Posted it in another forum also but I think this might be helpful for ES traders more directly.
Just went through couple of surprise rate cuts, with market's response some days before and after the event. Two different years, different cases, different conclusions as to how market reacted after the surprise rate cut.
In 2008, market continued to go up for a week post rate cut and then came back in 2nd week.
In 2001, market gave back gains post rate cut within 5 calendar days, and took 16 calendar days to come back to the high level set post rate cut.
2008 Jan 23 (75bps surprise rate cut when Fed Meeting was scheduled for Jan 30th):
Date S&P Opening Levels
2-Jan-08 1468
9-Jan-08 1390
17-Jan-08 1375
23-Jan-08 1310 (LOD 1270, HOD 1339)
25-Jan-08 1357 (HOD 1368) -- so a Low to High rally of 98 points in 2 days
30-Jan-08 HOD 1385
1-Feb-11 HOD 1396 --- rally continued for a week after Fed's action
7-Feb-08 1324 (LOD 1317) -- Gains given back almost after 2 weeks
2001 Jan 3 (50 bps FF rate cut and 25bps discount rate cut)

21-Dec-00 1264
29-Dec-00 1333
3-Jan-11 1280 (HOD 1347 after rate cut during mkt hours)
4-Jan-11 (HOD 1350, LOD 1329) -- so not much different from previous day HOD
