The 50-Day Moving Average as Support

In the last post, I addressed how the Dow-Jones Industrial Average (DJIA) failed at resistance. In cases where the DJIA is expected to fall from that level, how far can it be expected to decline? To translate this into technical analysis terms, where is the next support level? In the most recent situation, that support was at the 50-day moving average. The chart below shows this (click to enlarge).



Notice how the market moved all the way down to the 50-day moving average then "bounced" off this newly found support level. As of the time this post is being written the Dow is moving once again toward the prior resistance level.

Had the market fallen below its support at the 50-day moving average, where would it likely have fallen? Again, where are the next support levels? We should view the 50-day moving average as support level #1 (S1). Below that, the next support (S2) occurs around 10,900, then 10,700 is S3 (both of these are derived from horizontal support lines. After S3 comes the 200-day moving average at 10,600. Note, though, that the DJIA moved above support here when it was not yet overbought (the RSI never fell below 30). So, it is quite possible that we will be testing resistance once again. As I have stated in earlier posts, to determine whether resistance is likely to hold, it is necessary to evaluate what would drive profit expectations to higher levels so that resistance would be broken? Again, check the economic calendar for the upcoming week or two.

Let me finish this post by showing another way to determine likely levels of support should the market fall in coming days. This is illustrated using Fibonacci Analysis. In StockCharts.com, when you choose "Annotation," there is an icon to do this. Go from the most recent low to the recent high. The result is illustrated below (click to enlarge).


To add Fibonacci Analysis, click on the button highlighted in the upper portion of the above chart, then drag your mouse from the low value to the high (hold the mouse button until you reach the final level).

According to Fibonacci Analysis, the first likely level of support from an uptrend "retraces" 38.2% of that uptrend (this is called a Fibonacci Retracement). If that level of support fails, the next likely support occurs at 50% retracement. Finally, the last support level is at 61.8% retracement. If the market falls below 61.8% retracement, it is fairly likely that the prior low will be tested. Consult the RSI to assist you in deciding (in real time) if this is likely to occur.
