Sluggish Start

Stocks fell in response to higher oil prices at Tuesday’s opening bell as investors returned from the long Labor Day weekend. Investors kept one eye on diplomatic efforts in the Middle East and another on fresh inflation reports due out later in the week.3

Stocks were under pressure again on Wednesday as oil prices continued climbing. After the Treasury Department announced it was tripling its long-dated debt buyback program (to as much as $6 billion), the yield on the 10-year Treasury note rose to a 3-year high. Investors continued to fret over inflation as the week progressed, putting further pressure on stocks.4,5

On Friday, stocks rebounded after news that annualized inflation held steady in August, puzzling some who expected stocks to decline. Oil prices fell, and markets rebounded to finish a tough week on an upbeat note.6
