Apple (AAPL: sentiment, chart, options) returned to the headlines last week following a pretty long hiatus. As my colleague Mark Fightmaster reported, the company announced an "all-you-can-eat" music plan with its iPhones and iPods. The news has helped usher the shares steadily higher during the past several sessions. However, there is a crucial test of this rebound looming on the technical charts.

A while back, Apple broke below a long-term trendline that connected the stock's pattern of higher lows, culminating in a bearish "bump and run" formation. Following a sharp downside move after the breach, AAPL is now poised to test this trendline for overhead resistance. Complicating the matter is that former support at the 145 level is also in the region, and could now act as technical resistance for the shares. So far, AAPL has struggled with resistance in the region during the short term. A rejection here would be bad for bullish investors, as it could send the shares back down to the 130 region in short order.
