Friday’s modest leap narrowly missed our still-interesting trendline, which came in at around 28,661.  Because it is rising with a slope of about 12 points per day, we should look for resistance on Monday at 28,673, moving up to 28,721 by week’s end. If and when it is hit, plan on buying some cheap DIA puts with about two weeks left on them. Be ready to jump on it if this happens on the opening bar. Otherwise, I’d suggest waiting till the close for a better deal. It will always be highly speculative to bet against a bull market that has been chugging  along for more than a decade, so don’t overdo it. This is just to have a horse in the race. ______ UPDATE (Dec 23, 6:05 p.m.): The trendline comes in Tuesday at around 28,705, as near as I can make it.  My gut feeling is that the Indoos will get within 10-15 points of this ‘hidden resistance’ before feeling its downforce. If you are keen on getting short, the instruction above still applies. ______ ‘UPDATE (Dec 26, 12:30 a.m.): For Thursday, I estimate the trendline will be at 28,712. The trading guidance given above remains viable. Last week’s 28,608 high got close enough to the line that we should be open to the possibility that the anticipated top has already occurred. _______ UPDATE (Dec 26, 5:14 p.m.):  Use 28,721 for Friday. If it’s hit, don’t be surprised if this occurs four seconds before the closing bell. Buy a few puts anyway — what could possibly could go wrong over the weekend?
