If you're holding Apple (AAPL) stock, you couldn't have been oblivious to the rough month it's had. Apple ended Monday in slightly positive territory, up less than 1% to $634.72. That's down from the $700 range last month.

In this video, MSN Money's Charley Blaine explains some of the headwinds the company is facing, including supply issues and competition.
Apple is one of the most well-known companies in the world. Making a remarkable comeback in recent years, starting with its iPods, the company has changed the way we use technology. Its computers, iPhones and iPads have been dubbed revolutionary.

Meanwhile, its stock has also had a fantastic climb over the years. It continued to perform well after the passing of Steve Jobs, its co-founder, visionary and CEO of many years. In fact, the company has become the most valuable in the world by market capitalization. And its weight in the Nasdaq 100 is so large that the index often moves along with the stock.

This is why the stumble in the stock has been front page news this last month. Blaine discusses Apple's stock valuation following the recent dip, agreeing with many analysts that the stock may be undervalued.

He adds that he still believes investors would do well by it, although not at any price point. In the video, Blaine also explains which price would be a good entry point.
