Warning Sign? S&P and Nasdaq Flash Outside Reversal Patterns

/in , /by

Market Pulse – July 31, 2025

Here are a few key charts that capture today’s market story.

We start with the S&P 500 heatmap for Thursday. Outside of a handful of Big Tech names – most notably META and Microsoft, which delivered standout earnings -the broader index was awash in red.

ORCL enterprise software and infrastructure stocks perform positively in the tech sector, reflecting growth trends; AMD and NVDA semiconductors decline amid market fluctuations.

Despite strong results from those leaders, both the Nasdaq and S&P 500 posted what’s known as outside reversal days.

Here’s what that means specifically:

‘Outside day’:
The day’s high is higher and low is lower than the previous day’s range – so it completely ‘engulfs’ the prior day’s trading range.

‘Reversal lower’:
The index closes below the previous day’s close, despite opening strong (and possibly making new highs intraday).

S&P 500 – Outside Reversal

What it suggests:

  • Early strength was overwhelmed by selling pressure, showing a loss of momentum.
  • Outside reversals to the downside often act as short-term warning signals—especially during extended rallies.
  • When combined with heavy volume, it can add conviction to the bearish setup.

This doesn’t guarantee a major top, but it raises a caution flag that a pullback or period of consolidation may be near.
