[MARKET ANALYSIS] European bourses reverse Monday's gains as disappointing AAPL and PLTR guidance weighs on tech names

• European bourses (Stoxx 600 -0.4%) begin Tuesday’s trade on the back foot, reversing the broad gains seen on Monday. Crude benchmarks have pared some of Monday’s c.8% losses, after reports that the US hit Qeshm Island and a senior Iranian official told Reuters that a deal is still out of reach. To add to the downbeat tone were disappointing earnings from Apple and Palantir (see more below).
• Sectors have a negative bias. Defensive sectors lead, with Health Care topping the sector pile. The sector laggard is Basic Resources, with Tech and Media following closely behind.
• Key movers include: Bayer, Q3 metrics beat and raised its FY adj. EBITDA guidance; Lufthansa, trimmed its FY adj. EBIT guidance while lifting its fuel bill; Philips, sales beat while reiterating its FY outlook and announcing a settlement with the US DoJ regarding faulty sleep apnoea devices; Shell, sold its NWS stake to XRG for USD 1.45bln; Schaeffler, to close five sites in Europe resulting in job cuts of 3,460.
• US equity futures follow their European counterparts lower, not helped by Apple and Palantir earnings. Starting with Apple, it gave a mixed report, with tightening FY gross margin guidance (45-46%, exp. 47%) overshadowing an upbeat sales forecast (7-10%, exp. 6.1%). As a result, shares are lower pre-market by 4.5%. For Palantir (-5.1% pre-market), its outlook also disappointed, as it expects Q4 sales that point to a slower rate of growth.

A one-day reversal of a broad relief rally on index-level disappointment from a handful of heavyweight earnings is a familiar pattern: when the tape's leadership is concentrated, soft guidance from a couple of bellwether names is usually enough to flip sector breadth, and defensives topping the board with health care leading and tech and resources lagging is the textbook rotation signature. The margin-guidance miss at the largest index constituent matters more than the revenue beat precisely because gross margin is the line that feeds the entire earnings base, and in past episodes of this kind the drag transmits through the cap-weighted complex and the futures rather than being contained in the single name. The crude leg is the less durable one: partial retracements of sharp geopolitical moves after reports of fresh strikes have historically faded unless flows through the affected waterway or infrastructure are actually interrupted, so the tell is freight, insurance and the front of the curve rather than the headline itself. The corporate tape is stock-specific: guidance raises rewarded, airline margin pressure via the fuel bill, and a long-running device liability finally settled, each of which tends to trade idiosyncratically once the macro tone is set. Follow-ons of note are whether the US cash session confirms the pre-market marks, whether the guidance cuts cluster into an earnings-season read on margins, and any confirmation or denial on the Gulf reporting.
