Because it is held in firmer hands? There is virtually no volume in SKRUF. Look at the spread - more than 20% of the value. It went down like crazy (it got to 50 cts, I believe). What I believe is happening is that volume creates volume, and a lot of tech people out there get to look at SKRRF because it shows up on their screens with daily movement. With SKRUF, there is very little to analyze, no interest.
I still believe the expedted upside on both is pretty similar (4 to 5 fold on each). SKRRF has more risk, as it is a junior security. It also has unlimited upside. Most people here are probably thinking that good news will move the stock up quickly because of volume, wheras the pref will move slowly.
Hope you find the above helpful.
