Full fails-to-deliver settlement history for one ticker, ascending by settlement date. Each record carries the date, failed-share quantity, prior-day closing price (may be null), CUSIP, and security description. A fail-to-deliver (FTD) is a settlement fail: the seller did not deliver the shares to the buyer by the settlement date. Persistent or spiking fails for a ticker are read as a short-squeeze / settlement-risk signal. Note the pre/post 2008-09-16 threshold discontinuity: before that date the SEC published only fail balances of 10,000 shares or more, so early history undercounts smaller fails and is not directly comparable with the later full series.
