Chаllenge Optiоn mаrket‑mаkers (i.e., clearinghоuse members whо serve as counterparties to all contracts) prefer a business model in which they pair off positions. For example, if one trader wants to take a long position in a particular option, the market‑maker would ideally find another trader willing to take the corresponding short position in the same contract. The market‑maker then earns the bid–ask spread, while the two traders bear the underlying risk. In practice, however, demand is often highly correlated: if one trader wants a long position, many others typically want the same long position, and few are willing to take the short side. As a result, market‑makers frequently cannot offset positions and instead must synthetize the options they sell. Due to geopolitical crises, the stock prices of North American oil drillers have risen significantly. The price of Exxon stock has increased from $100 per share to its current level of $155. Today, retail traders are betting that these stocks will be “crushed” by a surprise resolution to the crises. As a result, a market‑maker has received an overwhelming number of buy (long) orders for DOOM 0DTE options, with few or no offsetting sell (short) orders. The market‑maker believes that if the price is "crushed,” it will finish the day at $115. If it isn't, it will finish the day at $160. The one‑day gross risk‑free rate is effectively zero (i.e., R = 1.00). Choose the transactions required to synthesize an option with a $135 strike price.
