Market SummaryRead ▾

The market opened with broad weakness across growth stocks, with QQQ down 1.85% and semiconductor/tech leveraged plays TQQQ and SOXL cratering 5.66-5.67%. Software took the hardest hit—DDOG plunged 8.5% on SaaS disruption concerns, while cybersecurity names PANW and CRWD fell 6.1% and 5.3% respectively following reports that Anthropic's Claude Mythos could cannibalize traditional vendor models. Geopolitical uncertainty around U.S.-Iran tensions added pressure, dragging cruise lines (NCLH -6.9%, CCL -5.8%) via fuel cost concerns and biotech (MRNA -6.7%) via policy risk. The lone bright spot: ETR surged 7.2% on a Meta power contract win, offsetting weakness elsewhere in utilities.

Recommendation

Avoid catching falling knives in semiconductor, SaaS, and cybersecurity names until volatility settles and AI disruption narratives clarify—valuations are compressing fast. Selectively accumulate defensive/utility plays like ETR and energy-exposed names if geopolitical tensions persist, and watch financials (COIN, HOOD) for capitulation before re-entry. For momentum traders, QQQ and SPY still near key support; consider tactical hedges over outright shorts given the leverage embedded in triple-leveraged ETFs.
