As Motorola ( MOT), Texas Instruments ( TXN), Nokia ( NOK) and LG report within 24 hours of each other, I would argue that investor focus is going to be almost exclusively on their phone sales volumes. There are periods during which markets fixate on average sales-price numbers, but this is not one of them. The biggest fears now center on handset-volume growth, and this likely will drive the market reaction to Motorola and Nokia and, by extension, component supplier Texas Instruments. All three are well positioned to deliver volume upside surprises. Some are worried about inventory buildup and third-quarter prospects, but in my view it isn't likely these companies will offer detailed commentary on their third-quarter outlooks. They all have edged away from being too proactive on guidance, and this is likely to continue unless there is rapid deterioration in the marketplace right now, which I don't believe.
