About 1,900 registered investment adivsors are congregating at IMPACT, Charles Schwab’s annual conference, where industry experts and analysts converged to share ideas about the market environment and shifting habits in investing.

For instance, investors are still entrenched in defensive plays, with health care stocks as one of the best performers so far this year, but it won’t last.

“We’re going to start seeing those companies that will be more aggressive in capex. That should be the natural cycle,” Omar Aguilar, chief investment officer for equities at Charles Schwab, said on CNBC at the Schwab IMPACT 2013 conference. “So far investors seem to be rewarding companies that are more conservative. As we go into next year, that’s going to change.”

Looking ahead, Aguilar cautions that political drama on Capitol Hill and stretched valuations could hinder further market gains.
