总结

本研究探讨为何短期趋势跟随收益自 2009 前后开始减弱。研究分析了 1995–2025 年间一组流动性较高的期货合约以及一个 CTA 代理指标，并按信号速度和资产类别比较结果。研究评估了策略容量、电子交易、CTA 与订单流互动的变化，以及一种市场微观结构解释。

研究报告的关键区别在于经波动率标准化的最小变动价位：2008 之后，小变动价位合约在各个信号周期上的趋势表现均有所恶化，而大变动价位合约大体保持原有表现。作者通过一种反馈机制解释这一模式：趋势交易会强化触发交易的价格走势；他们认为，高频做市商对可预测订单流的响应，在稀疏的小变动价位订单簿中扰乱了这一机制。这是对观测模式的实证解释；本文并未证实该机制会持续，也未证明研究发现能推广到所研究合约和时期之外。

核心观点

  • 研究报告称，短期趋势跟随表现自 2009 前后开始下滑。
  • 研究按信号周期和资产类别比较期货合约，并评估了若干种可能的解释。
  • 经波动率标准化的最小变动价位，可区分趋势收益减弱与大体保持稳定的合约。
  • 作者提出，趋势交易可能通过市场冲击强化价格走势。
  • 作者将小变动价位合约表现下滑归因于做市商行为变化，以及对这一反馈循环的支撑减弱。

# Is Trend Still Your Friend?: A Microstructural Account of the Demise of Short-Term Trend-Following


# Is Trend Still Your Friend?: A Microstructural Account of the Demise of Short-Term Trend-Following









Systematic trend following has, on average, been profitable for at least two centuries; yet since approximately 2009, short-term trends have ceased to deliver reliable returns. Using a cross-section of roughly 100 liquid futures contracts spanning 1995-2025, together with an industry-representative CTA proxy, we document the break and characterise its dependence on signal speed and asset class. We evaluate four candidate explanations - capacity constraints, market electronification, a regime change in CTA-versus-order-flow interactions, and a microstructural mechanism - and find that the first three fail on grounds of timing, magnitude, or cross-sectional heterogeneity. Our central empirical finding is that the cross-sectional variable distinguishing degraded from surviving trends is the volatility-normalised tick size: post-2008 trend PnL has collapsed on small-tick contracts across all signal horizons, while remaining essentially intact on large-tick ones. Neither asset class nor liquidity replicates this dichotomy. We interpret this result through a self-fulfilling feedback loop that, in our view, lies at the heart of the trend anomaly itself: trend signals trigger directional trades, whose market impact reinforces the very price moves that generated the signal. Both the profitability and the persistence of trend are sustained by this impact channel, which requires that trend followers can execute aggressively at reasonable cost. We argue that the post-crisis transition to HFT-dominated market making, whose liquidity-withdrawal behaviour in front of predictable directional flow has sharply contrasting consequences for sparse (small-tick) and dense (large-tick) limit order books, has broken this loop on small-tick contracts. On large-tick contracts, residual depth remains sufficient, and the loop continues to operate.
