These are called "winglets". They are there to prevent vortexes from forming at the wing tips as they would without them. These dual vortexes, (one at each wingtip) create drag, thereby reducing performance, and increasing fuel burn rate. Many smaller jets and turboprops are being fitted with them, not just large commercial planes. The primary benefit is reduced fuel consumption.

The winglets reduce drag and increase efficiency by carrying the wing vortices away from the surface of the wing itself, thus allowing the wing to be efficient its full span. Without them, the last few inches of the wing would be turbulent and not creating lift.

winglets reduce drag.

they are called winglets there main pupose is to give the aircraft more stability at higher altitudes where the air is much thinner.. they can also reduce your stall speed too

they are called winglets they improve aerodynamics
