Charles Schwab Chief Investment Strategist Liz Ann Sonders says she thinks volatility will pick up in coming months, but that the looming debt ceiling negotiations won’t lead to the major market shocks that occurred in 2011 when the ceiling was last addressed. Sonders tells Bloomberg that volatility isn’t a bad thing, and that most long-term bull markets tend to have decent volatility. She also says she thinks earnings estimates are a bit high, but that attractive valuations mean stocks can withstand some more downward pressure on earnings estimates.
