Lockheed Martin (NYSE: LMT) closed a recent session at $586.29, against an average Wall Street price target of $628.21, implying roughly 7% upside from current levels. One analyst, however, is far more bullish, setting a target of $756 on the defense giant while the broader consensus remains cautious. Despite that backdrop, the stock has gone essentially nowhere over the past six months, even as the company’s order backlog exploded to a record high. Among peer defense primes, RTX Corporation (NYSE: RTX) trades at $216.65 against a $229.82 consensus target, representing roughly 6% upside, with shares up 10.94% over six months and 19.01% year to date. General Dynamics (NYSE: GD) sits at $382.43 against a $414.17 consensus target for about 8% upside, with shares up 15.09% year to date.
