The model's market view
US equities are trading higher intraday, supported by relief that the Fed hike was largely priced in, a sharp rebound in semiconductors, and a crypto-linked rally. The S&P 500 is modestly positive, but triple witching and falling oil prices add cross-currents. Momentum favors high-beta tech and crypto-exposed names, though leverage and regulatory risks remain.
Why each pick
SOXL
SOXL, the 3x leveraged semiconductor bull ETF, is riding a powerful sector rotation into semiconductors after the Fed decision. The fund was up over 10% in the prior session and remains in demand as chip stocks continue to lead. Its high beta to the semiconductor index makes it likely to outpace SPY on a strong risk-on day. Risks include severe leverage decay, high volatility, and the possibility of profit-taking after a sharp two-day run. Reference price is a live intraday quote from Yahoo Finance.
INTC
Intel surged 7.67% in the previous session on AI optimism and foundry progress, and it remains a high-beta momentum name that can outperform SPY on continued semiconductor strength. The stock is seeing active intraday trading and is supported by a broader chip rally. Risks include intense competition, negative earnings, and the potential for a sharp reversal if sector momentum fades. Reference price is a live intraday quote from Yahoo Finance.
COIN
Coinbase is a direct beneficiary of the crypto rally, with Bitcoin hovering near $78,000 and new SEC tokenized-stock policy boosting sentiment. COIN is up over 6% intraday and historically moves with high beta to crypto prices, which can lead to outperformance versus SPY during risk-on sessions. Risks include regulatory uncertainty, crypto price volatility, and the stock's sensitivity to a sudden reversal in digital-asset sentiment. Reference price is a live intraday quote from Yahoo Finance.
AMD
AMD is up over 6% in the prior session and continues to trade higher intraday, supported by reports of chip price hikes and strong AI-driven demand. As a high-beta semiconductor leader, AMD can outpace SPY when the sector rallies. Risks include high valuation, competition from Nvidia, and the possibility of a pullback after a rapid run. Reference price is a live intraday quote from Yahoo Finance.
GOOGL
Alphabet is showing relative strength, up over 2% intraday and benefiting from megacap tech leadership, AI initiatives, and resilient ad spending. In a market where breadth is narrow, GOOGL can outperform SPY due to its heavy weighting and positive momentum. Risks include antitrust headwinds, broader market reversal, and the stock's exposure to regulatory pressures. Reference price is a live intraday quote from Yahoo Finance.
