Broadcom is similarly benefiting from the hyperscaler capex cycle. Options activity shows extreme call bias across the sector, with call-to-put ratios reaching 3.03 on NVIDIA. The SOXX index, a semiconductor-focused benchmark, has surged 72.88% year-to-date and is approaching 52-week highs.

The implications extend across the broader tech and AI ecosystem.
