Investors in lululemon athletica (NASDAQ:LULU) have endured quite a roller-coaster ride so far in 2013.

Even though the stock is currently trading almost exactly where it started in January, it's easy to forget that Lululemon shares have underperformed the S&P 500 by nearly 20% year to date.

Of course, that weakness can not only be traced back to March's see-through pants debacle, but also both to the June resignation announcement of the yoga apparel company's CEO and the most recent news that Lululemon's net income will likely remain under pressure through the rest of this year.

But Foolish investor Steve Symington thinks all these troubles have created a perfect buying opportunity for long-term investors, which is why he purchased shares of Lululemon for the first time in his personal portfolio last week.
