80 has no price-based profit or…
The document explains why currencies and futures can be treated as assets with known yields. The key idea is that an investor can combine a spot position with an offsetting forward or futures position, setting the future sale price in advance. For a currency…
The document asks why short-term repo implied by Euro Stoxx 50 options can be materially higher than repo implied by options on constituent shares, and whether index financing should match an average of single-stock financing. The response emphasizes that…
The document asks for a derivation of the convexity adjustment between forward rate agreements and futures rates under the Ho–Lee short-rate model. It specifies that the short rate evolves with a time-dependent drift and constant volatility, and states a…
The document points readers interested in yield curve spread trading with Treasury futures toward CME Group educational pamphlets on inter-commodity interest rate spreads and yield curve spread trades. It names the topic through examples such as NOL, NOB,…
