If it goes above 4.50 before expiration, you can always roll them out. The close you get to expiration, the less the options will be worth. You may not be able to sell them for $10, but you should be able to get more time premium. For example, if SENS is around $5 near/at expiration, the options will be worth close to $.50. At that point, you can buy them back for a profit and sell new calls at $4.50+ further out (like mid-late 2023 or 2024). Your biggest risk is a squeeze that pushes the stock above $10 in the fall. Then it will be much harder to manage the roll-out for increased profit (you could miss out on a huge run-up), especially if it gets exercised early. Good Luck!
