13F co-holder reversal spillover

Updated dailyData needs: highlong onlyshort onlylong short

In plain terms

When stocks owned by the same big funds jump or drop sharply, this one tends to move the opposite way next.

How it works

Propagates short-term reversal across the direct 13F co-ownership graph: when names co-held by the same institutions spike or slump over a short window, correlated-fund liquidity pressure on the focal name tends to reverse with a lag. The reversal direction on the 13F graph is exploratory and not separately cited.
