Dow Jones industrial average ends day down more than 500 points, worst day of 2015

NEW YORK —Global stock markets are getting a gut check this week.
The Dow plunged as much as 500 points at one point on Friday, its fourth straight day of losses. Around the world, major indexes also fell for the week and most are negative for the month. The Dow has fallen over 5 percent so far this week, marking the biggest drop in four years.
According to Fox Business, the plunge is nearing “correction” territory, meaning a 10 percent drop off in a short period of time.
