MarketWatch puts it succinctly: 'the bigger Groupon gets, the more it loses'. Although it's not the firm's fault, the timing of this filing amendment couldn't be worse - investors are likely to psychologically associate it with the market instability. Not that I'm qualified to dispense investment advice or anything, but my bet is that this offering will either be under-subscribed or the firm will end up under-capitalized and the founders will get ejected within a year of being listed.
