Pullback

A pullback is a pause or moderate drop in a stock or commodities pricing chart from recent peaks.

In the example above, the SPDR S&P 500 ETF (SPY) experiences four pullbacks within the context of a prolonged trend higher. These pullbacks typically involved a move to near the 50-day moving average where there was technical support before a rebound higher. Traders should be sure to use several different technical indicators when assessing pullbacks to ensure that they don’t turn into longer-term reversals.
