On this chart, I have calculated the % difference between the 3 & 9 EMA's as a way to view the loss of upside momentum. I explained most of how and why I've done it this way in a chart I put up at the end of February: The key is not the % difference itself as there is no absolute number that becomes a red flag but the change in the percentage.
Besides the apparent loss of momentum in $SPX , we also have negative divergence in the and, unless $SPX rallies into the end of the month, then we also have what Welles Wilder calls a top failure swing in the . This occurs when the dips below the previous trough low of the , which occurred in January. As of Friday, April 11th, $SPX was off 56pts on the month and for the failure swing in the to be confirmed, $SPX will have to close out the month somewhere around there.
Next, we have negative divergence in the along with the fact that the is below +100, a further sign of weakness.
Finally there is a potential cross of the 20/20 sto in the works. If we do close out the month in the red, the sto cross might not come until the end of May and would serve as further confirmation that we are headed into a decline of several months.
Why is this important? Because the current monthly chart of $SPX shares several similarities of the monthly charts from the 2000 & 2007 tops, which you can see at the links below. History need not repeat but it's always wise to be aware of the fact that it might.
