Some comparative figures for the video:
GE:
Mkt Cap: 417B
Rev: 163B
Inc: 20B
BV: 112B
XOM:
Mkt Cap: 527B
Rev: 377B
Inc: 39B
BV: 113B
PTR:
Mkt Cap: 448B
Rev: 91B
Inc: 19B
BV: 77B
All numbers are from 2006 for comparison purposes and to give each company the benefit of the full year. Some companies my have had special charges that would influence ratios to earnings and book value, I did not check. None of these figures represent future cash flows, but I would imagine for the most part PTR and XOM would suffer similar fates.
