So Buffett doubled up in JNJ, Soros in MSFT, and Lampert in Citi. Couple of observations:
1. None of these stocks are going to be takeover candidates, just investments.
2. When you have $1billion to invest, you really can't park it in any old tech stock.
3. As investors, these guys are good. As traders, you could do a lot better. One of Buffets top holdings, Coke, has done nothing until this year. You would have done better in cash and waited for the breakout.
4. Markets will be liquid until they are not. Just last week C traded 15mm in blocks at the 53 level. Where were those buyers in March at the 49 level? Running screaming "sub-prime" disaster. Hey in 2000 we had the biggest M&A activity of all time, did not keep the investors happy forever.
All I am saying is be careful. Diversify and do not chase. There are times to load up, but I don't see this as one of them.
