Click up to four bubbles to compare their short-interest components side by side.
Read this before using the map.
FINRA covers US listings only, so non-US names are not plotted.
FINRA short interest is published twice a month and is roughly eight business days late.
It is an open position, not a daily trade. Daily short volume is off-exchange only
and is inflated by market-maker hedging, so read its trend rather than its level. Borrow
fee, utilization and cost-to-borrow are not available here: this is a short-crowding map,
not a probability of a squeeze. Some percentages use shares outstanding when Yahoo's float
is missing or implausible; hover a point to see which denominator was used.
