Apple (AAPL) is warning about its 1st quarter (already saying it's going to have lower revenues). Currently Apple's stock is halted for the news (which is temporary) but the QQQ's are down over 1% in after hours as a result of the news. That could set a negative tone for tomorr'w's trading and overnight trading in Asia/Europe. (Apple's stock will resume trading at around 4:50pm EST, from what I hear).
Those of you who are long-time subscribers have known that I've warned people against owning Apple at this time. I'm thrilled we don't own it.
Fundamentally, it's solid and there will be a day to own it again. But we're nowhere near that day today or likely anytime soon.
