These articles about the Groupon IPO all seem to have the same feel, reporting some chicanery that doesn't definitively suggest that the stock is a turd, but do suggest that the financeers behind this business are treating the entire thing as an exercise in cashing out quickly.<p>I strongly suspect that investment bankers are playing Pump'n'Dump Bingo with Groupon, which is a little like Buzzword Bingo: Each player throws $10,000 in the pot and gets a bingo card. The squares have random stock promotion events on them, like "restates earnings," "cancels road show" or "Cxx resigns." The first person who gets five in a row collects the pot.<p>Right now, the players are checking their cards for "Low float."
