a lot of idiots posting in this thread. OP i sent you a PM. For the rest of you - it all depends on what kind of fund it is. Does it rebalance once or twice a day (some rebal more)? What is the investment objective of the fund? Is there leverage involved? Is the index traded in futures contracts or derivitive units? the USO is a good example of an Index fund that everyone figured out and all the energy futures guys would destroy USO every time rolled. USO has now changed that and it's no longer an issue.
I dont understand why people in the know wouldnt expose there knowledge. For the following reasons: A. Even if its valuble info 90% here wont know what exactly to do with it. B. How many people here trade large enough to steal anyones edge? 0 C. What are the chance that everyone will use the info the same way? 0
