Hi guys. Here's the gist: I'm a longer-term swing trader. I've noticed that extremes in the Commercial Long to Comm. Short and Comm. Long to total OI indicators have an uncanny ability to act as leading indicators for trend reversals in commodities. Anyhow, I want to see if I can translate this idea--substituting institutions for commercials--to more accurately find the general bottoming area of the typical 1-3 month decline along the long-term trend of a stock. What I need is a source that has the historical change in institutional ownership % levels over the past 1 year+. Thanks for reading.
