# Compare stocks

`GET /reddit/stocks/v1/compare`

Compare up to 10 stock or ETF tickers side by side over the same UTC calendar-day period.

Results are sorted by `buzz_score` descending and return the same core analytics used by
`/trending`: `buzz_score`, `trend`, `trend_history`, `mentions`, `unique_posts`,
`subreddit_count`, `sentiment_score`, `bullish_pct`, `bearish_pct` and `total_upvotes`.
`trend` is activity momentum over the current 3 UTC days vs previous 3 UTC days using mentions, upvotes and subreddit breadth; not price movement. For `from`/`to`, anchors at `to` (or now when `to` is today).

If a requested ticker is supported but has no qualifying data in the period, it is still returned with zeroed metrics.

`mentions` includes inherited thread-context mentions. Use raw `/mentions` without
`include_inherited` for explicit-only rows.

## Query parameters

- `from` string, date, nullable — Start date in YYYY-MM-DD. Inclusive UTC date.
- `to` string, date, nullable — End date in YYYY-MM-DD. Inclusive UTC date. Omit to use the current UTC date.
- `days` integer — Deprecated v1 compatibility shorthand. Prefer `from` and `to` for reproducible UTC date windows.
- `tickers` string, required — Comma-separated list of ticker symbols (e.g., TSLA,NVDA,AMD)
