Analysis of QQQ and SPY Gap Up Performance
A comprehensive analysis of the probability of QQQ and SPY closing higher after gap ups of 0.5% and 1% over the past 6 months, 1 year, and 2 years.
Aurora: Hello. Would you like to perform some financial analysis? Maybe on Target or Google?
User: In the past 6 months, if QQQ opens up 1% or more, what is the probability that it will close higher?
Aurora: ### Analysis of [QQQ](https://nexustrade.io/stock/QQQ) Gap Up Performance (Past 6 Months) Here's a detailed breakdown of how [QQQ](https://nexustrade.io/stock/QQQ) performs when it gaps up 1% or more at market open: | Metric | Value | |--------|--------| | Total Gap Up Days (≥1%) | 13 | | Days Closed Higher Than Open | 6 | | Probability of Closing Higher | 46.15% | #### Key Observations: 1. When [QQQ](https://nexustrade.io/stock/QQQ) gaps up 1% or more, it closes higher than its opening price about 46% of the time 2. Out of 13 significant gap-up days, only 6 resulted in a higher close 3. This suggests a slight tendency for mean reversion after large gap-ups #### Important Notes: - **Past Performance**: Historical patterns may not predict future behavior - **Sample Size**: The analysis covers only 13 instances over 6 months, which is a relatively small sample size - **Market Context**: Different market conditions could affect these probabilities ### Disclaimer Please remember to: 1. **Verify Data**: Double-check all numbers and calculations independently 2. **Consider Context**: Market conditions, news events, and other factors can affect trading patterns 3. **Risk Management**: Th…
User: what about the past year?

User: what about the past 2 years?
Aurora: ### Analysis of [QQQ](https://nexustrade.io/stock/QQQ) Gap Up Performance (Past 2 Years) Here's a detailed breakdown of how [QQQ](https://nexustrade.io/stock/QQQ) performs when it gaps up 1% or more at market open: | Metric | Value | |--------|--------| | Total Gap Up Days (≥1%) | 40 | | Days Closed Higher Than Open | 20 | | Probability of Closing Higher | 50.00% | | Average Gap Up Percentage | 1.61% | #### Key Observations: 1. When [QQQ](https://nexustrade.io/stock/QQQ) gaps up 1% or more, it has exactly a 50% chance of closing higher than its opening price 2. Out of 40 significant gap-up days, exactly half (20) resulted in a higher close 3. The average gap up size was 1.61%, indicating most gaps were relatively modest 4. This larger sample size (40 instances vs. 17 in one year) provides more statistical confidence #### Comparison to Previous Timeframes: - 6 months: 46.15% probability (13 instances) - 1 year: 47.06% probability (17 instances) - 2 years: 50.00% probability (40 instances) This shows remarkable consistency in the pattern, with all timeframes showing close to 50% probability. #### Important Notes: - **Statistical Significance**: The 2-year data provides a more reliab…
User: what about the past 2 years and it opens up 0.5%?
Aurora: ### Analysis of [QQQ](https://nexustrade.io/stock/QQQ) Gap Up Performance (Past 2 Years, ≥0.5% Gap) Here's a detailed breakdown of how [QQQ](https://nexustrade.io/stock/QQQ) performs when it gaps up 0.5% or more at market open: | Metric | Value | |--------|--------| | Total Gap Up Days (≥0.5%) | 115 | | Days Closed Higher Than Open | 41 | | Probability of Closing Higher | 35.65% | | Average Gap Up Size | 1.04% | #### Key Observations: 1. When [QQQ](https://nexustrade.io/stock/QQQ) gaps up 0.5% or more, it closes higher than its opening price only about 36% of the time 2. Out of 115 gap-up days, only 41 resulted in a higher close 3. The average gap up size was 1.04% #### Comparison to Previous 1% Gap Analysis: - With 1% gaps: 50.00% probability (40 instances) - With 0.5% gaps: 35.65% probability (115 instances) This is a significant finding - larger gaps (≥1%) actually have a better chance of closing higher than smaller gaps (≥0.5%). #### Important Notes: - **Larger Sample**: The 0.5% threshold provides nearly 3x more data points than the 1% threshold - **Mean Reversion**: The data suggests a stronger tendency for mean reversion with smaller gaps - **Statistical Significance**: The…
User: In the past 6 months, 1 year, and 2 years if SPY opens up 0.5% or more, what is the probability that it will close higher?
Aurora: ### Analysis of [SPY](https://nexustrade.io/stock/SPY) Gap Up Performance (Multiple Timeframes) Here's a detailed breakdown of how [SPY](https://nexustrade.io/stock/SPY) performs when it gaps up 0.5% or more at market open across different timeframes: | Timeframe | Total Gap Days | Days Closed Higher | Probability of Closing Higher | Avg Gap Size | |-----------|----------------|-------------------|------------------------------|--------------| | 6 Months | 20 | 11 | 55.00% | 0.90% | | 1 Year | 37 | 21 | 56.76% | 0.82% | | 2 Years | 81 | 45 | 55.56% | 0.85% | #### Key Observations: 1. **Remarkable Consistency**: The probability of closing higher remains remarkably stable across all timeframes (55-57%) 2. **Gap Size Consistency**: Average gap sizes are also very consistent (0.82% - 0.90%) 3. **Sample Size**: The 2-year dataset provides the most reliable sample with 81 instances 4. **Success Rate**: Across all timeframes, [SPY](https://nexustrade.io/stock/SPY) has slightly better than 50/50 odds of closing higher after a 0.5% gap up #### Interesting Patterns: 1.
