Markets had a choppy day that ended with all the major indexes posting slight losses. Investors may still be taking profits after Fitch downgraded the United States credit rating.

However, the markets may also be reacting to oil prices which surged to over $81 a barrel as Saudi Arabia announced it would extend its production cut at least through September. That could be adding to concerns about rising inflation. Investors will get the next read on consumer prices and producer prices next week.

But as this week comes to an end, the markets are eagerly awaiting earnings from Apple which will come in after the market closes. That report, along with the jobs report tomorrow will set the tone for the market heading into another week of earnings.
