Everyone's still betting against Treasuries and borrowing costs are straining — stay short long-term bonds

Verdict: a plausible crowded-short thesis with no live signal — wait

The verdict: wait. The strongest point for the idea is the positioning evidence — per Bloomberg's October 1, 2026 piece, swelling bets against Treasuries are visibly raising repo borrowing costs, and both Lacy Hunt (Hoisington) and PIMCO's Stracke warn of further yield pressure, which fits the crowded-short regime the thesis describes. The strongest point against is that this is a watch-list setup with no validated expression: the stacked entry rules produced zero trades across all evaluated windows (up to 1,227 daily bars over 60 months), and the bounded parameter search exceeded its time budget with no robust setup established, so the published thresholds are as-is, not tuned. On the live tape, TLT closed at $77.71 with RSI (14) at 17.7 and needs to clear its Donchian (20) at $79.63 and its 50-day EMA near $81.66; BIL sits just $0.10 below its crossover levels at $91.43; TBT, at $42.47 with RSI at 77.2, is extended above its levels rather than at them. The ownership record offers no backing — the only TBT disclosure is a single reporter with 72,520 shares as of the June 30, 2026 period, a filing whose deadline had already passed, and BIL has no coverage at all; declining distributions (TBT down 27.2% annually, BIL down 14.0%) confirm falling short-term yields rather than the thesis's direction. The fact that would flip the verdict: TLT closing above both $79.63 and its 50-day EMA with the ATR (14) filter computing true would turn this from a view into a signal. Until then, the thesis is plausible but the trade is not live. Conviction breakdown: thesis support 55, trade readiness 20, risk quality 45, trigger proximity 35, fundamentals trend 40.

Trade now: no entry — the confirmations have not lined up

This is a watch-list setup, not an active signal. The rules were evaluated on real daily bars but did not open an entry, so the correct action today is to wait with exact levels in hand. The strategy waits for a trend-confirmation state on daily bars: a close crossing above both the 50-day EMA and the upper 20-day Donchian channel (plus, on the strictest version, an ATR (14) reading above 0.5, which is currently unavailable for all three tickers, and a cross below the nearest resistance level). Here is the live distance-to-trigger. **TLT** closed at $77.71 — it needs to clear its Donchian (20) at $79.63 ($1.92 away) and its 50-day EMA at $81.66 ($3.95 away); with RSI (14) at 17.7, it is far from either crossover. **BIL** is closest: at $91.43 it sits just $0.10 below its EMA (50) at $91.54 and $0.10 below its Donchian (20) at $91.53, but "near" is not "met" — no entry. **TBT** closed at $42.47, $1.90 above its Donchian (20) at $40.57 and $3.51 above its EMA (50) at $38.96, so its crossover conditions are not currently satisfiable from these levels. Risk framing once an entry does trigger: the strategy uses fixed-risk sizing at 2% per position, a hard stop at a 2% unrealized loss, a take-profit at 4% unrealized gain, an exit when a close falls below the Donchian (20) upper band after at least 90 bars held, and support/fibonacci-based exits. That makes the effective reward:risk on any triggered position roughly 2:1 by construction (4% target vs 2% stop), before slippage. Note that no robust parameter setup was established: the parameter-sensitivity evaluation exceeded its time budget and produced no recommendation, so the published thresholds should be treated as-is rather than as a tuned optimum. What "wait" means concretely: do not pre-position. Set alerts at BIL $91.53, TLT $79.63, and TBT $40.57, and check the ATR (14) filter once it computes — an entry requires all conditions of a rule set to be true simultaneously on the same daily close. Until then, the thesis (crowded shorts against long Treasuries, per the idea's own argument, with PIMCO and Hoisington cited as warning of further yield pressure) is a view, not a signal.

Crowded shorts, strained funding, and two heavyweight bears: the short-duration case holds together

The core of this idea is a positioning argument, and the cited tape supports it. Per the Bloomberg piece from October 1, 2026, swelling bets against Treasuries are fueling repo borrowing costs — exactly the funding-market strain the thesis points to as evidence that short pressure has not yet released. When short crowding starts to cost real money in funding markets, either the crowd covers (yield spike) or the strain resolves violently; the thesis reads that as more downside for long duration, which is the direction this idea takes. The valuation leg matters because it neutralizes the most common objection. The usual reason to fade a bond bear market is that after a multi-decade yield spike, a bounce is 'due.' The October 1 Bloomberg analysis argues the opposite: Treasuries are not yet cheap on their own history, so the mean-reversion floor the bounce-traders rely on may not exist. If there is no historical valuation support, the crowded-short regime can extend further than skeptics expect. The smart-money leg adds credibility. Per Bloomberg's October 1 interview, Lacy Hunt at Hoisington sees risk of a Fed policy mistake and persistent inflation pressure, and PIMCO's Stracke warned on October 2 of a yield shock ahead. When two of the largest, most established fixed-income shops independently flag more yield pressure,…
