Reports on single day / weekly / monthly drops in share prices etc have absolutely no meaning. For example a 6% hit based on chip supply contracts is going to be easily offset with gains when the S3 is released to European consumers at the end of May and the US market shortly after with it's 9 million pre-orders.
To judge a companies success, look longer term and see how their overall strategy has impacted their business over the last 1, 3, 5 even 10 years. The case here being Samsung has gained nearly 41% in the last 5 years.
My point is take things like this with a pinch of salt, it's not going to have any effect in the grand scheme of things, just sensationalism so that websites can increase their traffic figures.
