How do I hedge stock options like market makers do?
Let's consider that transaction cost is 0(zero) for calculation. In the scenario you have stated, maximum profit that could be made is 55$, however risk is unlimited. Hedging can also be used to limit your losses, let's consider this scenario. Stock ABC trading @ 100$, I'll buy the stock ABC @ 100$ and buy a put option of ABC @ strike price 90$ for a premium of 5$ with an expiration date of 1 month. Possible outcomes I end up in a loss in 3 out of 4 scenarios, however my loss is limited to 15$, whereas profit is unlimited.
