From the website of the National Association of Active Investment Managers:
NAAIM member firms who are active money managers are asked each week to provide a number which represents their overall equity exposure at the market close on a specific day of the week, currently Wednesdays. Responses can vary widely as indicated below. Responses are tallied and averaged to provide the average long (or short) position or all NAAIM managers, as a group.
Range of Responses:
Data collection issues that may affect the statistical significance of this data include:
Use of a single, composite number for each adviser may not accurately represent the market view of a manager who has short term and long term strategies that are providing conflicting signals or a manager who uses both contra-trend and trend following strategies for different portfolios.
Investment Styles very widely among managers participating in this survey. They may include managers that trade very frequently and can switch long and short positions daily. Other managers stay fully invested at all times and only change allocations among market segments or sectors. Still others trade around core positions and only a portion of their portfolios change, but that portion could potentially go from long to short very quickly.
Sample size: Although the number of participating managers, known as NAAIM Trend Setters, is steadily growing the sample size is not large and therefore may be less reflective of actual market conditions.
