In opting for a long call spread, the trader lowered the initial net debit on the TMUS trade -- as well as the breakeven point -- by offsetting the entry fee with the premium received from the sold contracts. In this way, the trader also lowered their maximum risk. Long call spreads are ideal plays for traders who are bullish towards an equity, but are comfortable limiting their profit potential on an upside move in exchange for the decreased cost of entry and lowered capital commitment (relative to a "vanilla" call buying strategy).
