Well, IMHO, the LEHMQ, cause of the liquidity & the fact that it can trade 100 mil shares/day or more. The prefs, IMHO, should be played for a payout at the EOD and, if possible, selling enough to ride freebies. A payout of .05 on the dollar on a $25.00 pref share is $1.25/share...isn't that the objective on the pref & hence the lotto play? Heck, even a .01 payout on the dollar is .25/share on a $25.00 pref.
Different strokes for different folks but it's all good.
