TL;DR: The market closed the week ending August 17, 2026, with 75% of stocks showing bullish pressure despite the S&P 500's slight dip.

Winners of the Week: Identifying Bullish Pressure
Among the 333 stocks analyzed, a distinct group demonstrated rising bullish pressure. The data reveals specific dimensions contributed to these shifts, often reflecting robust short-term interest and positive sentiment flows.
What drove Alibaba's strong weekly performance?
Alibaba Group Holding (BABA) surged with its score improving by 16.0 points to 65.0, signaling strong bullish pressure. Trading at $123.81 [data: 2026-08-17 close], a 1.35% gain today, its current price sits above the 52-week low of $91.99, but below the $192.67 high. Haruspex data detected a sharp increase in the options_flow dimension, which rose 22 points, combined with a significant improvement in social_sentiment, up 18 points. This suggests increased speculative interest and a more positive retail narrative forming around the stock.
Marsh & McLennan Companies (MMC) saw the largest weekly score improvement, climbing 17.0 points to 65.0. This places MMC firmly in the bullish pressure category. The primary drivers were a 25-point rise in the institutional_flow dimension, indicating robust buying from larger entities, and a 15-point increase in the technical_momentum dimension. This reflects growing investor confidence and positive price action.
Activision Blizzard (ATVI) also experienced a notable uplift, with its score rising 10.0 points to 58.0, shifting into a bullish pressure zone.

Uber Technologies Inc. (UBER) gained 8.0 points, reaching a score of 63.0 and signaling continued bullish pressure. Harupsex data shows the technical_momentum dimension advancing 16 points.

The options_flow dimension surged by 12 points, alongside a 9-point increase in the analyst_revisions dimension. This combination suggests strong institutional and analyst conviction driving the market's directional signal.
Losers of the Week: Identifying Bearish Pressure
Conversely, a significant number of stocks experienced declining market pressure, with several shifting from neutral or even bullish stances to more bearish outlooks. This highlights selective investor caution.
International Business Machines (IBM) registered the most significant decline, dropping 26.0 points to a neutral score of 48.0. Trading at $234.32 [data: 2026-08-17 close], down 1.19% today, IBM has moved away from its 52-week high of $332.46. Haruspex analysis detected a 28-point drop in the technical_momentum dimension, indicating a loss of upward trajectory. Concurrently, the short_interest dimension rose 15 points, signaling increasing bearish bets against the stock.
Coinbase Global Inc. (COIN) also suffered a sharp 26.0-point decline, bringing its score to 44.0, indicating bearish pressure. Trading at $148.47 [data: 2026-08-17 close], down 3.53% today, its current price is significantly below its 52-week high of $402.16. The social_sentiment dimension fell 20 points, reflecting waning retail enthusiasm, while the regulatory_pressure dimension increased by 18 points. This suggests growing concern over potential regulatory headwinds impacting the crypto exchange.
BlackRock Inc. (BLK) saw its score fall by 25.0 points to 53.0, moving to a neutral directional edge. The institutional_flow dimension dropped 20 points, indicating some institutional outflows or reduced buying interest. Simultaneously, the news_sentiment dimension decreased by 15 points, reflecting potentially less favorable market narratives impacting the asset manager.
Marriott International (MAR) experienced a 23.0-point decline, settling at a neutral score of 55.0.

Moreover, the interest_rate_sensitivity dimension increased by 10 points, highlighting growing concern about rising borrowing costs for utilities.
Market Sentiment Shift: A Rotation Underneath a Flat Index
Despite the S&P 500's flat performance, the underlying market sentiment saw a distinct rotation. The average Haruspex score for the 333 analyzed stocks remained at 59.0, indicating a generally bullish leaning. However, the disparity between only 10 biggest gainers and 135 biggest losers by score change points to a highly selective market. Capital flowed actively towards specific narratives and away from others.
The prevalence of bullish signals, with 75% of stocks showing positive directional pressure, suggests that dips in the broader index are being met with targeted buying in favored names. This indicates a market that is not broadly defensive but rather discerning, rewarding strong fundamental or narrative-driven shifts detected by Haruspex dimensions.
Key Takeaways
- The market displays strong underlying bullish pressure in specific stocks, despite a flat S&P 500.
- Tech and financial services experienced significant rotations, with notable gainers like BABA and significant decliners like IBM and COIN.
- Haruspex dimensions like options_flow, institutional_flow, and social_sentiment proved critical in identifying these shifts.
- The subdued VIX and stable 10-Year yield offer a calm macro environment, allowing individual stock narratives to drive movement.
What Would Change This View
The current thesis of a rotational market with underlying bullish pressure faces specific invalidation conditions. If the S&P 500 closes two consecutive weeks below its 50-day moving average on above-average volume, the broader bullish pressure could erode. A sustained breach of the 10-Year Treasury Yield above 5.0% would also introduce significant headwinds, particularly for growth sectors.
Furthermore, an unexpected spike in the VIX above 20.0 could signal a significant increase in systemic risk, overriding individual stock signals and pushing the market into a broader risk-off posture. These measurable conditions serve as critical checkpoints for the current market perspective.
Week Ahead Outlook
As the market enters a new week, attention will likely remain on individual stock narratives and sector-specific data. Haruspex data indicates continued selective buying. Traders should monitor shifts in options_flow and institutional_flow dimensions for early signs of momentum. Any significant economic data releases could also impact the stable macro environment and potentially alter current directional signals. The current low VIX suggests complacency could be quickly tested.
