That probably had an effect but on the other hand, someone buying $3b (3.5 now) shows a lot of confidence too, so the opposite effect.
This recent decline has noting to with i-Cahn though.
I didn't say specifically this decline did. Whether he influenced prices to fall 30 days ago or today doesn't matter. The price *could* have been higher before this decline last night without his input. Which would make today's price higher than it is.
You admit you have no metric. However we do have metrics that show every time he's disclosed buying more AAPL, and gone on his rants about more and more buyback, the stock price has gone up.
Yes - after it's disclosed. What about when he hasn't been buying but is still "preaching" and the price shuffles down. Has it really always gone up historically. I'm not certain that's a fact. But perhaps you are correct.
