u/marktrain1234 went crazy on Reddit analyzing $GRPN ‘s short interest.
Note: this started off as a trade for me. I’m in it for the fundamentals now. I did a lot of work and found more and more to like about the actual business and what it could be.
Nevertheless, read this weaponized autism:
GRPN: 45% locked, 65% short of float, 156% borrow utilization.
Float is broken.
Continental General filed a 13G/A showing 3,620,590 shares, or 9.24%, up from 2,929,832 prior. Another ~691K shares just moved into long-term hands.
Ortex live shows shorts added 631K shares today: 727K borrowed, only 96K returned.
Net new shorting. No covering.
Live SI is now 13.87M shares per Ortex, or 57.25% of free float.
I rebuilt the ownership stack from Ortex’s holder list and cross-checked it against 13D, 13G, 13F, and Form 4 filings.
Shares outstanding: 39.19M
Treasury: 12.24M separate, not in S/O
Ownership stack:
Locked holders: 17.72M, 45.2%
Linmar, likely locked/concentrated: 1.65M, 4.2%
Index/ETF: 7.82M, ~5.6M loanable
Prime broker custody: 4.31M, ~1.1M adjusted loanable
Market makers: 435K, ~304K loanable
Pod-shop HFs: 4.81M, ~572K loanable
Concentrated long HFs: 3.06M, ~269K loanable
Mutual funds: 834K, ~542K loanable
Asset managers: 1.52M, ~672K loanable
Pensions: 208K, ~134K loanable
Central bank: 52K, 0 loanable
Total identified: 42.41M shares
Prime broker double-count adjustment: -2.58M
Adjusted identified: 39.82M
Shares outstanding: 39.19M
Implied retail: basically zero.
The locked column is the key:
Pale Fire: 10.18M
Continental / Gorzynski: 3.62M
Windward: 1.94M
CEO direct: 1.14M
Insiders/officers/directors: ~840K
Locked total: 17.72M shares, or 45.2% of S/O.
Add Linmar and locked/concentrated ownership may be closer to 49.4%.
The pod shops hold another ~4.81M shares: Millennium, D.E. Shaw, Citadel, Two Sigma, Squarepoint, ExodusPoint, Point72, Verition, Balyasny, Renaissance, Schonfeld, Brevan Howard, Walleye, AQR, Centiva, etc.
These are not clean passive lenders. These are market-neutral platforms. If they own GRPN, it may be paired against shorts or embedded in books where lending the long defeats the trade structure.
Concentrated long HFs hold another ~3.06M shares. Again, not clean passive lend.
The real lenders are index/ETF holders:
BlackRock: 2.94M
Vanguard: 2.10M
State Street: 881K
Geode: 654K
Dimensional: 453K
Schwab: 230K
Northern Trust: 213K
Pacer: 203K
First Trust: 110K
Rhumbline: 31K
Index subtotal: 7.82M shares
Estimated loanable: ~5.6M
Total estimated loanable supply:
Index/ETF: 5.6M
Prime broker adjusted: 1.1M
Hedge funds: 0.8M
Mutual funds: 0.5M
Asset managers: 0.7M
Pensions: 0.1M
Market makers: 0.3M
Retail residual: ~0
Total: ~8.9M shares.
Ortex live SI: 13.87M
Estimated loanable: ~8.9M
Excess over loanable: ~5.0M
Utilization: 156%
The math does not work.
Either real SI is lower than Ortex shows, which today’s +631K borrowed argues against; real SI is higher and hidden in swaps/TRS/ETF baskets; or my loanable estimate is too conservative.
My best guess: real economic short exposure is 14M–19M shares including synthetic/swap exposure.
Against a true tradeable float of roughly 19.8M shares, that is 70–95% short of true float.
TLDR:
GRPN’s tradeable float is a lie.
45% is straight locked. Add Linmar and it may be closer to 50%. Pod shops hold another multi-million-share block that likely is not clean borrow. Index funds and pensions are the only real lenders, and they max out around 9M shares of capacity by my math.
Short interest is 13.87M per Ortex.
Short interest exceeds estimated lendable supply by ~5M shares.
Continental locked up another 691K shares and shorts added 631K on the same day.
Both sides are pressing.
I think this is one of the tightest setups since pre-squeeze CAR.
But I am one guy with a spreadsheet and Ortex screenshots, so tell me what I’m missing.
Not advice.
Long Groupon. Game on.
