Dangerous pullback in S&P 500 and Nasdaq 100: will FOMO and TACO trade return?
S&P 500 and Nasdaq 100 perform a pullback to previous resistance levels. Divergences, overbought conditions, lack of breadth, and VIX approaching 20% may negate FOMO and the TACO trade. Read the analysis

Exhaustion formations in the bullish trend
The falls in US indices last Friday triggered bearish engulfing patterns on the weekly charts. These formations point to fatigue in the previous bullish trend and have pushed daily price oscillators lower against their signals. In many cases, bearish divergences have also appeared and overbought levels remain elevated.

For now, pullback to the SMA (50) and August 2025 highs
Friday's fall was broad, although it was somewhat magnified because the market had become used to very narrow trading ranges. Even so, the indices have so far found support at the first reasonably meaningful support levels.
The SMA (50) and the August 2025 highs, previous resistance levels that have now become support, have managed to halt the falls in the US NDAQ 100, US SPX 500 and US 30. As long as these supports hold, the correction may still be interpreted as a pullback towards important levels.
That pullback may tempt some traders to rejoin the underlying bullish trend from a short-term perspective. It is a familiar pattern from recent months, especially for traders drawn in by the TACO trade and fear of missing out (FOMO).

Concentration and lack of breadth
There are, however, signs of maturity in the broader bullish trend that argue for caution and make this pullback look more dangerous.
The lack of breadth is one of the clearest divergences. The gains have been concentrated in a small number of stocks, while many others have fallen behind. One way to see this is to look at the percentage of stocks trading above the most widely followed moving averages.
In the case of the S&P 500, and using the data published by Barchart, the index remains above the SMA (50), but most of its constituents are already trading below it.

Overbought conditions and VIX near 20%
Overbought conditions are another excess that may still need to be unwound. The distance between the indices and the SMA (200) is around 6% for the US 30 and 11% for the US NDAQ 100. That is an attractive gap for traders looking for a deeper correction and a reversion towards the long-term average.
The distance from support and the overbought backdrop may increase selling pressure if the lows from last week are broken. That kind of break may look more reliable if it is accompanied by the VIX moving decisively above the 20% threshold it is currently testing.

ECB raises rates as Eurozone stagflation risk deepens
The ECB has delivered the 25-basis-point rate rise flagged in the Spanish source, but the move lands in an uncomfortable mix of weaker growth and higher inflation projections. With energy costs still driving the shock, the euro and European equities may remain sensitive to every hint on the next rate move.
US inflation above 4% puts the Fed and AI trade under pressure
The US inflation risk flagged in the Polish source has now materialised, with May CPI rising 4.2% year on year as energy costs bite. The result leaves Fed Chair Kevin Warsh facing an early credibility test, while higher yields and funding costs could challenge the AI-led Nasdaq trade.
DAX stabilises while Wall Street recovers faster from Middle East escalation
The DAX is stabilising after a sharp loss as markets digest the latest escalation in the Middle East, but the reaction has so far stayed more contained than the jump in energy prices might suggest. Oil prices, EUR/USD and the length of the conflict are now likely to shape whether Europe can absorb the shock as easily as Wall Street.
