Don't go assuming what Chair Yellen will say, or that she will somehow give deference to markets. If anything we've seen her take a stance against the market heights in the past, and lambast QE for its profiting the wealthy and increasing the income inequality.

See John McCain, heck even George Wallace changed his tune toward the end.
