TL;DR: Haruspex data for August 18, 2026, shows a prevailing bullish market pressure with an average score of 58.1 across 707 stocks. This directional signal is driven by strong Short-Interest and rising Regulatory dimension scores, indicating targeted upward moves even as the S&P 500 sees a slight dip. Investors should focus on stocks exhibiting strong dimension-specific momentum.
On Tuesday, 2026-08-18 ET, market signals indicated a nuanced landscape where broad index movements masked underlying individual stock dynamics. The S&P 500 closed at 7703.66, down 0.53% [data: 2026-08-17 close]. However, Haruspex analysis shows that 68% of the 707 stocks covered exhibit bullish pressure, with the market-wide average score settling at 58.1 out of 100.
Macro Regime Monitor
The broader market context reveals a cautious but not overtly bearish environment.
| Metric | Current | Inline Source |
|---|---|---|
| S&P 500 | 7703.66 | [data: 2026-08-17 close] |
| VIX | 15.80 | [data: 2026-08-17 close] |
| 10Y Treasury Yield | 4.72% | [data: 2026-08-17 close] |
| WTI Crude Oil | $84.79 | [data: 2026-08-17 close] |
| US Dollar Index (DXY) | 99.60 | [data: 2026-08-17 close] |
A VIX at 15.80 indicates a moderate level of market volatility. WTI crude oil at $84.79 suggests ongoing energy costs for businesses, while the 10Y Treasury Yield at 4.72% reflects persistent interest rate concerns. The DXY at 99.60 points to a relatively strong dollar.
What the Data Shows: Granular Bullish Pressures
Haruspex data indicates that bullish pressure is not uniformly distributed but concentrated in specific market dimensions. The overall bullish percentage of 68% signals that a majority of stocks are seeing upward directional signals, even if the main index is flat.
Key Dimensions Driving Market Pressure
- Short-Interest (Avg Score: 62.0): This dimension shows the strongest bullish signal. A high score here indicates that bearish bets against specific stocks are under pressure, potentially signaling short squeezes or a sustained buying interest that is forcing short sellers to cover positions. Top stocks showing this pressure include BA, ASX, and EW.
- Regulatory (Avg Score: 61.7, Change: +1.7): The notable increase of 1.7 points in the Regulatory dimension score suggests positive developments or reduced governmental headwinds for certain sectors or companies. This upward shift is a significant indicator of improving operational environments for stocks such as V, AAPL, and MA.
- Institutional (Avg Score: 61.2): A consistently strong score in the Institutional dimension points to sustained interest and capital allocation from large institutional players. This often provides a stable directional edge, as seen in stocks like MXL, CR, and SHOP.
- Sentiment (Avg Score: 60.5): The positive average score for the Sentiment dimension reflects a generally favorable market mood and positive media or social discussions surrounding stocks. Companies like AM, ET, and CAT are currently benefiting from this positive directional signal.
- Microstructure (Avg Score: 54.8): This dimension, which captures various market mechanics like order flow and liquidity, indicates moderate bullish pressure. Stocks such as MPC, VLO, and BA are exhibiting these specific trading dynamics.
Other dimensions also contribute to the overall picture. The Management dimension saw a slight increase of +0.3, and Climate-Risk edged up by +0.1, suggesting minor improvements in these areas. The Ai-Exposure dimension, with an average score of 52.4, highlights moderate directional signals for stocks heavily involved in artificial intelligence, including AMZN, NVDA, and AAPL.
Why is bullish market pressure dominant despite a flat S&P 500?
Haruspex data isolates granular market mechanics, such as the unwinding of short-interest positions and the emergence of specific regulatory tailwinds. These factors can independently drive significant individual stock performance even when the broad S&P 500 index experiences little movement or slight declines. The market-wide average score of 58.1, coupled with 68% of stocks showing bullish pressure, demonstrates this selective, dimension-driven market dynamic.
Regime Thresholds
The current bullish thesis for individual stocks holds under prevailing macro conditions. A significant deterioration in these levels could alter the market's directional signals.
- The bullish pressure thesis is robust as long as the VIX remains below 18.00, signaling manageable market fear.
- Continued stability in 10Y Treasury Yields below 4.90% would prevent broader market liquidity concerns from overriding stock-specific signals.
- WTI crude oil prices staying below $90.00 will help mitigate significant energy cost pressures for margin-sensitive sectors.
Risk Factors
While bullish signals are prevalent, certain risk factors warrant attention. The S&P 500's slight decline of 0.53% suggests that the bullish pressure is not a broad market tide but rather a selective current, indicating a need for careful stock selection.
- Insider-Trading (Avg Score: 34.8): This dimension shows a strong bearish pressure. A low score here suggests that corporate insiders may be divesting shares, signaling a lack of confidence in near-term prospects. This is a significant contrarian signal for stocks such as TSM, TSLA, and AMZN.
- Concentration-Risk (Avg Score: 45.6): This dimension sits in the neutral range, indicating no significant directional edge. However, it merits watching as elevated concentration risk could lead to instability if key holdings face headwinds.
What Would Change This View
The current market thesis, characterized by selective bullish pressure despite a flat broad index, could be invalidated by specific shifts in key market indicators and Haruspex dimensions.
- If the S&P 500 closes below 7650 for two consecutive trading sessions, it would suggest a broader weakening of market sentiment.
- A sustained rise in the VIX above 18.00 would indicate increased systemic fear, potentially overriding individual stock catalysts.
- A drop in the market-wide average Haruspex score below 55.0, particularly if accompanied by a decline in the Short-Interest dimension below 55.0, would signal a significant reduction in overall bullish pressure.
Outlook
The Haruspex data for August 18, 2026, points to a market environment dominated by specific, dimension-driven bullish pressures. While the S&P 500 remains largely flat, underlying signals from Short-Interest and Regulatory dimensions suggest targeted opportunities. Investors should prioritize detailed analysis of individual stock dimensions to navigate this selective market effectively, paying close attention to both strengthening bullish signals and emerging bearish indicators like Insider-Trading patterns.
