Example 16.11 (January 2021)
Short interest in a US video-game retailer reached 122.97% of its float in January 2021. From an intraday low on 8 January to an intraday high of $483 on 28 January the price rose about 2 700%, then fell more than 86% by the end of the first week of February. The regulator’s staff report found that short sellers’ covering coincided with parts of the rise but was a small fraction of total buying, and concluded that positive sentiment, not buying-to-cover, sustained the rise: a squeeze was part of the story and not the whole of it.
