The stock price appreciates on 2 events, the release of the latest version of their existing products, or an earnings announcement. At some point in time, it will get hammered by the real world - US recession, Iran vs another country, near total loss of Chinese market to counterfeiters, etc., i.e. external factors beyond their control. For the time being, the more they churn out improved versions, the more cash gets hoarded. Don't get me wrong, I am just being realistic, and one happy camper, in at $194.30 .
saving nickels saving dimes
working till the sun don't shine
looking forward to happier times
