SPY is near a 52-week high with low 5-session dispersion while software and cyber show large relative pullbacks after strong prior active returns; CPI/PPI land inside the week and a 58% hike probability plus hawkish Fed dissent raise rate-sensitive risk, so the week is mixed rather than a clean continuation or reversal tape.

SPY is near a 52-week high with low horizon vol while cross-asset 5-session returns are wide (oil/crypto/EM vs software/cyber/defense). Sticky PCE, mixed payrolls with downward revisions, and 58% implied odds of a September hike plus a mid-window FOMC create a mixed one-month setup rather than a clean continuation or reversal regime.

SPY is near a 52-week high with modest 5-session gains while 5s active-return dispersion is only 2.20% and equal-weight lags. The window includes unknown NFP (Sep 4) and CPI (Sep 11) plus Labor Day, so mega-cap beta is fragile. Oil and Brazil show short continuation after large moves; several high-quality names (cyber, metals, silver, biotech, semis) show sharp relative pullbacks after stronger prior windows.

SPY is near a 52-week high with modest 5-session gains while many cyclicals, tech, and defense names show larger recent drawdowns; incoming payrolls, CPI, and the mid-September FOMC create two-way event risk, so one-month outcomes look mixed rather than a clean continuation or reversal regime.

SPY is in a three-session decline into a dense labor/inflation week with rising Treasury yields, while oil jumped on Hormuz-related supply news and precious metals sold off after strong prior-window gains. Short-horizon breadth is weak (about 25% of assets positive over 5 sessions) but 21-session breadth remains majority-positive, so the week is mixed continuation in energy versus pullback/reversal tests in metals and cyclicals.

SPY is slightly lower after a three-day decline while crude spiked above $90, yields rose, and FedWatch priced a 66% chance of a September hike. Short-horizon breadth is weak (about 25% of assets positive over 5 sessions) against still-positive 21-session breadth, so oil continuation coexists with rate-sensitive and cyclical pullbacks rather than a single regime.

SPY is near a 52-week high with low 5-session active-return dispersion (1.92%) and only 39% of assets positive over 5 sessions after a stronger 21-session breadth. Sticky PCE/CPI, a hawkish Warsh speech, and the August jobs print on Sep 4 dominate a short holiday-shortened week; equal-weight lagged cap-weight, so mean-reversion in quality pullbacks is more plausible than chasing high-vol continuations.
CB-2026-09-01-1M official-v3-20260901-monthly monthly 2026-09-02 to 2026-10-02 SP500 100.0% Pending
SPY is near a 52-week high after an August gain while equal-weight lagged, breadth was mixed on the latest session, and the one-month window includes FOMC plus CPI/payrolls with sticky PCE and a 4.75% 10-year. Mega-cap tech still has relative strength; rate-sensitive losers lack a clear in-window easing catalyst.
CB-2026-08-30-1W official-v3-20260830-weekly weekly 2026-08-31 to 2026-09-08 SP500 100.0% Pending
Five-session active-return dispersion is only 1.62% with 40.6% of assets positive versus 73.9% over 21 sessions, SPY is 1.1% from its 52-week high, and a hawkish Chair speech plus a jobs print and Labor Day close sit inside the week, so breadth is mixed and a one-week SPY-relative edge is thin.

SPY is within 1.1% of a 52-week high after a modest weekly gain while equal-weight lagged, breadth on the 5-session window is only ~41% positive, and a hawkish Fed speech plus a mid-September FOMC with SEP sit inside the scoring window. Rate-sensitive and high-beta names face event risk; recent losers lack a clean, supported one-month reversal catalyst.

SPY is near a 52-week high with mega-cap/Nasdaq leadership (NVDA print) while a majority of S&P names fell, equal-weight lagged, and 5-session active dispersion is only 2.38%. Labor softening and the Aug payrolls print on 2026-09-04 sit inside the scoring window, so one-week edges versus SPY are mixed rather than a clean continuation or reversal regime.
CB-2026-08-27-1M official-v3-20260828-monthly monthly 2026-08-28 to 2026-09-28 SP500 100.0% Pending
SPY is near a 52-week high with mega-cap/tech leadership while equal-weight and rate-sensitive defensives lag; inflation remains elevated, the Fed is on hold with hawkish dissent, and a dense September data/FOMC calendar argues against a clean one-month continuation or reversal regime.
CB-2026-08-26-1W official-v3-20260827-weekly weekly 2026-08-27 to 2026-09-03 SP500 100.0% 0.00 pp
SPY is near a 52-week high with low 5-session dispersion (~3%) after a quiet close; Jackson Hole and mixed inflation/labor prints dominate a one-week window more than single-theme continuation. Crypto volume spikes and metals prior strength coexist with oil/defense shocks, so edges versus SPY are modest.

SPY is near a 52-week high with a small 5-session dip while 21-session breadth is still mostly positive. Rate-sensitive and quality names show deeper recent active pullbacks than mega-cap beta, while crypto and oil remain high-vol after large prior moves. Jackson Hole and the September FOMC sit inside the window, so the one-month edge is mixed rather than a clean continuation or crash-reversal tape.

SPY is near a 52-week high with modest 5-session weakness while 5s active-return dispersion is 5.10% and equal-weight led cap-weight. The slate mixes shock pullbacks in quality growth/defense/energy against stretched crypto and metals continuation, with Jackson Hole, GDP/PCE, oil inventories, and Nvidia results inside the week.

SPY is within 1.54% of its 52-week high after a modest 5-session dip while 21-session breadth is still broad. Soft July payrolls, cooling confidence, and a packed September data/FOMC calendar favor mixed mean-reversion in shocked cyclicals over chasing crypto or high-beta continuation.

SPY slipped while a majority of constituents and equal-weight beat it; 5-session active dispersion is elevated. Jackson Hole, GDP/PCE, and a large-cap semiconductor print sit inside the scoring week, so high-beta shock names can bounce or extend. Crypto already posted extreme short-window gains with very low quality scores.

SPY slipped 1.19% while equal-weight breadth was positive, rates eased slightly, and a hawkish FOMC dissent plus Jackson Hole and September FOMC sit inside the window. Cross-section is split between crypto short-horizon spikes and rate/tech shock pullbacks, so one-month outcomes are mixed rather than a clean trend or clean mean-reversion tape.

SPY is only modestly off highs after a down week while 5-session active-return dispersion is elevated; crypto already ran hard, several quality names pulled back, and the window includes GDP/PCE plus NVIDIA results, so reversal and continuation can coexist.

SPY is only 1.56% off the 52-week high after a -1.37% 5-session dip while equal-weight led slightly; VIX futures stay contained, activity surveys are firm, but the September FOMC, sticky 3.4% CPI, and Gulf oil risk keep one-month leadership mixed rather than a clean continuation or reversal tape.

SPY finished the week lower with VIX still modest at 16 while 5-session active-return dispersion is 4.38% and only about 32% of assets were positive. High-beta growth names sold off after prior strength, crypto extended a short bounce, and rates drifted higher into a data-heavy week including NVIDIA after the close on Aug 26.

SPY sold off ~2% into higher 10y yields (~4.70%), VIX 16, sticky CPI/PCE, and a September FOMC with minutes leaning hawkish if inflation stays elevated. Equal-weight beat cap-weight on the 5s/21s windows while only ~32% of assets were positive on 5s, so the month is a mixed pullback-plus-event window rather than a clean trend. High-beta tech/semis remain prior-strong but recently weak; oil strength is supply/geopolitics rather than a broad risk-on tape.

SPY is only modestly lower on the week with VIX still mid-teens, equal-weight outperforming, and 5-session active dispersion at 2.58%. Shock pullbacks in quality names sit next to stretched crypto continuation and a high-vol NVIDIA/Jackson Hole week, so the one-week pattern is mixed rather than a clean trend or crash bounce.

SPY is within about 1% of its 52-week high with VIX near 16, equal-weight outperforming, and a one-month window that includes Jackson Hole, August CPI/PPI, NVIDIA results, and the mid-September FOMC. Sticky inflation, a hawkish-leaning July minutes split, and cooling payrolls favor mixed rather than a clean continuation or reversal regime.

Five-session active-return dispersion is only 1.45% with 39% of assets positive, while SPY is modestly lower into a data-heavy week (FOMC minutes, retail, GDP second estimate). Energy/oil show short-horizon strength against a broader equity pullback; several materials/tech names show quality pullbacks rather than a single clean continuation regime.

SPY is only 1.34% off its 52-week high with low VIX after a modest 5-session dip. Soft July payrolls and housing contrast with still-elevated inflation, a 4.71%/5.28% 10y/30y curve, and a 9-3 FOMC hold with three hike dissenters. Breadth is mixed (39% positive over 5 sessions vs 73% over 21). Duration and high-beta clean-energy/EM shocks look two-sided into September CPI and the Sept 15-16 FOMC, so one-month edge versus SPY is limited.

SPY is within 1% of its 52-week high after a flat 5-session return while 5-session active-return dispersion is only 2.37%. Soft July payrolls and retail sales sit against still-elevated inflation, a hold-from-the-FOMC, and a dense in-window data/earnings calendar, so one-week outcomes look mixed rather than a clean continuation or broad reversal.

SPY is within 1% of its 52-week high after a modest 21-session gain while inflation is still above target, the FOMC is on hold with three dissenters preferring a hike, and September FOMC/CPI land inside the scoring window. Cross-section is mixed: energy and semis retain medium-horizon strength, several rate-sensitive and EM names show deep active drawdowns, and equal-weight versus cap-weight is not decisive.

SPY is near a fresh high with only 2.17% 5-session active-return dispersion, mixed labor/inflation prints, and a data-and-FOMC-minutes week. Quality international pullbacks look cleaner than high-vol continuations or EM/crypto shocks, but none have a clear one-week catalyst edge versus the benchmark.

SPY is near a fresh high with solid YTD gains while yields rose into a still-elevated inflation print, a divided FOMC hold, and a September FOMC inside the window. Breadth is mixed rather than one-way: equal-weight slightly led recently, oil and some cyclicals were strong, while duration, EM, solar, and crypto lagged. One-month edge versus SPY looks limited.

SPY is near a record with only a modest expected one-month gain. Energy, healthcare, cybersecurity, and Japan have stronger supplied continuation setups and higher bases, producing positive expected alpha versus SPY.
