The model's market view
Risk-on rebound day. US indexes are up about 0.6-1% after a heavy tech sell-off last week; on Friday the Nasdaq fell 2.86% and SOXX fell 8.2%. WTI crude is down 4-6% to below $100 after reports that a draft proposal to end the US-Iran war is circulating, following Iran-Qatar talks. Three things fall inside the window: Apple and Palantir report after the close today, the US midterm elections are on Tuesday, and the window ends at 10:44 ET Tuesday. The picks favour oversold, higher-beta semiconductors that could keep recovering, plus large caps with fresh beat-and-raise earnings, which can drift higher after the report and depend less on the AI-capex debate. Main risks: analysts warn that US/Israeli strikes on Iran could resume after the midterms, which would reverse the oil drop. A weak Apple or Palantir report could also restart the tech sell-off. I avoided IDXX and CRWD because both have given back their early gains today despite good news.
Why each pick
MAR
Thesis: Marriott beat Q3 estimates. Adjusted EPS was $3.02 against about $2.85 expected, and revenue rose 8% to $7.0B. It raised its 2026 global RevPAR outlook to 4.5-5% from 3-3.5% and lifted FY EPS guidance to $12.07-12.14, above consensus near $11.73. Its Q4 EPS guidance is also above estimates. The shares are at a new 52-week high, and lower oil helps travel demand at the margin. A large-cap beat-and-raise near highs tends to keep drifting up for a session. Risks: the stock is already up about 4% today, so some of the gain could be given back. Also, if Iran tensions flare after the midterms, travel names could sell off. Price: intraday quote of about $420 (+4%) reported early in today's session, not a closing price.
EL
Thesis: Estee Lauder beat fiscal Q1 clearly. Adjusted EPS was $0.72 against $0.51 expected, and revenue was $3.72B against about $3.65B. Organic sales grew 6% and adjusted operating margin rose 480bp to 12.1%. The company raised FY27 organic growth guidance to 4.0-5.5% and adjusted EPS guidance to $3.20-3.45, and noted strength in China and fragrance. The stock is at the day's high and near its 52-week high of $121.64. Its exposure is mostly unrelated to the AI and oil swings, which diversifies the basket. Risks: it trades on a very rich P/E, and it could lag if money rotates hard back into tech after Apple. Price: Robinhood intraday quote of $114.00, at the session high.
SMH
Thesis: semiconductors are bouncing after SMH fell 6.98% on Friday and about 16% over the past month. The S&P 500 semiconductor index's forward P/E has dropped to about 14.7x, below the S&P 500's 18.9x. SMH has a beta of about 1.8, so it should outperform if the relief rally continues and the midterms pass without disruption, since post-midterm periods have historically been favourable. Risks: AI-capex worries are still driving the sector, and a weak Palantir or Apple reaction tonight could restart the sell-off. Some commentators expect the chip sell-off to go further. Price: delayed intraday quote from Finviz of $530.22 (+1.48%) at 10:43 AM ET.
MU
Thesis: memory stocks are leading the AI rebound. Micron fell about 17% over the past month and is bouncing about 2% today. It trades near 12x trailing earnings and about 6x annualised next-quarter EPS guidance, and the average analyst target is far above the current price. With a beta near 1.9, it gives the basket extra upside if tech keeps recovering. Risks: it overlaps with SMH. Its MACD and other momentum indicators are still negative, and the stock sits below its 20- and 50-day averages. It is also sensitive to any further slide in AI-capex sentiment. Price: Robinhood intraday quote of $898.00 (session range $895.71-$905.79).
UAL
Thesis: jet fuel is United's biggest swing cost. WTI is down about 6% to under $100 after Iran's president said the supreme leader had given the government authority on peace talks, and a draft proposal is circulating with a follow-up meeting possible. If diplomacy keeps moving forward, airlines could extend their gains. The stock is still well below its 52-week high of $138.77 and has a consensus target near $156. Risks: this is the most binary pick. Analysts expect strikes on Iran could resume after Tuesday's midterms, and Goldman has raised its oil forecasts. Any escalation headline would quickly reverse today's roughly 6% gain. Price: MarketBeat delayed intraday quote of $110.55 (+6.05%) as of 10:08 AM ET.
