Friday's action (especially when combined with Thursdays) has characteristics of either a kick-off move or an exhaustive move (gap opens followed by big moves on big volume). If this was the kick-off to the next leg of the rally from the June low, there is an argument that the mid-point of the rally may lurk somewhere between Thursday's low and Friday's high. This means new highs coming, and perhaps by a considerable margin. If this was an exhaustive move, indices should rollover soon (like tomorrow) and Friday's move (not necessarily Thursdays) should be fully retraced sometime this week. [With some imagination, it may be conceivable that Thursday was a kick-off and Friday was exhaustive, but I don't want to over analyze.]
Warning: next comments probably biased by me being on the wrong side of the market last week...
Technically, things look quite bullish, but I remain open to a downturn in the days ahead. Why? 1) Technically, things were quite bearish only last Monday. The recent pattern has been swings back and forth. So, if the pattern continues, the next swing down may not be far away. This rally so far is not a trend. 2) To use Elliott Wave language, the move from the June low has seemed corrective rather than impulsive. We are now into a fourth push up (usually only two or three) and there is still a fair bit of distance to get back to the May 1 high. I don't do counts, but I understand that lots of zig zagging with limited progress are the template of corrective patterns. So, while Thurs/Fri may be the start of a break up and out, the rally to this point doesn't have a very bullish character. 3) My sense is that more defensive sectors have been leading in the rally (though Thurs/Fri may have changed that somewhat). I would like to see more aggressive sectors get moving. Perhaps Al Dente's Russell chart is signalling that those horses are about to go. 4) Lastly, the Thurs/Fri move lacked breadth. The MO is up but only moderately given the price move, and the ARMs index plunged. The Russell accelerating would clear this. However, if the market doesn't sell off tomorrow and if breadth doesn't pick up significantly, I'll have an ARMs sell warning will go into effect for the rest of the week.
