TLT bears rebuild as the short-covering rally stalls

TLT has reversed course from last week's covering rally, with short interest ticking back up and the fund slipping 0.6% on the week to $81.11.

The previous note documented bears retreating sharply, with short interest falling from a peak near 127 million shares to around 106 million. That decline has now partially unwound. Short interest climbed 1.1% over the past week to 108.6 million shares, equal to 19.5% of free float. That is still below the mid-October peak, but the direction has flipped. Bears who covered through late October appear to be re-establishing positions, consistent with the fund giving back its gains. TLT is down 0.76% on the day and has retraced roughly a third of its prior-month advance. The monthly gain remains 4.7%, so the broader trend has not broken, but momentum has clearly slowed.

The borrow market remains relaxed, which matters for understanding the nature of this short rebuilding. Availability is at 212%, meaning there are roughly two shares available to borrow for every one already lent out. That is tighter than the 294% reading from last week, with availability falling nearly 28% over the past seven days, but it remains well above the stress zone. The 52-week tightest point was 78% availability, reached on October 16. Cost to borrow has drifted lower too, now at 0.35%, down 24% over the past month. Cheap, available borrows make it easy for new short sellers to enter without squeezing existing positions. The ORTEX short score sits at 64.6, little changed over the past week, reflecting an elevated but stable bearish posture.

Options positioning offers a mild tilt toward caution. The put/call ratio is 0.51, slightly above its 20-day average of 0.50 and around 0.86 standard deviations above that mean. The 52-week range runs from 0.47 to 0.81, so the current reading sits near the low end rather than signalling any notable defensive build-up. Options traders are not adding meaningful protection here, which makes the short interest rebuild the cleaner signal.

On the ownership side, the institutional register is worth a brief look. Managed Account Advisors holds 8.6% of shares, while Northwestern Mutual trimmed its position by 5.4 million shares in the June quarter, cutting to 7.8% of shares. Bank of America made the most dramatic move, reducing its holding by over 21 million shares to roughly 3.97% of shares outstanding. Those are June-quarter figures, so the impact on today's supply/demand dynamics is indirect, but the pattern suggests larger institutional holders have been net sellers of long-duration duration exposure through mid-year.

The monthly income stream from TLT remains consistent, with October's distribution at $0.343 per share, the highest in the past five months, reflecting the still-elevated yield environment that simultaneously draws income-seeking buyers and macro-bearish short sellers into the same instrument.

The key tension to watch is whether short interest continues to rebuild toward the October 16 peak near 127 million shares, or whether the fund's resilient monthly performance draws another round of covering before bears can press the position further.
