In a note to clients — as reported by “CNNMoney” — Topeka analyst Brian White, who tracks the performance of a collection of Taiwanese electronics suppliers as a “barometer” of Apple’s future performance, says, with only one company in his “Apple Monitor” not yet reporting, sales among these suppliers were down 13% month -over-month in June, compared with an average 1% increase over the past seven Junes.

For the June quarter, sales among these suppliers were down 8% sequentially, well below the 8% uptick in the same quarter over the past five years but still above the guidance Apple offered in April, which according to White called for a 13% decline. For more info go to .
