Una interessante analisi tecnica/statistica del mercato che va contro la mia posizione.....

Soon after today's FOMC announcement, at approximately 2:25pm ET, the NYSE advance/decline ratio hit 3:1 positive territory for the first time (see chart on our intraday snapshot page.) That bullish action triggered the intraday buy signal recently discussed in my March 19th column. From 2:25 ET until the close, the S&P500 rallied from 1423 to 1434, producing another solid profit for this intraday setup.
Over 250 issues made new 52-week highs during Tuesday's session and breadth was better than 4:1 positive. That's the third consecutive day we've seen advancing issues more than double decliners, a sign of broad-based strength. Clearly, the S&P is following the lead of the cumulative breadth line, which already closed in new highs for the year on Tuesday.
From an intermediate-term perspective, today's lopsided breadth statistics triggered another two-week buy setup due to the cluster of 3:1 positive breadth sessions (we consider it a cluster when two 3:1 sessions appear within a five-day time span.) This is identical to the signal triggered on March 8th, when we saw a similar cluster of positive breadth sessions. As I noted at the time, "It's generally a sign of strength when two such lopsided breadth sessions appear within close proximity, and the market has a notable tendency to close at a higher level two weeks later. Since 1984, we've seen this pattern triggered a total of 25 times, 20 of which led to a higher S&P ten trading days later."
Mark Hulbert at CBS MarketWatch points out that today's session triggered a rare bullish signal given the strong 90%+ upside volume on the NYSE. That's the second 90%+ up volume session this month, which triggers a three-month buy setup according to a study originally penned by Martin Zweig. I thought readers might be interested to know when (and how many) previous examples occurred, so we looked back through the last forty years of data to find all examples of two 90% up volume sessions within a three-month time span (parameters suggested by Zweig.) While we're in agreement with the bullish implications of the study, I'd note there have been very few examples since 1965. We found a total of six...
Two 90% Up Volume Days in Three Months
08/20/82... S&P500 +21.2% three months later
10/29/87... S&P500 +2.0% three months later
07/29/02... S&P500 -1.0% three months later
03/17/03... S&P500 +15.6% three months later
08/16/04... S&P500 +7.9% three months later
06/15/06... S&P500 +3.5% three months later
03/21/07... S&P500 ??? three months later
Today's 91% upside volume also brings to mind research posted at the last 90% up volume session in early March. At the time, we noted that such a lopsided volume session has often represented a short-term buying climax, meaning it's been rare to see the market pile on significant gains immediately following such lopsided buying pressure. Instead, the market generally enters into a choppy range or trades lower, particularly over the following session. In the last ten years, we've seen a total of twelve 90% up volume days, all of which are noted in the table below along with the S&P's performance the following session...
90% Up Volume Days on the NYSE
03/21/07... S&P500 ??? next session
03/06/07... S&P500 -0.2% next session

07/05/02... S&P500 -1.2% next session
09/08/98... S&P500 -1.7% next session
While on the subject of advancing volume, I'd also note that today's 91% upside volume comes just two days after Monday's 84% up volume session. When two lopsided volume sessions occur within a three-day time span, it's generally a sign of heavy institutional buying pressure. And this type of buying power typically leads to further upside over the following week. Since 1980, there have been nineteen instances in which we've seen two 80%+ up volume days within a three-day time span. In fifteen cases the S&P was higher one week later, but more significantly there was only one instance in which the S&P was down more than 1% one week later. This implies limited downside potential heading into Wednesday of next week, with support likely to be found in the SPX 1420 area...
