of trading on a day like today looks like the crude drawing below. The market gaps higher, experiences a little shakeout, continues to rally and then churns midday. The midday churn sucks in a lot of short sellers, particularly on a 1-1:30 pullback below the daily VWAP. If the market rallies back above VWAP there is often a strong continuation into the close as short sellers scramble to repurchase shares they sold lower.
This is not meant to be a blueprint of how to trade today, it is just one scenario which I have noticed on these type of days. LISTEN TO THE MARKET and manage risk, the primary trends are still lower.
