The math is off as it is only accounting for 3600 btc mined per day which hasn't been true for months.
Reworking the math shows that basically for every 1% of the network Labcoin holds, their value per share goes up by .002.
1% = .002
2% = .004
3% = .006
4% = .008
etc..
You can see that even if they don't hit their 500TH goal and only are able to obtain 250% or around 4% of total network hash rate, we are still in for a nice gain.
As you well know Vela, stocks are not always valued by their current performance... You have to factor in risk and potential. It is my opinion that the potential is closer to .015 in 2013 and the risk unfortunately is currently very high. Once the risk lowers, we will start to see the stock rise.
first they need to achieve 1%, which is still a stretch. If they get that done by Mid Oct, THEY MIGHT be able to pull off 50 TH/s by Nov 1.
So, until Nov 1, they really aren't worth .002 btc, by your calculations.
And I agree, the risk is very high, they are unlikely to be able to achieve 1% by Nov 1.
