What was IWB’s worst drop?#

A drawdown is how far a fund falls from its last high point. IWB’s worst fall was −55.4%, from October 9, 2007 to March 9, 2009. It got back to that high on March 19, 2012.

The chart shows how far below its last high the fund was on each day. Big drops are normal for some funds. They matter because selling during a drop locks in the loss.
