Today's stock market: The Dow had its worst week since March as attention shifted to Powell

 With the Fed chair Jerome Powell spoke at the Jackson Hole economic policy symposium the next week, the Dow barely managed to win, but that was of little consolation as stocks suffered their worst weekly loss since March.

The Nasdaq dropped 0.20%, the S&P 500 gained no points, and the Dow Jones Industrial Average increased by 0.1%, or 27 points.

                          As Treasury yields continue high, Alphabet leads the tech sector lower.

Fears that increasing Treasury rates, the adversary of growth industries like tech, could continue to advance caused tech to increase losses, which were previously driven by weakness this week. Powell is expected to underscore the necessity for higher for longer rate environments at the Jackson Hole symposium next week. 

Just one day after closing at its highest level since 2007, the 10-year Treasury yield took a break on Friday.

The 10-year Treasury yield might go more on the up side and break out to almost 5%.
