Biggest 1-Day S&P Constituent Moves

Google is up over 85 points, or 18 percent, Friday. Here are the biggest one-day moves of the S&P 500 constituents (adjusted for splits and dividends):

Biggest 1-Day Percent Move:
MEMC Electronic Materials up 118 percent on 10/1/2001

Biggest 1-Day Point Move:
JDS Uniphase up 171 on 7/20/2000

The Google move would rank No. 3 in point moves.

On an unadjusted basis, Qualcomm had the biggest point move of 156 in December 1999. Google's move today would still put it in third place for all time.
