I assume the deleted first post covers what I'm going to say, but as it's deleted I'm going to say it.
This just feels like a free gift for the legal industry. Even if Facebook are found to have bent the truth shareholders are going to have a hard time proving that they lost out given that the share price is now 3 times its float price.
If there were irregularities in the IPO then by all means the relevant authority should punish Facebook, but letting a case drag on for 3 years while the entire basis of the suit disintegrates just makes the legal system look stupid (for about the millionth time).
Obviously a few people will have sold at the bottom and will feel aggrieved, but I'm sure they're a small minority of claimants here and frankly they shouldn't be allowed to use the legal system to hedge the risks they accepted in buying into an IPO. Anyone who stayed in, has tripled their money and still wants a settlement is frankly insane.
