Based on the discussion that evolved from this thread, I thought I would start a new discussion about "trading" managed funds. By this, I mean not just buy-and-hold long term ... but rather buying into and out of funds as the market dictates. Does anyone currently do this ? If so - how do you determine when to sell (and when to buy) ? Has anyone developed a system that they are actively using for trading funds ? Discussion about the pros-and-cons of trading rather than buy-and-hold are welcome too. PS. I have my own thoughts and theories - but I wanted some open discussion.
