HUM only up slightly due to AET being knocked down and the overall market down because of Greece. If you are holding the stock or even July/August calls, it will creep higher. Don't let the pre-market scare you into selling on the open. You'll regret it. With Aetna down 7-8 points the deal is still about $224. Take off 5% or so for timing/risk and it should creep to about $210-212 soon.
Even if it takes that long, that's 8-10% below deal price. Arb's would take an 8% return everyday. It should be closer to 5% per year if you think it will take that long. I don't. I say $220-222 and only if Aetna's share price takes a hit.
Sadly I think vacinemaxine is right. This was completely expected. They had a 12-1 approval vote at the panel meeting and the premium has been built in. This is good news but expected news. Any pop I expect to be small, maybe to $132 then will pull back but probably not a "huge flush" like you say.
I understand their is some value in the unknown like the future of electric cars or these new batteries but I have no clue how this company can be worth $30B. Elon Musk is a smart guy for sure but the valuation to me is about right only if everything goes very well and it's like 10 years from now. They have negative profitability and probably due to expansion but even if the company surpasses their own expectations the numbers don't add up. I guess hold the stock if you have it as it seems like investors are in love with it but I have to believe there are more attractive companies to invest in if only based on the numbers.
