The document is a request for learning resources on TIMS and SPAN, methodologies used to calculate margin. The response points out that margin is not a single uniform topic and asks the learner to distinguish between margin for centrally cleared products and…
The document discusses how to model an average-price option on Dated Brent futures. Its payoff depends on the average price of nearby futures over an averaging period, which can involve more than one futures maturity. The questioner considers applying the…
The document compares contracts for difference (CFDs) with single stock futures (SSFs). It notes that both account for interest and are settled daily, so their economics can appear similar at first glance. The central distinction is market structure: CFDs…
The document reconciles two statements about stock forwards: the no-arbitrage forward price for a non-dividend-paying stock is determined by spot and financing, while an economic pricing relation can express it using the expected future stock price and a…
The document asks why an over-the-counter option can be harder to hedge when its expiry does not align with a major listed contract’s expiry, even if both options reference the same underlying futures contract. The example contrasts an OTC gold option…
The document considers whether a reasonably sized hedge fund commonly splits a strategy across brokers to reduce the risk that one broker becomes unavailable. The accepted answer says firms often use several brokers because each serves a different…
The document explores how to define an index trend and why simple indicator crossings can give misleading signals. It contrasts a basic comparison of current and reference closes with stochastic %K/%D and MACD line/signal relationships, noting that a short…
The answer explains why weather derivatives can have many risk-neutral probability measures when the underlying temperature is not tradable. Without a tradable underlying, the contracts cannot be replicated or hedged using temperature itself, so the market…
The document asks how to give three-month SOFR futures precedence over one-month futures when bootstrapping a term curve alongside SOFR swaps. It describes a practical selection rule: inspect the existing rate helpers for a matching pillar date before adding…
The document discusses how to assess fair value estimates for non-US equity index futures before expiry, where the estimate depends on financing costs and expected dividends. It notes that closed foreign-exchange markets can complicate the interest-rate…
The note shows how to infer a market-implied probability of a Federal Reserve rate hike from a monthly fed funds futures settlement. Because the contract settles against the average effective federal funds rate across the month, its price reflects both the…
The document discusses whether futures rolls can distort short-end yield curves built from nearby interest rate futures. A roll may create short-lived imbalances that affect observed futures prices and, in turn, the rates inferred from them. The answer…
The document addresses how to calculate returns for an active interest rate futures contract when the underlying contract changes at expiry. It recommends constructing a synthetic adjusted price history, commonly by shifting older contract prices so they…
This discussion considers how a retail investor might gain exposure to a future twelve-month LIBOR fixing to hedge a liability tied to rising rates. The direct instrument identified is a forward rate agreement, but the answer says retail access and liquidity…
The document addresses why explanations of futures notional value may multiply contract size by either the futures price or the spot price. The response argues that futures contract size and notional conventions are not universal measures of comparable…
The document discusses the difficulty of finding a vendor that streams delayed order-book data, including market depth and order-by-order feeds, for selected futures contracts. The replies emphasize that exchange data rights govern redistribution: a firm…
The question concerns implied volatility for options on eurodollar and other short-term interest rate futures. The accepted response explains that these contracts are quoted as prices tied inversely to interest rates, so the futures price and strike can be…
The document surveys quantitative and systematic approaches reported to have performed well during the 2008 crisis. It identifies managed futures, especially trend following in futures markets, as a major systematic category that did well. It also discusses…
The document distinguishes futures open interest from the physical production of a commodity. Open interest counts outstanding contracts, with a long and a short side for each contract; it does not represent a quantity of grain that buyers can collectively…
The document asks how to size 10-year Treasury micro futures against a full-sized 10-year note futures contract when adjusting exposure for volatility. It reports an estimated volatility ratio of 5.125 between the micro and full-sized contracts and seeks the…
The answers explain why trade prices and volumes can appear when displayed ask quotes are absent or zero, and why a reported bid can sometimes exceed the ask. Trades may result from immediately executable orders that never rest in the visible book, while…
The document raises a practical implementation problem for a mean reversion strategy on multiple cointegrated assets. The cited model estimates an optimal inventory from regression estimates and their derivatives, but its output consists of fractional asset…
The document examines how to adjust a minimum-variance cross-hedge when futures are marked to market daily. It contrasts the hedge ratio based on correlations and standard deviations of price changes with the contract count based on position values. The…
This discussion considers how to summarize yield for a portfolio containing US government bonds and Treasury futures. One proposed approach is to compute a market-value-weighted average of the bonds’ yields to maturity. The replies distinguish the role of…
