WITH all eyes on back-to-back inflation data coming this week, Wall  Street stocks tumbled again on Tuesday as earnings warnings tanked tech  shares.

Investors may have been taking advantage of a recent upswing in share prices to cash out before the government reports on July consumer prices on Wednesday, followed by producer prices on Thursday.

While the data are expected to show monthly inflation slowing from June, the annual pace is likely to remain near 40-year highs.

There is a real concern about what numbers we can get on the inflation  tomorrow, Thursday and even Friday with the consumer sentiment numbers

There are a lot of things to look at between now and the end of the week  and a lot of profit has been made over the past couple of weeks so I  think there is a bit of profit taking going on

The Dow Jones Industrial lost 0.2 per cent to end the day at 32,774.41,  while the broad-based S&P 500 fell 0.4 per cent to 4,122.47.
