Why Take This Trade? Potential for a 113% Return if MU Closes Above $155
For roughly $590,000, the buyer can capture a maximum payoff of about $670,000 if MU closes above $155 by expiration. That’s a potential 113% return on risk, assuming the bullish thesis plays out. Given that MU needs just a $3.46 (or ~2.3%) move higher from current prices to max out the trade, it’s a measured bet that the current bullish momentum will persist another week.
