GSK stock rebounds 5.6% as the confirmation week stays open

August 21, 2026

Our view last week

GSK breaks below its trigger level and sheds 7.3% in a week, its heaviest drop in months. The picture flips: last week GSK stock was still inside a buy signal, and now a fresh sell signal kicks in, ranking third of 47 in our European-UK ranking. Signal strength is already at 94 out of 100 - the model reads it as a decline under way at lower lows, with the push still intact. The stock still sits above its 200-week average.

This week's summary

GSK stock bounces 5.6% this week, but the technical picture doesn't back up the strength of the move: two conflicting rejection candles and contracting volumes ride along with it. The Sell signal is still in its confirmation week, with strength down to 38 out of 100 - a decline holding its direction but with no fresh push. GSK stock still sits above its 200-week average, with wide running room before the next historical resistance.
