“you should be identifying those companies which make the components of the iPhone and investing in them as their sales are sure to grow “
There is not really any new technology involved in the parts of the iphone, and most of the suppliers are allready making parts for the half billion or so other cellphones ( or laptops, pda’s etc. ) being sold.
For example, the bluetooth chip supplier says they supply 50% of the world market for bluetooth chips in consumer products. Any increase in orders by Apple may well be countered by a decrease in orders from other manufacturers.
The assembler may very well have a large increase, but the “Made in China” sticker on the iphone may pose a problem for investment.
