Analysis of 47,458 open-market insider purchases from 2020–2025 shows that insider buying does not reliably predict future outperformance, with larger purchases often performing worse than smaller ones.
I went through 47,458 insider buys. The biggest ones were actually the worst.
Retail investors often use insider buying as a high-conviction signal; this data suggests it is better used as a starting point for fundamental research rather than a standalone buy signal.
Watch Future studies adjusting for risk and longer time horizons to see if the underperformance persists.

Market participants are warning that August 21, 2026, is an Options Expiration (OPEX) day, where market makers are expected to pin prices near 'max pain' levels, increasing the risk of 0DTE options expiring worthless.
Just a tip because I genuinely don't like to see you tards losing money. Tommorow is OPEX day.
High volatility and pinning behavior can lead to significant losses for retail traders using short-term directional bets.

A quantitative study of 111,129 touches across 18 years of NQ and Gold data found that while bounce probability drops after the first retest, it stabilizes thereafter, contradicting the common trading adage that every touch weakens a level.
in this sample, the fifth touch was no less likely to bounce than the second.
This challenges common technical analysis assumptions used in retail trading strategies, suggesting that 'level-fading' strategies may not have the edge traders expect.
Watch Future backtesting of technical indicators against randomized control datasets to verify if other 'common knowledge' patterns are statistically significant.
