Dollar carry trade
A systematic foreign exchange (fx) approach—Dollar carry trade—defined by explicit rules, testable on history, and fragile when costs or regimes change.
Overview
Dollar carry trade sits in the Foreign Exchange (FX) chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
Based on the research catalog 151 Trading Strategies (Kakushadze & Serur, 2018), section 8.3. Educational summary—not a replication of the full formal definition.
How the Strategy Works
Dollar carry trade in Foreign Exchange (FX) is defined by explicit positions and transition rules—translate each clause into code or a checklist. The catalog frames it this way: This strategy is based on the average cross-sectional forward discount D(t,T ) (see, e. Your implementation must preserve that economic intent while making every parameter explicit.
The published definition of Dollar carry trade (catalog §8.3) specifies when exposure changes; discretionary overrides invalidate systematic claims.
Implementation and Research Process
Decompose Dollar carry trade into signal, portfolio construction, and execution modules—each must be path-independent given the same historical tape.
Document Dollar carry trade capacity in Foreign Exchange (FX): intended participation versus average daily volume.
Archive Dollar carry trade failure modes with dates—research firms learn from documented breaks, not from erased losing months.
Risk: What Breaks This Strategy
Carry in Dollar carry trade earns slowly and loses quickly when the funding leg inverts or the spread blows out.
Crowded carry unwinds synchronously—liquidity disappears on the exit side first.
Leverage turns a stable historical carry series into a margin-call candidate in one week.
Common Mistakes to Avoid
- Using academic §8.3 definitions for Dollar carry trade while ignoring borrow, margin, or contract specs.
- Erasing losing Dollar carry trade months instead of documenting regime breaks—that is how research firms stop learning.
- Stacking Dollar carry trade with correlated sidebar strategies without netting exposures.
- Confusing this educational Dollar carry trade summary with compliance-approved investment advice.
How to Study This Strategy
- List every data field Dollar carry trade needs in Foreign Exchange (FX); verify point-in-time integrity.
