Im pretty new to calls/options but hows that possible since the stock only went up like 25%. Was your strike price super low?

Super simple: Call = buy the right to buy the stock for $55 and you pay $1 for that. Stock goes from $55 to $60, the right to buy the stock for $55 is now worth $5. For everything more just read or watch some tutorials on options.
