It very much needs to test 435. It also needs to fill gap at 425. After that it needs to test low of 419. That would be double bottom low on a monthly chart. Once stock does that, I would be all in long. I would load the boat at 419. Until then I stay short.
The next support line is down 420-425 area, I would think it would have to come down and touch the next major support lvl before we get a chance to come back up. We didn't get a close above the 463 lvl where it opened up the day of the major drop, which doesn't look great.
This last week looks more like a rising bear flag, combined with the horrid vol. Its just an opinion but, to me it says we have to touch that 420ish area before we move back up.
