Today on Taking Stock | Rising yields and oil send stocks lower to begin September trading. Gresham Partners on volatility and stock valuations, @henrymcphie_ discusses @streamex's mission + @A10Networks rings the Closing Bell! @jd_durkin has more.

The 30-year yield is getting close to where it was in 2007, right before the financial crisis. Ted Neild, CEO & CIO of Gresham Partners, tells @JD_Durkin the low-rate era since then may have been the anomaly, as "we're coming out of this period of interest rate repression."

JUST IN: A Georgia man is walking free after defending his family and property at 4 a.m. when three masked thugs rolled up to rob people in his front yard. The suspects — 16-year-old Isaiah Reid, 15-year-old Jaime Hernandez, and 16-year-old Brandon Gresham, all from Conyers — were masked and armed. One teen opened fire first. The homeowner returned fire, dropping all three. Would-be victims unharmed. Deputies recovered two guns at the scene. Rockdale County Sheriff Eric Levett called it a clear “stand your ground” case. No charges against the homeowner.
