I've detailed some potential resistance points in the past few months on SPY (such as her on July 30th). Call it luck, but the market has bounced off the 50% retracement level and the top of the gap formed in October 2008.
A move through those levels would be a bullish sign, while a close below the 50-day simple moving average (see bottom chart) would indicate that the intermediate bull run is over. However, from a technical perspective, we are still in a bull run until the 200-day SMA (or 40-week) is breached. Volume picked up this week on the down days, which could potentially be a sign of things to come.
The first chart is weekly with Fibonacci, the second a daily chart with a resistance line at the top of the gap and a trend line (which we breached Friday, although I am writing this an hour before the market closes):

I think it's time someone poked a few holes in the idea of using moving averages as potential support or resistance levels.
A 50 day moving average is no more of a support or resistance level than a 2 day moving average. Since a moving average is only a mathematically interesting line that is a "derivative" of price history, it has absolutely no value as a predictor... other than the reality that some investors believe in it. In that respect, if price action drops down on top of a popular moving average such as the 50 day, and then bounces, it can indeed stir up investor confidence. In reality though, this is nothing more than a fluke.
For example, a lot of noise is being made that almost all indices have recently fallen slightly through their 50 day, the popular line of thinking being that the "next stop" is the 200 day. But the point could be made (and this is the truth) that while the S&P just passed through its 50 day, it also passed through its own 300 day, on the way toward the 200 day. Where's the sense in waiting to see if the 200 day will "hold", when the 300 day has already been breached?
There's no magic in moving averages as support or resistance levels, but I along with every other investor, do appreciate that they provide a smoother visual of what's happening. But do they actually offer support or resistance? Not in the slightest! Try using a 113 day moving average (pick any number you like) and you'll see that in reality it's just as meaningless as the 200 day.
The real value in MAs is that they can be used to formulate some truly meaningful data such as % of stocks above the 50 day. Now that means something.
You might ask, "why did you post this?", and the answer would be "because I'm bored this morning".

Some time back, I posed the thought (actually, a question) that the only reason the 200 day (S)MA was significant was because folks believed it to be so.
My follow on was that I felt that was one of the reasons contrarians often did so well. When they saw the lemmings respond to these "artificial" signals and the contrarians were looking at more significant things that told the true story, all they had to do was position themselves for the certain-to-come reversal.
Now that I've learned a little more, I'm aware of "sell-siders" and "buy-siders" and it makes more sense. Everbody has to eat and feed their family.
