After the three day weekend investors may have had too much time to worry, the stock market had another big down day, with the Dow closing down about 100 points. Bend financial advisor Bill Valentine says the sell-off is a continuation of what started in early August, on concerns of the U.S. economy and big problems in Europe.  Looking forward, Valentine doesn't think the President's speech on jobs this Thursday will move the market much: “We know what he's going to say and I don't expect it to have any effect on the market or frankly on the economy, but it is important to note that we are still way ahead of where we were in August. We had a big fall in early August, then a quiet recovery, then another big fall.” Valentine does not believe at this time that we are headed towards a double dip recession.
