Stephen "Sarge" Guilfoyle calls the space industry a "niche" trade that will become increasingly more important in the years to come, thanks in part to SpaceX's (SPCX) recent IPO. He likes Rocket Lab (RKLB) and explains why there's plenty of upside despite the stock's fall from all-time highs. Luke Lloyd warns that SpaceX will lead momentum short-term across the space sector. His stock picks include AST Spacemobile (ASTS), which he sees taking market share back from SpaceX.
