Weekly Market Read · Monday, 26 October 2026

Last week

The week opened on an improving note after the prior Friday's breakdown failed to follow through, but by Thursday the tech-led unwind had reasserted itself. The S&P 500 finished −0.43% and the Nasdaq 100 −0.76%, both settling near their weekly lows, while the Dow Jones gained +0.44% and the Russell 2000 rallied +1.96%. The VIX was −2.70% on the week, closing at 19.45.

That split is the story. The average stock outperformed the index by a historically wide margin — equal-weight versus cap-weight at the 99th percentile over 21 sessions — which is the signature of a concentrated unwind in the largest names rather than broad liquidation. Every broad index closed below its 50-day average, yet the S&P 500 holds +5.0% above its 200-day: a pullback inside an uptrend that remains intact.

Credit carried the cautionary side of the week. High-yield spreads widened 17bps to 3.40% (as of Thursday), a 99th-percentile level, and investment-grade spreads sit at 0.89% (as of Thursday; 96th percentile). Funding stayed orderly (SOFR−IORB at 0bp) and credit-ETF prices held, which keeps this widening-from-tight rather than dislocation. Oil added to the pressure: WTI futures rose 4.29% on the week to settle at $103.27 Friday after a record month of Hormuz ship attacks and claimed strikes on Saudi pipeline infrastructure kept the oil-to-inflation channel live.

What the research is watching

Working in the market's favour are the longer-term trend and the earnings. Large-cap indexes remain above their 200-day averages with the business cycle in mid-expansion and high confidence — a pullback inside an uptrend, which the research flags as historically the strongest short-horizon setup. Peak reporting season has delivered 44 large beats against 3 large misses over the trailing 14 days, with 177 index names reporting this week, and forward P/E at 19.54x is full but supported by those results.

Asking for care are credit and the options market. High-yield spreads are widening from a rare extreme; a core PCE print on Thursday that runs above what the market has priced, or further widening accompanied by a breakdown in the ratio of high-yield to investment-grade bond prices, would turn widening-from-tight into credit-confirmed selling. Dealers are short gamma on both SPY (-3.2M) and QQQ (-2.2M) with spot sitting directly on the put walls, so whichever way prices move after Wednesday, hedging flows push in the same direction — a hold favors a snap-back, a break self-accelerates.

Sentiment and the short-term tape sit between the two: investors read as doubtful rather than fearful, dip-buying remains crowded in semiconductors while gold and small-cap funds saw heavy redemptions, and no index is at an oversold extreme. Wednesday resolves it — whether the Fed's language validates the December-hike pricing that drove the month's derating, with Microsoft and Alphabet capex guidance landing in a short-gamma, backwardated-vol market the same afternoon. Fundamentals and the intact longer-term trend are working in the market's favour; the credit picture and options positioning are asking for care; sentiment and the short-term price trend are undecided.

The week ahead

The coming week is the quarter's densest. Tuesday opens with durable goods and new home sales. Wednesday 2026-10-28 brings the Fed decision at 14:00 ET alongside Microsoft and Alphabet earnings, with markets pricing an October hold and a December hike. Thursday 2026-10-29 stacks core PCE, Q3 GDP, jobless claims and Amazon/Eli Lilly, and Friday brings Exxon and Chevron — 177 index names report in five sessions.

The one question the week answers is whether the Fed confirms the December hike that drove October's derating and whether mega-cap guidance sustains the earnings cushion, into a market where dealer hedging amplifies whichever direction prices take first. Last week's improvement was in velocity — a slower decline, a lower VIX — not in structure, with credit at an extreme and every index below its 50-day average. The research does not forecast the outcome; it reads Wednesday as the point at which the structure either reasserts itself or gives way.
