#86 crowded_long_unwind — mirror of short_squeeze on the long side; Lou-Polk 2020 'crowdedness'.

In plain terms

When 13F filer concentration is at multi-year highs AND price is rolling over with vol expansion, expect forced-deleveraging cascade. Mirror of squeeze.

How it works

Heavy institutional ownership (top 5% n_filers in 13F) + recent vol expansion + negative price trend + crowded sector → setup for forced-deleveraging unwind. Mirror image of short-squeeze: too many longs holding the bag, first selloff cascades. Short signal.
