It is highly contested whether or not the daily RegSHO reports that a security has been "shorted", as having a short position, or if it is just a type of reporting requirement for market making activities. It is both. Transactions that have shares marked as "short" can very well be an investor selling a short position or a market maker allocating shares in order to provide liquidity but not in their possession
