Quote from Pekelo:
What can be a valid observation for a particular stock doesn't need to be valid for an index.
The SPX rallied 110 points in 2 weeks from March 18th. According to you that is largely due to overnight upgaps. Unfortunatelly for the theory there were only 2 upgaps that hadn't been filled right away, one was only about 15 or so points on Apr 1st and that day's 43 or so gain came mostly from the rally DURING the day and not from the upgap of 15 points.The other was when the rally started on March 18th...Again, 60+% of the day's gain came during the day and not from the gap...
So your theory is nicely refuted by the intraday advances of March 18th (35 points) , 20th, (30 points) 24th (20 points) and Apr 1st (28points).
Of course I could show the same intraday movements for the selloff of the beginning of the year.
Your statement was simply ridiculous....
