RE:Obe.r Somebody with 2000 shares to sell kept adjusting their sales price in conjunction with the regular shares, always a penny or two more. I almost wanted to buy the shares at one point just to see if I could actually get them. Hardly any of the OBE. R shares have sold.
if you want an opportunity to play the differential on receipts, I would suggest the IPO.r shares which ten to trade at a discount if 10-20 cents to the regular shares. There is at least enough volume there to make a trade or 2.
