Take One: Catalyst for the S&P's Drop - Want to ANSWER THAT One For Me?

I had figured the S&P 500 was going to drop, I just didn't expect it to happen before it reached Monthly Resistance. However, it was at Weekly Resistance, so it's no surprise it fell. Still, what was the catalyst that made it drop? Weekly Resistance only or some other fundamental news? To be sure, I don't have any real fundamental news to really mention except that perhaps all the dropping lately has been also due to company earnings. But what company's have done so poorly that it would warrent this? I mean, our unemployment rate has dropped to the lowest levels in four years - very good news. So, yes, I've been in the process of moving to a new home, so perhaps I missed something the last few days? If I did, please fill me in if you know the answer! To my knowledge, I can't think of that many big companies failing earning reports to warrent this drop. So my conclusion is that the drop was more of a technical reason and perhaps the earnings reports were NOT all that bad, but they weren't all that good either which could mean that the technical world won the upper hand. I thought I might add my prediction of late so that you can see what I'm expecting in the next six months:

"My predictions for the S&P500 are that we will see it arrive at the Monthly Resistance this month or next and that after that time stocks will take a downturn toward Monthly Support - which should last some five or six months. Of course, this is not accounting for any catalyst that should turn the tide to break Monthly Resistance and head up to the Highs of 2007. From more of a fundamental point of view, it seems that things are going better for the U.S economy as of late. We seem to be taking a turn out of the 'mud', so to speak. So I honestly cannot tell you what the catalyst to go lower will be upon reaching Monthly Resistance."
