Mention Volume + Anomaly Bandsi
How anomalies are detected

A 30-day rolling mean and standard deviation of daily mention counts are calculated. A day is flagged as an anomaly when its mention count exceeds the mean + 2 standard deviations (the upper band).

The shaded region shows the 2σ band — mentions within this range are considered normal activity.

Retail Subreddit Chatter
Daily ticker-mention volume across retail subreddits. Sourced from youyanggu/yolostocks-data CSVs for 2021-2025 and yolostocks.live's rolling 100-day feed for 2026 onward. Apples-to-apples across the full window: every metric uses the daily top-20 tickers by mentions, since the github CSVs only carry ~top-N per subreddit. Aggregate mentions = sum of top-20. Top-10 concentration = top-10 / top-20 share — high means a few names dominate (GME-2021, AMC-2021, BBBY-2022); low means chatter is spread out. Top-10 churn counts how many of today's top-10 weren't in yesterday's top-10.
