When Theory Meets the Market – Part 2: The Danger of Looking at a Trade in Isolation

Financial transactions are not always what they appear to be when examined individually. A purchase of shares may form part of a hedging strategy, an FX transaction may offset an existing currency exposure and a derivative position which appears speculative may be one component of a wider commercial arrangement.

In financial litigation, considerable attention is sometimes directed towards individual trades which when considered on their own appear unusual, commercially irrational or inconsistent with their stated purpose. However, before reaching such conclusions, it is important to establish whether the trade was intended to operate independently or formed part of a broader strategy.

This distinction can materially affect the interpretation of both the trading activity and its economic consequences.

 

Understanding the Complete Transaction

Many financial market strategies involve several transactions which are economically connected but legally separate. Each may have its own confirmation, settlement obligations, cash flows and accounting treatment. Examining only one component can therefore provide a misleading impression of the overall arrangement.

Consider an investor who purchases shares while simultaneously selling futures contracts over the same underlying security. Viewed independently, the purchase represents a long equity position exposed to movements in the share price, while the futures sale represents a short position which would ordinarily benefit from a fall in that price.

Taken together, however, the positions may substantially offset one another’s exposure to movements in the underlying security. The economic purpose of the combined strategy may instead relate to differences between cash and futures prices, financing costs, expected dividends or other factors affecting their relative valuation.

An analysis which treats the share purchase as a directional investment, without considering the corresponding futures position, would therefore misunderstand the nature of the strategy.

The same principle applies to FX swaps, options, securities lending arrangements and total return swaps. The relevant economic exposure may only become apparent once the different components are considered together.

 

Commercial Purpose Goes Beyond Market Direction

A common misconception is that the economic rationale for a financial transaction must be found in an expectation that the price of an asset will rise or fall. In practice, financial markets accommodate a much wider range of commercial objectives.

Transactions may be undertaken to obtain financing, manage liquidity, transfer risk, address settlement requirements or exploit differences in the relative pricing of related instruments. In some circumstances, the commercial opportunity arises not from a directional market view but from differences in the economic position of the counterparties.

Securities lending provides a useful example. A securities borrower may require shares to facilitate a short sale, hedge an exposure or meet a settlement obligation. The lender may be willing to provide those shares in return for an agreed lending fee and other contractual terms. Where a dividend is expected during the loan, the arrangements will generally need to address the economic entitlement associated with that dividend, including any manufactured dividend payment.

The terms agreed may reflect the different tax, funding and operational circumstances of the parties. Consequently, there is not necessarily a single economic value which applies equally to every participant. Differences in those circumstances can create legitimate trading or arbitrage opportunities.

Viewed in isolation, one component of such an arrangement may appear to have been priced unusually or to offer little commercial benefit. However, the rationale may become apparent when the securities lending terms, financing arrangements and related derivatives positions are considered together.

The existence of a possible commercial explanation does not establish that every transaction was genuine or economically justified. It does mean that the explanation should be tested against the complete arrangement rather than dismissed because an individual component appears unusual.

 

Economic Exposure and Profitability

Another difficulty arises when the size of a transaction is confused with the risk it creates.

An FX forward involving a substantial notional amount may appear speculative when viewed independently. However, if it offsets an existing currency liability, the transaction may reduce rather than increase the holder’s exposure to exchange rate movements.

Similarly, an FX swap involves two related currency exchanges at different value dates. Considering only one leg can suggest a substantial directional currency position, whereas the combined transaction may leave the participant principally exposed to the pricing of the swap, including the relevant interest rate differential.

The same problem can arise when assessing profitability. A transaction may generate a loss when considered separately while contributing positively to the economics of the overall strategy. A hedging cost, financing expense or payment associated with a securities lending arrangement may be an integral part of generating a return elsewhere.

This becomes particularly important where related transactions are recorded in different accounts, undertaken with different counterparties or settled during different reporting periods. Unless the associated cash flows and positions are reconciled, the overall economic outcome may be misunderstood.

The relevant question is therefore not always whether an individual trade made money, but whether the complete arrangement achieved, or was reasonably capable of achieving, its intended commercial purpose.

 

The Importance of Timing

Even where economically related transactions have been identified, their timing may affect the analysis.

A hedge may be established after the underlying position, adjusted as market conditions change or replaced as contracts approach maturity. Similarly, an arbitrage strategy may involve transactions entered into at different times as financing, securities borrowing or pricing opportunities become available.

Options strategies illustrate this particularly well. A position may initially have a particular risk profile, but movements in the underlying market can alter its delta, gamma, volatility exposure and margin requirements. Subsequent transactions may therefore be intended to manage existing exposures rather than establish new speculative positions.

Examining those adjustments individually can give a misleading impression of the trader’s intentions and the risks being undertaken.

However, identifying a relationship between transactions does not automatically mean that the resulting strategy was prudent or commercially successful. The effectiveness of the strategy, the risks retained and the circumstances prevailing when decisions were made still require examination.

 

Looking at the Whole Picture

In complex financial disputes, there is often a temptation to concentrate on the transaction which appears most unusual or which produces the largest reported profit or loss. That may be a useful starting point, but it is rarely sufficient where the transaction forms part of a wider arrangement.

A proper analysis may require the reconstruction of positions across several instruments, accounts, counterparties and periods, together with the reconciliation of trading activity, financing costs, settlement records and P&L.

The wider analysis may ultimately support the allegation being advanced. It may reveal that the purported commercial rationale is inconsistent with the transactions, that an apparent hedge was ineffective or that substantial risks remained despite offsetting positions.

Equally, it may demonstrate that transactions which initially appeared speculative, artificial or commercially irrational were components of a coherent financial strategy.

The important point is that neither conclusion should be reached before the relationships between the transactions have been properly examined.

A trade may be straightforward to identify, but its economic purpose can only be understood in the context in which it was undertaken.

 

In Part 3 of When Theory Meets the Market, I will examine the dangers of hindsight and why financial decisions should be assessed against the information and market conditions prevailing at the time, rather than by reference to what subsequently happened.
