Let's take a look at the charts to see what happened last week
The SPYS had a nice upward bias through mid-Wednesday. They spiked after the Fed announcement then consolidated for the rest of the week.
The QQQQs rose a a bit until mid-Tuesday when they consolidated their gains. Then they spiked after the Fed announcement and consolidated for the rest of the week.
The IWNs rallied from Tuesday morning until the Fed announcement, then rallied hard on the rate announcement. Like the other two averages, they consolidated gains for the rest of the week.
All three charts are solid charts going forward -- all three have strong upward momentum.
Looking at all three charts from the daily perspective, all three closed the week out below important resistance levels. If the markets want to continue higher they will have to cross and cloase above these levels.
