The model's market view
As of November 2, 2026, the US equity market faces elevated event risk following the October 30 technology selloff, when concerns about AI infrastructure spending and valuations weighed heavily on semiconductor and software stocks. The next 24 hours contain confirmed earnings events for Palantir, Apple, onsemi and Vertex Pharmaceuticals after Monday's close, plus Shopify before Tuesday's open. This creates opportunities for directional earnings gaps but also substantial uncertainty. My preferred hypotheses are downside earnings risk for PLTR and ON, positive earnings relief for SHOP and AAPL, and continued fundamental momentum for VRTX. These are forecasts of additional movement from the verified intraday quotes, not predictions of price changes already realized. The authoritative window remains 2026-11-02T15:35:00.621Z through 2026-11-03T15:35:00.000Z. All historical statistics use the 20 completed US Eastern regular sessions ending October 30, excluding November 2. The 20-day dollar-volume figures are calculated as the arithmetic mean of daily closing price multiplied by share volume. These are approximations of daily traded dollar turnover, not calculations using every intraday transaction. No earnings outcomes scheduled after the prediction time are assumed known. Equal-weight directional returns are scored against SPY, excluding fees, slippage, dividends and borrow costs.
Why each pick
PLTR
THESIS: Forecast DOWN 4.5% from the verified $186.92 quote through the remaining window. Palantir's third-quarter earnings announcement is officially scheduled for after the November 2 close, followed by a 5:00 PM EST webcast. The announcement has not occurred at prediction time. The company previously indicated strong revenue growth, but substantial expectations are embedded in its valuation. My inference is that guidance or margins may fail to justify the existing valuation, producing a negative earnings reaction even if reported growth remains strong. A strong earnings beat and raised guidance are the principal upside risks.

return_5d_pct=-6.42; high_20d=212.94; low_20d=180.81; avg_volume_20d=23056771 shares. The five-session return compares October 30 with October 23. History: https://stockanalysis.com/stocks/pltr/history/
PRICE ACTION: October 30 produced a large negative candle, closing $9.52 below its open and close to the lower part of the daily range. Volume was 27.07 million shares versus the 20-session mean of 23.06 million. This is consistent with selling pressure but not definitive evidence of further declines. The completed sessions show lower highs and weakening closes. The stock remains below its $212.94 20-session high, with $180.81 as the observed lower boundary. The strongest counter-evidence is the sharp lower wick on October 30, which indicates some buying below $184, combined with strong prior business growth.
INTRADAY EVIDENCE: latest_price=186.92 USD; quote_time=2026-11-02T15:31:00Z; quote_status=regular-session real-time-labelled; quote_source=https://stockanalysis.com/stocks/pltr/history/. PARTIAL SESSION as of 2026-11-02T15:31:00Z: open=186.52, high_so_far=186.95, low_so_far=181.63, cumulative_volume=9081739 shares. The stock was approximately 1.53% above the previous close at that quote. This rebound was already observed before the earnings event and is not counted as the forecast upside. Relative intraday volume cannot be established without a comparable time-of-day baseline.
EVENT PATH: Before the scheduled earnings event, the stock declined from its October 23 close of $196.75 to $184.11 on October 30, then rebounded intraday. These changes are observed price action, not a measured reaction to unreleased earnings. pre_event_price=null; observed_event_to_quote_pct=null. No post-event price reaction yet exists. The negative forecast applies only after the current quote. The strongest fundamental counterargument is that continued rapid adoption of Palantir's AI software could support expectations and reverse the selloff. Invalidation would be an earnings-driven recovery above the verified October 30 high of $193.92 supported by stronger-than-expected guidance. General market recovery and short covering are additional emotional-continuation risks. Market capitalization evidence: https://stockanalysis.com/stocks/pltr/market-cap/.
SHOP
THESIS: Forecast UP 4.0% from the verified $158.96 quote. Shopify officially scheduled third-quarter results before the November 3 open, with an 8:30 AM EST conference call. The results are not yet known. The positive thesis is a potential earnings-relief rebound after the previous week's heavy selling. Shopify's earlier reported growth across gross merchandise volume, revenue and free cash flow supports the possibility that underlying commerce demand remains robust. This is a fundamental expectation rather than confirmation of third-quarter performance. A disappointing holiday-quarter outlook or margin pressure could instead produce a substantial decline.

PRICE ACTION: Shopify declined substantially over five completed sessions. On October 30 it opened at $161.89, reached $154.26 and finished at $157.49. The lower wick indicates buying interest after the intraday low, although the closing position remained weak. The 10.54 million shares traded exceeded the 7.98 million 20-day mean. This combination reflects significant disagreement among market participants, not a mechanical rebound signal. The October 30 low is relatively close to the 20-day low of $151.70, while $180.88 is the established upper extreme. The strongest counter-evidence to the upside forecast is persistent lower highs and the high-volume selling on October 30.
INTRADAY EVIDENCE: latest_price=158.96 USD; quote_time=2026-11-02T15:32:00Z; quote_status=regular-session real-time-labelled; quote_source=https://stockanalysis.com/stocks/shop/history/. PARTIAL SESSION as of 2026-11-02T15:32:00Z: open=158.29, high_so_far=160.58, low_so_far=157.60, cumulative_volume=2402029 shares. The quote was 0.93% above Friday's close, suggesting an early stabilization attempt. This increase has already occurred and is excluded from the expected future move. Comparable same-time-of-day historical volume is unavailable, so relative intraday volume cannot be verified.
EVENT PATH: The substantial decline into October 30 occurred ahead of the officially scheduled November 3 earnings report. No third-quarter results or post-report reaction were available at prediction time. pre_event_price=null; observed_event_to_quote_pct=null. My inference is that pessimistic sentiment may have reduced the threshold for a favorable earnings reaction, but neither a beat nor a rebound is confirmed. A credible improvement in growth expectations would support further upside after the report. Invalidation would be renewed selling below the verified $154.26 October 30 low, especially if results or guidance indicate weakening growth or profitability. A rebound driven only by short covering without favorable business developments could reverse quickly. Market capitalization evidence: https://stockanalysis.com/stocks/shop/market-cap/.
ON
THESIS: Forecast DOWN 3.5% from the verified $74.37 quote. onsemi reports third-quarter financial results after the November 2 close, with a confirmed 5:00 PM EST conference call. The key uncertainty is whether automotive and industrial semiconductor demand, revenue mix and profitability support market expectations. The company has not yet disclosed this quarter's earnings outcome. The bearish hypothesis is that the current intraday rebound proves vulnerable to weaker guidance or continued sector-wide repricing. However, a strong earnings report could amplify the observed recovery, making this a relatively low-confidence bearish call.

PRICE ACTION: The October 27 advance to $79.29 failed to hold, followed by declining highs and the October 30 selloff. The latest completed session declined 4.74%, on 16.57 million shares compared with the 20-day mean of 10.12 million. The October 30 candle had a noticeable lower wick from $69.64 to the $71.67 close, demonstrating buying pressure after the low. That wick is the strongest completed-session counter-evidence against immediate bearish continuation. The 20-session price range of $69.64 to $86.92 highlights substantial volatility. A temporary rebound after the selloff is not itself proof of a durable recovery.
INTRADAY EVIDENCE: latest_price=74.37 USD; quote_time=2026-11-02T15:30:00Z; quote_status=regular-session real-time-labelled; quote_source=https://stockanalysis.com/stocks/on/market-cap/. The price was approximately 3.77% above the previous close, and that appreciation is already realized rather than forecast. PARTIAL SESSION from the separately timestamped 2026-11-02T15:21:00Z quote snapshot: open=72.22, high_so_far=73.36, low_so_far=71.55, cumulative_volume=1421392 shares; source=https://stockanalysis.com/stocks/on/. These earlier partial-session extrema and volume must not be treated as synchronized with the later $74.37 quote. A later price above the earlier high simply shows the partial snapshot became stale. Relative intraday volume remains unverified without a time-matched historical baseline.
EVENT PATH: The earlier decline and November 2 rebound precede the scheduled earnings announcement. No actual earnings response is available. pre_event_price=null; observed_event_to_quote_pct=null. The bullish response visible before the event may reflect anticipation and short covering, but its cause cannot be verified from price action alone. My forecast expects further post-quote downside if the report does not demonstrate a convincing recovery in operating fundamentals. The strongest observed counter-evidence is the intraday rise to $74.37, which may indicate improving investor willingness to own the stock ahead of results. Invalidation would be an earnings-supported move above the verified October 27 high of $79.29 or materially stronger guidance that changes the demand outlook. Market capitalization evidence: https://stockanalysis.com/stocks/on/market-cap/.
VRTX
THESIS: Forecast UP 3.2% from the verified $564.72 quote. Vertex has two distinct catalyst components: previously released positive Phase 3 RAINIER clinical results and its upcoming November 2 quarterly earnings announcement. The clinical evidence is observed, while tonight's earnings and any outlook revisions remain unknown. On October 23 Vertex reported that povetacicept achieved a statistically significant reduction in proteinuria versus placebo and reaffirmed a November 30 FDA target action date for potential accelerated approval. These observed findings strengthen the clinical narrative, although regulatory approval is not guaranteed. My forecast expects positive pipeline expectations and potential favorable earnings commentary to support additional appreciation.

PRICE ACTION: Vertex advanced over its last four completed sessions, with rising closes of $517.49, $521.03, $529.69, $540.00 and $558.88 across the five-bar sequence. On October 30, a positive gap was followed by a strong close toward the upper part of the range. Volume reached 3.03 million shares, approximately 2.17 times the completed 20-session mean. This is evidence of stronger participation in the advance, not proof of sustainable upside. The previous 20-session high was $563.80. The strongest price-action counterargument is that the rally has already been substantial and could reflect considerable optimism ahead of earnings.
INTRADAY EVIDENCE: latest_price=564.72 USD; quote_time=2026-11-02T15:28:00Z; quote_status=regular-session real-time-labelled; quote_source=https://stockanalysis.com/stocks/vrtx/. PARTIAL SESSION as of 2026-11-02T15:28:00Z: open=560.88, high_so_far=568.67, low_so_far=559.49, cumulative_volume=538374 shares. The stock was approximately 1.04% above the prior close. Its partial-session high had exceeded the completed 20-session high, suggesting a possible breakout. This observed move is already reflected in the latest quote and is not counted again in the forecast. Relative intraday volume cannot be established without matched historical intraday observations.
EVENT PATH: The positive RAINIER results were publicly reported on October 23; the subsequent advance may partially reflect those results, but attributing all of it to the clinical announcement is unsupported. A verified immediately pre-announcement trading price was not established, so the precise event reaction cannot be calculated. pre_event_price=null; observed_event_to_quote_pct=null. The upcoming November 2 earnings report is a separate event and has not occurred. My forecast requires further favorable business or pipeline expectations beyond those already reflected in $564.72. The main counter-evidence is the extended five-session rally, elevated October 30 volume and proximity to recent highs, all of which increase sell-the-news risk. Invalidation would be an adverse financial or pipeline update accompanied by a decline below the verified October 30 low of $549.89. A surprisingly cautious outlook, regulatory uncertainty or profit taking could reverse the anticipated continuation.

Market capitalization evidence: https://stockanalysis.com/stocks/vrtx/market-cap/.
AAPL
THESIS: Forecast UP 2.3% from the verified $340.43 quote. Apple officially scheduled fiscal fourth-quarter 2026 results for November 2 after the close, with its investor call at 5:00 PM EST. The quarter includes the initial sales period for Apple's latest iPhone lineup. The bullish hypothesis is that reported demand and holiday-quarter commentary could outperform currently cautious expectations. However, the earnings figures and management guidance remain unknown. Memory costs, product pricing and consumer demand are meaningful risks that could produce a negative gap instead.

PRICE ACTION: Apple traded largely sideways during October 26-29 before October 30 produced a wide-range decline. Friday's $334.35 intraday low was followed by a recovery to $344.63, forming a substantial lower wick. This suggests some buyers defended lower prices during the market-wide selloff. Volume of 67.84 million shares significantly exceeded the 40.41 million 20-session mean, indicating unusually active full-session participation. Nevertheless, the lower wick does not guarantee a rebound, and the latest close remains below the preceding session's close. The strongest bearish evidence is October 30's heavy-volume selling and today's continued weakness. The $351.73 high and $330.62 low frame the 20-session price range.
INTRADAY EVIDENCE: latest_price=340.43 USD; quote_time=2026-11-02T15:35:00Z; quote_status=regular-session real-time-labelled; quote_source=https://stockanalysis.com/stocks/aapl/. PARTIAL SESSION as of 2026-11-02T15:35:00Z: open=342.67, high_so_far=343.80, low_so_far=339.61, cumulative_volume=10737539 shares. Apple was approximately 1.22% below its October 30 close. This decline has already occurred and cannot be counted as an anticipated move after the current quote. Comparable same-time-of-day historical volume is unavailable, so relative intraday volume is undetermined.
EVENT PATH: Before earnings, Apple traded down from $348.91 on October 29 to $344.63 on October 30 and then to $340.43 at the latest intraday quote. The decrease is an observed pre-earnings movement, not a reaction to the unreleased results. pre_event_price=null; observed_event_to_quote_pct=null. My inference is that some caution may already be reflected in the price and that stronger sales or guidance could prompt an additional rebound. The key counterargument is that valuation expectations remain substantial despite the pullback, so even solid reported results may not satisfy investors. Invalidation would be disappointing earnings or holiday-quarter commentary accompanied by a break below the verified October 30 low of $334.35. The expected upside is a forecast for the remainder of the stated window, not a claim that any earnings-driven gap has already occurred.
