SBV11 chart mystery may be solved ....
I get the same precise values you just posted here:
Feb 2/2011 the high was 27.55 and the close was 27.53. And that was the high of the contract. "
If I switch to a continuation chart for a longer term, I get the values (bars) up in the 33 area.
Looking back at your May SB chart you have bars up in that area also. So, looks like have to be quite careful on this.
I was looking for an "upper bound", "all time high" for SB just to gauge how far it might go, and so far it looks like the 33 area. This look was prompted by seeing quite a few Call options above 30 at present for SBV11 (Oct).
Have to be careful !!
