tl;dr: It's a max of 0.3% of GME shorted through XRT based on given numbers.
There's been talk of shorting GME through XRT for years and more of it recently. My question was how much of GME could be shorted through XRT. This is how I calculated it:
https://www.etfchannel.com/symbol/xrt/ Shares Short: 23,670,000 % of shares short: 340.58% XRT Price as of close Oct 3 59.22 Value of shorted shares: 59.22 * 23,670,000 = 1,401,737,400 ($1.4B) https://www.ssga.com/us/en/intermediary/etfs/funds/spdr-sp-retail-etf-xrt GME Constituent %: 1.252375 Shares: 262841.000 Potential value of shorted GME 1,401,737,400 * 0.01252375 = 17,555,008.7633 ($17.5M) GME Market cap close Oct 3: $4.457B Potential % share GME via XRT: 17.5M/4457M = 0.003926 (0.39% of GME)
As an aside, yahoo currently reports for GME:
Short % of Float (Sep 15, 2023): 20.11% Short % of Shares Outstanding (Sep 15, 2023): 17.67%
XRT shorting seems fairly inconsequential to me but maybe there's another 30 ETFs somewhere being utilized in this way.
