Wall Street’s three-and-half-ton bronze Charging Bull has stood frozen in mid-charge, to meet oncoming traffic just above the bottom of Broadway for nearly 30 years. It’s a symbol, the artist Arturo Di Modica would say, of achievement and optimism—of the American capitalist’s unbridled bravado. Until last month, that is, when the big bull lost his swagger to a little girl. And now Di Modica’s ready to sue for that swagger’s rightful restitution.

On March 8, International Women’s Day—and, this year, the “Day Without a Woman”—the Boston-based mutual fund management firm State Street Global Advisors unveiled its politically fashionable addendum to Di Modica’s bull: staring down the beast, a 50-inch-tall bronze schoolgirl with her hands on her hips. (You’ve probably seen her on social media.) Fearless Girl was to be a temporary installation, intended to promote State Street’s year-old index fund for gender diverse companies, and to bring a plucky ponytail to the Bowling Green park in the name of girl power—but just for that one month. The girl’s stalwart stance against Di Modica’s, apparently, male chauvinist bull so delighted celebrities, Clintons, and even the occasional ordinary person that her stay on the bull’s traffic island was stretched to a full year.
