Surrounded by cheering Apple Store employees, one of the first iPhone buyers leaves the store on Fifth Avenue in New York.
The company is expected to launch a smaller phone on Monday that is believed to be called the iPhone SE. It will also drop a 9.7-inch iPad, slightly larger than the original iPad 2.
In the six months after a new iPhone launches (the first was released in June 2007), Apple shares have rallied every time but once.
According to Yahoo Finance, Apple's biggest gain in the six months after a launch was by 64%. That came after the first-generation iPhone release, which was a game changer for the industry.
The S&P 500 rose 62% in the same six months.
The only loss over a six-month period after an iPhone release came after the iPhone 5's September 2012 debut. Apple shares fell 35% during that window.
In the years after new iPhone launches, Apple shares have rallied every time except twice. They gained 96% from the July '09 launch of the iPhone 3GS.
They went positive for 2016 on Friday, one day after the Dow Jones Industrial Average also returned to the green, following the worst-ever start to a year for the US stock market.
Apple shares usually go up.
