We needed a small pullback. Now we can continues upwards. Whenever a stock has several days of decent gains, everyone starts anticipating a pullback. The more days of gains, the more people believe this will happen, which causes traders to often take some off the table. Thus it becomes a self fulfilling prophecy.
Now that we lost a couple cents today, we can have a few more days of gains until the cycle repeats itself. Hopefully have a nice day tomorrow.
