Hedging for currency options
ОглавлениеThe currency option market is a massive counterpart to the spot market and can heavily influence day-to-day spot trading. Currency option traders are typically trading a portfolio of option positions. To maximize their returns, options traders regularly engage in delta hedging and gamma trading. Without getting into a major options discussion here (we cover currency call and put options in Chapter 15), option portfolios generate a synthetic, or hypothetical, spot position based on spot price movements.
To maximize the return on their options portfolios, they regularly trade the synthetic spot position as though it were a real spot position. Trading the synthetic positions generated by options is called delta hedging or gamma trading.
Option hedgers are frequently found selling at technical resistance levels or buying on support levels. When a currency pair stays in a range, it can do quite nicely. But when range breakouts occur, options traders frequently need to rush to cover those range bets, adding to the force of the directional breakout. Keep an eye out for reports of option-related buying and selling as technical levels are tested. (See Chapter 6 for more about technical analysis.)
Another daily feature of the spot market is the 10 a.m. ET option expiry, when options due to expire that day that finish out of the money cease to exist. Any related hedging that was done for the option then needs to be unwound, though this is likely to have been done prior to the expiry if the option is well out of the money. Traders need to follow market commentaries to see whether large option interest is set to expire on any given day and generally anticipate a flurry of option-related buying/selling that may suddenly reverse course after the 10 a.m. expiry.
