FUM Daily Market Digest — Wednesday, September 9, 2026
Wednesday's selling was broad and deliberate. Nine of eleven SPDR sectors declined, the Russell 2000 dropped 1.37%, and the breadth data reinforced the headline weakness: for every stock that rose, 3.4 fell. Semiconductors stood apart, with SOXX advancing 0.68% — the lone bright spot in an otherwise uniform retreat.
The Dow Jones Industrials fell 0.75%, the S&P 500 shed 0.46%, and the Nasdaq 100 managed a contained 0.29% decline as large-cap technology names absorbed some of the pressure. The Dow Jones Transportation Average fared worse, sliding 1.52%, while the Russell 2000 took the sharpest hit in the index complex with a 1.37% loss. No trend signals changed at Wednesday's close. DIA, SPY, and QQQ maintain short-term UP signals. IYT, IWM, and SOXX hold short-term DOWN signals. The split between large-cap UP signals and small-cap DOWN signals has persisted for several sessions — a structural divergence that reflects selective recovery rather than broad-based momentum.
The FUM Market Strength Indicator fell 2.75 percentage points to 45.74%, extending a 17-session erosion from the August 14 peak of 70.04%. The indicator has shed 24.30 points from that high, crossing the 60% bullish threshold between August 25 and August 28 without recovering it since. Wednesday's decline accelerated past the 17-session average of 1.43 points per day. At the current pace, the 40% bearish floor is roughly four sessions away — and the acceleration narrows that window further.
Individual-name breadth confirmed the session's character. Of 814 tracked names, 182 advanced against 616 decliners. Volume reached approximately 4.87 billion shares — active participation with sellers firmly in control. The Nasdaq's relative stability concealed significant deterioration at the stock level; the headline numbers understated the scope of the pullback.
Energy was the session's only SPDR gainer, adding 0.83%, and remains the single sector meeting the full 2-3 week leadership criteria: breadth at 100% and a 20-day momentum delta of +16.13 points. Financial Services was the only sector showing accelerating breadth on both the 1-day and 5-day measures, though its 20-day delta of −18.06 places it in rollover territory — short-term improvement against a deteriorating medium-term trend.
Consumer Defensive absorbed the sharpest single-session breadth drop, plunging 13.16 points to 44.74%, one day after XLP flipped to a DOWN short-term signal. Consumer Cyclical continued its medium-term unwind with the steepest 20-day breadth erosion in the SPDR universe at −39.89 points. Industrials and Real Estate breadth sit at 21.25% and 7.14%, respectively — both ETFs in DOWN short-term signals. No sector outside Energy carries a 20-day breadth delta above +15, leaving no rotation destination with medium-term conviction.
A sustained close back above 48–50% in the MSI is the first signal that broad participation is stabilizing. Without it, the near-term path continues toward bearish breadth territory below 40%. Energy remains the one sector where trend, breadth, and momentum align — an isolation that reflects how uneven the broader market has become.
