Aerospace and Defense Stocks Flirt With Worst Week in Years

Uncertainty is taking a toll on the aerospace and defense sector as tariffs, talks of a trade war and personnel shuffling in the White House pressure stocks.

The S&P 500 Aerospace & Defense Industry Index fell for the third day, widening its retreat to as much as 5.1 percent this week through the gauge’s lowest reading on Wednesday. The index pared some losses, but that would put it on pace for its worst week since August 2015 when concern about China devaluing its currency rippled through global equities and sent the index down by 5.7 percent.
