A statue of a defiant little girl was placed in front of Wall Street's Charging Bull to challenge the 'traditionally male environment' of the industry, ahead of International Women's Day.

A brave bronzed girl was installed with her hands on her hips, head held high as she faced off against the hulking statue of a bull on Tuesday morning.

The campaign calls on more than 3,500 companies to take steps to increase the number of women on their corporate boards.

The stunt, timed to International Women’s Day today, is meant to symbolize the power of women in leadership. 

It was placed by $2.5trillion asset manager State Street Global as part of a campaign the company is launching to increase gender diversity in Wall Street's 'traditionally male environment'.

“We believe good corporate governance is a function of strong, effective and independent board leadership,” Ron O’Hanley, president and chief executive officer of SSGA, said in a statement. “A key contributor to effective independent board leadership is diversity of thought, which requires directors with different skills, backgrounds and expertise. Today, we are calling on companies to take concrete steps to increase gender diversity on their boards and have issued clear guidance to help them begin to take action.”

The Fearless Girl is a symbol of the firm's hope for women to become recognized leaders in the field, symbolic of International Women's Day, where women are encouraged to be bold, walk out of work and not spend money on Wednesday.
