Stock Market Update Thursday August 21, 2025 Markets remained cautious into Jackson Hole. The S&P 500 (SPX) slipped logging its fifth consecutive decline, though cumulative losses over the stretch remain contained at under 2%. NASDAQ 100 (QQQ) fell 0.5%, while small caps (IWM) managed a 0.2% gain, highlighting some relative rotation beneath the surface.
Away From Stocks: Treasurys came under pressure ahead of Fed Chair Powell’s Jackson Hole keynote (8AM local, 10AM ET Friday). The 2-year yield pushed to 3.79%, while the 30-year rose to 4.92%, reflecting a cautious repricing at both ends of the curve.
Commodities and crypto moved mixed:
WTI crude climbed back above $63/bbl, extending its rebound.
Gold eased to $3,338/oz amid firmer yields.
Bitcoin drifted lower to $112,000.
VIX edged toward 17, signaling a modest uptick in implied volatility into the Fed event.
Trading Strategy Overview: Our framework is long-only, with no short exposure to growth stocks or broad equity indices. Positioning is guided exclusively by our proprietary signal-driven indicator, which dictates entry and add-on points.
Execution Rules
Initiate or scale into long positions only upon generation of a buy alert.
Maintain existing positions unless a sell signal is triggered.
No short-selling; capital remains in cash during periods without active buy signals.
Current Signal Update: As of today, our algorithm generated a sell alert for Palantir (PLTR). Accordingly, we exit the position with a very nice profit and move to the sidelines, awaiting the next buy confirmation to either reinitiate exposure or add incrementally.
Forward View: The strategy remains in capital preservation mode until the next actionable signal emerges. This systematic, rules-based approach ensures discipline, removes discretionary bias, and aligns portfolio construction with our proprietary momentum/flow model.
Traders will be closely monitoring the Jackson Hole Economic Symposium, with heightened focus on Fed Chair Jerome Powell’s speech at 10:00 AM ET on Friday, August 22, 2025. Over the past week, equities have traded lower, with the major indices off roughly 2%, as investors adopt a defensive stance ahead of the event.
