The Friday after Thanksgiving will see a 1:00 pm EST close for the equity markets. The day is usually the lowest single day volume of the year, so it carries very little signficance.
Historically, since 1986, there is a 10 in 15 chance of a positive close on the Friday after Thanksgiving (67% chance of a higher close), but the gains on the day are usually under half of a percentage point which would equate to a little less than 6 S&P 500 points. The Nasdaq is about twice as volatile as the S&P 500 so the price change might be 18 or 20 points.
The S&P 500 has "brick wall" resistance (1153-1200). Immediate support is 1141-1130 then 1134-1122, which makes the 1134-1130 area a focus of support. Substantial intermediate term support starts in the 1110-1096 area.
Immediate resistance for the Nasdaq is 1879-1905. Immediate support is 1848-1829. The index has substantial intermediate term support at 1800-1646. Cherney is market analyst for Standard & Poor's
