The document asks whether the standard covariance-matrix formula for portfolio variance remains valid when some portfolio weights are negative, as they are for short positions. It presents a futures portfolio with both positive and negative contract…
Commodity Asian swaps settle against an average reference price over an averaging period rather than a single final observation. The discussion describes a typical payoff as the period’s notional multiplied by the difference between a fixed strike and the…
The document examines Hull’s two formulations for choosing a minimum-variance futures hedge. One uses the correlation and standard deviations of absolute spot and futures price changes, then scales the hedge ratio by the quantities of the asset and futures…
The document explains why buying a bond and shorting a futures contract can be viewed as a synthetic reverse repo. In a reverse repo, an asset is sold with an agreement to repurchase it later; the price difference represents financing interest, while the…
The document examines why sponsors may not issue an exchange-traded note alongside an inverse version. It explains that daily leveraged and inverse notes are path-dependent: their exposure resets as their values change, so the pair’s gains and losses do not…
The document raises a question about the payoff represented by Black’s model for an option on a futures contract. It distinguishes the futures price agreed when the option is exercised from the later spot price at the futures contract’s own maturity. The…
The discussion separates a futures contract’s initial market value from its price, economic exposure, and the obligations created by taking a position. At a market transaction price, the contract typically starts with zero market value, while the long still…
This exchange concerns transforming the Black–Scholes equation from an underlying spot price to a forward or futures price to obtain an equation for options on futures. The question gives the relationship between spot and forward prices and presents the…
The document asks how to profit if one asset earns a higher return than another over a fixed period, regardless of whether either asset rises or falls. The answers identify a pair trade as a direct way to express that view: go long the expected outperformer…
The document describes a forecasting setup for daily commodity prices using an LSTM network and predictor variables drawn from current and lagged observations. The author asks whether forecast accuracy can determine if the model is suitable for managing…
The document asks how futures positions can change a portfolio’s beta, referring to a textbook explanation that reduces beta by cutting short futures contracts and raises it by adding long contracts. The underlying idea is that a futures position contributes…
The document explains two labels that may appear on otherwise similar futures listings: “full” and “only.” The answer interprets them as references to trading sessions. “Full” denotes the broader CME Globex session, while “only” refers to the open-outcry…
The note explains why the Nifty 50 level observed at 3:30 pm may differ from the price used to settle index options on expiry. The answer states that the settlement price is based on a weighted average of prices during the final 30 minutes of the expiry day.…
The document asks how to value a tracker certificate linked to a basket of index futures. It compares this with a proposed approach for an equity-index tracker: project the underlying using a forward curve, then discount using a discount curve. The question…
The discussion compares ways to hold a long-term view on oil: physical storage, futures, oil-company shares, and other instruments. Physical oil requires storage infrastructure, while rolling futures can incur costs or benefit from the shape of the forward…
The discussion explains that an issuer can create a contract whose payoff tracks an asset such as gold by promising clients a cash settlement tied to a defined reference price. This is primarily a contractual arrangement. An exchange traded fund, product, or…
The discussion addresses conflicting published tick sizes for Nikkei 225 mini futures. One third-party futures profile lists a ten-point increment, while the exchange’s product page states a five-yen tick worth ¥500 per contract. The accepted answer says the…
The document raises two modeling issues when applying stochastic quanto pricing formulas to crypto futures and perpetual swaps. First, it questions what domestic discount rate to use when the contract is settled in bitcoin, given the absence of a…
The note surveys several forms of arbitrage and relative-value trading rather than developing one strategy in depth. Examples include capital-structure and convertible-bond trades, merger and latency arbitrage, ETF and index arbitrage, and relative-value…
The note explains how to estimate fair value for a futures contract using the cost-of-carry relationship. For an index future, it relates the spot index level to financing over the contract term, adjusted for income such as dividends. The same idea can be…
The discussion explains a common source of discontinuities when building return series for standardized contracts such as IMM swaps or credit default swaps. A fixed-maturity CDS quote can remain stable across a roll date, while its label as an on-the-run…
The document discusses how to size the legs of a steepening yield-curve trade using Treasury futures. It clarifies that futures prices are market quotes; the practical sizing question is how many contracts to hold on each side. One common approach is DV01…
The document explains why a futures contract’s implied repo rate may be higher when the short delivers on the last eligible date rather than the first. The key detail is that the invoice price includes accrued interest in addition to the futures price…
The document examines whether a short run of profitable manual trades in equity-index futures can support expectations of unusually high annual returns. The responses caution that a small number of recent trades is weak evidence for persistent skill, and…
