I don't see the connection to volatility myself, but a lower stock price is good news for a company that supercharges its PER SHARE growth rate by buying back its own stock. Continuing to pay a dividend that is only about 22% of net earnings shouldn't be much of a struggle and earnings should increase in the future once the cost (~$1B?) of reducing the work force (~2,000 terminated?) has been worked off.
I'd worry more about BYD, 1211.HK. It's dropped about 24% over the last week, from 32.95 HKD on 6/18 to 24.90 HKD on 6/25.
Jad, I agree, it has no connection as you say. That has been my point all along.
I am perplexed by your interest in BYD. As I remember, you are not a BRK shareholder, and you are not a BYD shareholder. I'm not concerned at all. As of Fridays close, I have a 48% annualized rate of return on that one. I'm guessing, BRKs return is similar.
