Though the three indices closed lower, their declines were limited. The DJIA, down the third day in a row, lost -.05 percent. For the NASDAQ, off -.13 and the S&P500, at -.20 percent, however, today represents only the first decline after Fridays positive closes.
Considering the extent and the range of this trading, and recognizing that it fits into the interval of minus .25 percent to plus .25 percent, we identify these on the accompanying diagram. Of course the magnitude of the zone is arbitrary; it nevertheless permits a logical approach to ascertaining the markets volatility. Since only 610 sessions of the 2,632 trading days since January 2000 fall into the bracket, the chosen range represents only the smallest 25 percent of all daily changes.

2000 38; 2001 40; 2002 37; 2003 51; 2004 86; 2005 78;
2006 100; 2007 79; 2008 30; 2009 40; 2010 to 6/25 29.
You can find the actual count of the dates in this small change group for the past ten years and the last six months just above the horizontal axis. A quick scan of the numbers, combined with a glance at the S&P500 closing prices, reveals a coincidence of incidents and price trends.
The first three years, when values fell, show a much smaller count than occurred during the 2003/2007 expansion. Similarly the incidence decreases during the following decline, between 2007 and 2009. Finally, so far in 2010, the count of these small change days, at 29 for near the first half of the year, seems in line with the earlier mold that the trend of price increases and the number of small change sessions run on parallel tracks.
Accordingly, a market projection, consistent with these facts, would favor a scenario of prices moving higher.
DJIA -.05 percent
NASDAQ -.13 percent
S&P500 -.20 percent
