Apple supply a good product, good sales, and is not dependant. Samsung share price is a relation to Samsung. The phone business in Samsung is a part of the whole. I am of the opinion that a lot of negatives on Apple's stock, is a result of a small percentage of people "attacking" Apple's products. And to attack is easy, as the number of products are very small. Investors, that are by the way a lot less than users of the product, are making nervous moves. It would be the same if one negative remark on Google for example, will be made, and everybody in the market attack android. Samsung is dependant on Google for Android on the phone side, and to attack either of the two, will attack a whole system where the product attacked is a very small portion of the whole. The negative for Apple is that the number of products are very little. But they are doing something right if you look at their sales figures and performance. If I was an investor in Apple stock, the movement won't make me nervous. I personally think the price was inflated at a stage, and things are moving back to normal.
