When I see/read that Glaxo's shares have been ranging for 20 years, I can't help but be reminded by your service's maxim that, ranges are explosions waiting to happen." After 20 years, one must wonder when and in what direction will we see the explosion?

Thank you for this topical question. Glaxo has been a highly innovative company and yet the share has been locked in a lengthy and volatile range for decades. That suggests the innovations that drove the original bull market and funded the M&A activity that created GlaxoSmithKline are priced in.
