Trend-following funds increase equity shorts as markets face higher volatility

Trend-following strategies, including commodity trading advisors (CTAs), have been accumulating short positions in global equities after a period of unwinding, reflecting growing caution among systematic investors. These funds are also reducing holdings in U.S. Treasurys and increasing long exposure to the U.S. dollar. The repositioning is driven by price momentum and has been reinforced by geopolitical tensions, rising oil prices and unclear Federal Reserve policy prospects, which together may amplify market moves in either direction.

Key Points

  • Trend-following funds, including CTAs, have been building short positions in global equities after a period of unwinding - impacts equity markets and investor risk sentiment.
  • These managers are reducing exposure to U.S. Treasurys while adding long U.S. dollar positions, indicating a more defensive cross-asset stance - impacts fixed income and currency markets.
  • Flows are largely mechanical and driven by price trends, which can amplify market moves and lead to either additional selling pressure or rapid rebounds depending on momentum.

Trend-following strategies run by systematic managers are moving toward a more defensive posture, with a notable build-up of short positions in equities, according to a new analysis from Bank of America. The shift highlights a rise in caution among investors who follow price momentum rather than fundamental company metrics.

Commodity trading advisors, or CTAs, have steadily increased bearish bets on global equities after previously reducing such positions. That repositioning has come as markets have struggled to establish a clear direction amid heightened volatility and lingering macro uncertainty.

The reallocation is not limited to equities. Trend followers have been cutting exposure to U.S. Treasurys while adding to long positions in the U.S. dollar. Analysts characterize these moves as largely mechanical - responses to evolving price trends rather than the result of discretionary forecasts - but note that mechanically driven flows can nonetheless magnify market moves.

Several developments have contributed to the recent price dynamics. Escalation in the Middle East conflict and interruptions to energy and shipping routes have been cited as sources of downside risk for risk assets. In particular, oil price increases and disruptions to traffic through the Strait of Hormuz have raised concerns about their potential effects on global growth and inflation. Historically, such shocks tend to weigh on risk-sensitive assets and favor defensive trades like a stronger dollar.

At the same time, uncertainty over the Federal Reserve's future policy path remains a central influence on market positioning. Persistent inflationary pressures coupled with higher energy costs could postpone interest rate reductions, keeping financial conditions relatively tight for longer. That backdrop has made it more difficult for equities to sustain rallies and has encouraged momentum-based funds to tilt toward short positions.

Analysts stress that CTAs still have scope to increase their short exposure to equities if downward momentum continues. That implies a possibility of additional selling pressure in markets in the near term, particularly should macroeconomic conditions worsen or volatility spike again. Conversely, the same momentum-driven framework means that if sentiment reverses or key risks abate, those managers could be forced to cover shorts rapidly, potentially sparking a sharp rebound.

The evolving positioning by trend followers underlines how mechanical, price-based strategies can contribute to larger market moves in both directions when combined with geopolitical developments, commodity market shifts, and policy uncertainty.

Risks

  • Further macro deterioration or heightened volatility could prompt CTAs to add more equity shorts, increasing downside pressure on equity markets - particularly sectors sensitive to economic growth.
  • Escalations in geopolitics and energy market disruptions, including higher oil prices and shipping interruptions, pose inflation and growth risks that could weigh on risk assets and affect energy and shipping-linked sectors.
  • Persistent inflation and higher energy costs may delay Fed rate cuts, keeping financial conditions tight and making it harder for equities to sustain rallies - this affects interest-rate sensitive sectors and fixed income markets.
