Overview:

The FCA's net short position disclosure requirement provides transparency into significant bearish positions in UK-listed companies. Any fund manager with a net short position exceeding 0.1% of a company's issued share capital must report it to the FCA, which publishes this data daily.

This data is valuable for several key use cases:

  • Market sentiment analysis: Tracking institutional investors' bearish views on specific stocks
  • Risk management: Identifying heavily shorted stocks that could experience volatile price movements
  • Trading strategy development: Using short interest as a factor in quantitative models
  • Competitor analysis: Understanding how peers view specific companies or sectors
  • Regulatory compliance: Ensuring adherence to position reporting requirements

API access to this data enables systematic monitoring and analysis. Key data points typically include:

  • Stock identifier (ISIN)
  • Position holder name
  • Position size (% of issued shares)
  • Position date
  • Publication date

The data's daily frequency makes it suitable for both real-time trading decisions and longer-term analysis. Historical data allows backtesting of strategies based on short interest levels or changes.

When evaluating API providers, consider:

  • Data coverage (full market vs select stocks)
  • Historical data availability
  • Update frequency and latency
  • Data quality and cleansing procedures
  • File formats and delivery methods
  • Usage restrictions and redistribution rights

The FCA's disclosure threshold is lower than many other jurisdictions (e.g., EU's 0.5%), making UK short position data particularly comprehensive for market analysis.
