HQ's 32% drop came from index arbitrageurs selling on incorrect data that has since been corrected, leaving them to decide what to do with the shares they sold. The QTUM ETF, which owns 6,565,887 HQ shares, most of the float, published weighting changes against its semi-annual review rules, implying ~3M shares to sell. After conversations, the index provider reversed this, keeping weightings except minor pro-rata changes for QNT's entry. Short sellers face a 101% overnight borrow rate. x.com x.com
