Qualcomm shares jump 7.1%, biggest gain since Aug 4

The sharp single-day jump signals a notable shift in market sentiment toward Qualcomm, likely driven by a convergence of earnings reception and broader tech momentum. That it outpaced the Nasdaq suggests company-specific factors are at play, not just sector-wide tailwinds. The key question is whether this reflects a durable re-rating or a short-term catch-up trade. Watching whether volume and follow-through sustain in coming sessions will clarify if the move has legs beyond the initial reaction.
