HTZ spent six weeks quietly covering — and then reversed sharply, with short interest jumping 13% in a single week to reclaim 18.5% of the free float, just as the borrow market opened up more than it has in months.
That reversal is the week's defining tension. The previous note, published eight days ago, described an orderly covering trend that had pulled short interest down from a peak above 49% of float in mid-April to just under 40%. Those figures and the current 18.5% reading reflect a significant data update — the earlier note was working from a period when the free float denominator produced a much higher percentage. What is unambiguous is the directional shift: short interest bottomed around mid-May near 51 million shares, drifted sideways through late May, then jumped to 57.5 million shares by June 11 — a 13% weekly rise. Days to cover, per the FINRA settlement figure, stood at 8.1 days, meaning any forced unwind would take well over a week to clear at normal volumes. The ORTEX short score has crept to 74.9, its highest reading in the recent history window, pointing toward elevated short-side conviction.
The borrow picture tells a different story from last week's near-frozen market. Availability has swung dramatically — from just 1.1% on June 5, when the lending pool was essentially closed, to 14.2% now. That is a sixfold loosening in less than a week, and it explains how shorts managed to rebuild positions so quickly. New borrows were simply available. The cost to borrow, meanwhile, has dropped sharply — down 11% on the week and 60% from a month ago, falling to 1.17% from levels above 4% in early May. Cheap, more available stock to borrow directly enables short rebuilding. The 52-week availability low touched near zero just weeks ago; the current loosening represents a structural shift in the borrow market dynamic, even if 14% availability still leaves the lending pool well short of comfortable.
Options traders are not particularly animated by any of this. The put/call ratio at 2.20 sits almost exactly on its 20-day average — essentially flat, with a z-score indistinguishable from zero. That PCR level is structurally elevated relative to the 52-week low of 1.17, but it has been running in this range since mid-May and reflects a steady, baseline defensive tilt rather than any fresh escalation. The Street is similarly unmoved. The most recent analyst action came from Susquehanna in early May, lifting the target modestly to $5.50 while holding a Neutral rating. Morgan Stanley sits at Equal-Weight with a $5.00 target. With the consensus mean around $4.64 against a current price of $5.13, the Street is broadly neutral-to-skeptical — the stock is already trading above the average target. BofA's Underperform rating with a $2.70 target is the outlier bear case, anchored to concerns about Hertz's balance sheet and fleet depreciation drag. The EV/EBITDA multiple at 44x reflects just how demanding the valuation remains for a company posting negative earnings, and the ORTEX short-score rank in the 4th percentile — meaning nearly every other stock scores lower on short-side pressure — underlines how structurally crowded the bear camp remains.
Ownership adds an important structural wrinkle. Knighthead Capital, the restructuring-focused manager that emerged from Hertz's bankruptcy, holds 57.5% of shares outstanding. That concentration means a very thin effective float. Pershing Square holds another 4.8%. With insiders having sold consistently — the CEO sold $1.3 million of stock in April, the COO followed in May — there is no internal buying to counterbalance the institutional weight of the short book.
The next earnings event is scheduled for August 6. The most recent print, in early May, sent the stock down 6.6% on the day and 10% over the following week. The one before that, in late May, produced a 2.7% gain on day one but gave it back within five days. With short interest now rebuilding into a tightening availability window, the August print — and any commentary on fleet costs, EV strategy, or booking trends — is the obvious next flashpoint to watch.
