Mr. Buffett's statements, with no disrespect, as those of any investor, should be taken with caution. These are not always shared with the intent to share from a vast knowledge and experience, but sometimes have a bias, either because of current investments, future investments or simply the mutual influence and interests of the closest relationships.
I remember Warren Buffett recently said Apple will be the first company to reach 1 trillion market cap. That comes from the position of an investor in Apple stock, who recently increased his exposure to Apple by another 75 million shares through his fund Bershire Hathaway.
