Amazon's 10% post-earnings surge is a direct signal that investors are breathing a sigh of relief over the company's AI spending plans. While other tech giants have faced skepticism about their massive AI costs, Amazon's CEO successfully sold Wall Street

Verdict: wait for confirmation — strong fundamentals, no signal yet

Amazon's post-earnings bull case is genuinely strong on paper: $716.9B in revenue growing 12.4% year-over-year, a 50.3% gross margin in the 78th percentile of its sector, and diluted EPS up nearly 30% to $7.17. Per the CNBC piece on CEO Andy Jassy's commentary, the roughly 10% gap-up signals institutional relief that Amazon's $131.8B in annual capex will drive returns rather than destroy value. The single strongest point against the trade, however, is that the six-condition entry strategy never fired once across 1,785 evaluated daily bars spanning 60 months — this is a watch-list configuration, not an active signal. Three of six conditions are live today (price below the Bollinger upper at $238, price below the 20-day EMA at $236, and Stochastic at 24.0), but the reversal has not started: the Stochastic %K-over-%D cross has not occurred, price has not reclaimed the EMA, and OBV has not crossed above the Bollinger middle band. No robust parameter setup was established from the sensitivity analysis, so there is no optimized variant to lean on. With three conditions still unconfirmed and a 2.5% stop that leaves little room for adverse moves, the disciplined response is to wait. **Conviction Breakdown** - **Thesis Support: 68** — Strong revenue, margin, and EPS growth directly support the post-earnings momentum narrative. - **Trade Readiness: 25** — The rules have produced zero triggers in five years and three of six conditions remain unconfirmed. - **Risk Quality: 40** — A 2:1 reward-to-risk ratio is sound in theory, but a 2.5% stop is unforgiving near a $232 support floor. - **Trigger Proximity: 35** — Three conditions are met and the %K/%D values are tied at 24.0, but no crossover has occurred and OBV status is unknown. - **Fundamentals Trend: 78** — Top-tier peer percentiles in free cash flow (100th), operating margin (82nd), and gross margin (78th) underpin the long-term thesis.

AMZN closed at $235.50, sitting just below the 20-day exponential moving average at $235.72 and the Bollinger Band upper at $238.27 — two of the six entry conditions are already satisfied. The Stochastic (14) at 24.0 is at or below the 30 threshold the setup requires, so a third condition is met. What the strategy still needs is a genuine reversal turn: the Stochastic %K must cross above its %D line (currently near — no cross yet), price must cross back above the 20-day EMA, and on-balance volume must cross above the Bollinger middle band. If all conditions align, the exit architecture is tight. The hard stop fires at a 2.5% loss from entry, which at today's close of $235.50 sits near $229.60. The nearest support level at $233.83 is close to the current price, so the support-based stop at $232.24 acts as the first protective line. On the upside, the take-profit target is a 5.0% gain from entry, near $247.30, and a secondary resistance-based exit exists at $235.09 — meaningfully close to current price and worth watching. That produces an effective reward-to-risk ratio of roughly 2:1 (5.0% target versus 2.5% stop), with a 45-bar time stop as the backstop. Because no robust parameter setup was established — the parameter-sensitivity evaluation exceeded its time budget — readers should treat the default thresholds as published without a nearby-variant recommendation. "Wait" means concretely: keep AMZN on the daily watch list and let the strategy trigger only when the Stochastic cross, the price-over-EMA cross, and the OBV cross all fire. The rules were evaluated across 1,785 daily bars over five years without opening an entry,…
