During the strengthening of the franc, option traders actively gained 'naked puts' levels. To create a spread strategy, traders can add a long position in the underlying asset, resulting in a breakeven call or a spread when selling an out-of-the-money call in the same series. This allows the trader to enter the market with no risk or even a small profit immediately. Based on this advantage, we expect a surge in buying activity at the current level or slightly lower.
