JPMorgan: CTA Shorts Extreme but Active Fund Selling Still Dominates Treasuries
nashnova research
JPMorgan's latest report flags that CTA funds have pushed Treasury shorts to extreme levels (z-scores near -3.0), yet active managers' duration unwind dwarfs the potential CTA short-covering bid — keeping yields biased higher near term.
How crowded are CTA short positions?
JPMorgan's trend-tracking model shows U.S. Treasury futures momentum signals hit z-scores of -2.5 to -3.0 as of September 30 — deep in extreme-negative territory.
This means → CTAs — managed-futures funds that bet mechanically with the trend — have very crowded short positions, with limited room to add.
Performance confirms the buildup: CTA funds returned roughly 4.29% in September and 14.34% year-to-date; macro-quant funds returned 3.41% in September and 11.27% year-to-date.
If CTA shorts are this extreme, why haven't Treasuries bounced?
The answer is scale: active bond managers hold far more assets than CTA funds.
JPMorgan data show the 20 largest active U.S. bond mutual funds still carry duration betas — a measure of sensitivity to rate moves — at historically elevated levels, only beginning to compress in recent months.
In plain terms = active funds bet heavily on "rates will fall" and haven't finished selling. That selling flow is far larger than any buying CTAs might produce if they covered.
Can risk-parity funds fill the buying gap?
In theory, yes — JPMorgan estimates risk-parity funds' implied leverage sits below the historical average, leaving room to add bond exposure.
But rising Treasury volatility constrains risk-parity strategies, which must cap volatility exposure by design. Their buying pace is throttled, too slow to form a meaningful bid near term.
This reflects a deeper problem: when volatility itself is rising, strategies anchored to volatility get "locked out" and cannot lean against the trend.
What is JPMorgan's core call?
The central tension is not "are shorts too crowded?" — it is that extreme CTA shorts coexist with an unfinished duration unwind by active funds.
Near term, active-fund selling pressure dominates, and yields are more likely to keep rising.
But as CTA shorts accumulate further, any turn lower in yields could trigger a trend-signal reversal — forcing CTAs to cover and even flip long, amplifying a rally. When that balance breaks is the key question for the next phase.
