Bull case
The bull case prices GSK at 13x on FY1 earnings, assuming continued execution and no meaningful deceleration in the core business.
Wall Street verdict, consensus price target, and analyst rating breakdown — everything needed to frame the risk/reward at today's price.
Three scenarios for where GSK stock could go
The bull case prices GSK at 13x on FY1 earnings, assuming continued execution and no meaningful deceleration in the core business.
At 10x on FY1 earnings, the base case reflects a reasonable but not stretched valuation. It prices in continued growth without assuming an exceptional setup.
If investor confidence fades or macro conditions deteriorate, a 8x multiple contraction could push GSK down roughly 57% from where it trades now.
