daily chart looks like an objective short entry with a clearly defined stop not far above.  weekly chart shows a case that CAT is likely in the early stages of a new downtrend, similar to the price action back in late 2006 until the double-top that was put in back in 2008.  however, i noticed that things seem to be playing out at a more rapid pace this time around: the trendline re-test happened a lot sooner, plus it happened at a lower level (lower high).  this trade, like most short ideas posted today, will either be stopped out soon for a small loss, could result in a decent, quick pull-back trade, or could possibly morph into a longer-term swing trade.  it will all depend on what the market does over the next week or so.
