The Dow Jones Industrial Average achieved a milestone, topping 20,000 for the first time in the stock market index’s 120-year history.

In the past two months, the Dow has gained about 10% in value.

But fastener stocks have done better than that. Since January 1, public companies with fastener holdings have collectively achieved share price gains of 11.1%.

Fastener companies achieving growth of 10% or more during that past month include Arconic (up 23.3%); Carpenter Technology (up 11.8%); Grainger (up 10.3%); and MSC Industrial (up 12.1%).

However, the gains were not evenly distributed. Three of the 20 public fastener stock companies tracked by GlobalFastenerNews.com saw share value decline during the period. Those companies were Dorman Products (down 6.9%); Tree Island Steel (down 5.5%); and TriMas (down 8.5%).
