I think them wiping out the order book made people mistakenly believe everyone panic sold down to sub-IPO. Definitely cheap at this point (as long as the hashing is legit)
but the hashing hasn't improved, and they are still severely behind schedule. Read some of the discussion yesterday about what their share price would actually be worth IF they are able to achieve even 1% of the network (hint: .002 per share). Currently, they have .06% of the network.
EDIT: looking at the last few payments, it's clear that the hash rate did not improve, as Ytterbium had suggested. The reality of the situation is that the hash rate on the BTCGuild page is likely Labcoin's current hash rate.
