APPL has been strictly following an upward trend since 2009 and I don't apple will break this trend anytime soon. However, that doesn't mean there is no downside potential. Since 2009, whenever APPL reaches the top of this trend line, a correction is followed afterward. The way apple is setup now makes me believe a correction will follow in the coming months.
Apple got lousy sales on its latest phone, and i believe phones with snapdragon processors will become more desirable as time increases. Apple does have a huge brand name to it, but i believe the Hype will only stay in the united states. I doubt that apple will be able to keep up with the growth of its stock this year. I believe once apple reports its earnings a downtrend will start to ensue.
Although I do believe a correction is possible, I think some of your research data is flawed. Based on the last ER, phone sales are doing just fine. Also, service revenue is increasing at a dramatic rate. Substantial year over year growth in R&D spending indicates new products (not necessarily phone related, like cars) are imminent. Still, I think a gap below $177.50 next week starts a bear cycle on the daily chart. I'll consider any drop a retrace as long as it stays above $166. Below that could be your correction.
