What: Shares of The Container Store Group (NYSE:TCS) fell as much as 9.8% Monday despite no company-specific news.

So what: At the same time, the volatility isn't entirely surprising. It has only been a little over two weeks since The Container Store's painful fiscal third-quarter 2015 results, which caused shares to drop more than 40% in a single day after the company not only fell short of consensus revenue estimates and reported a surprise net loss, but also blamed disappointing guidance on a "challenging" start to its crucial fiscal fourth quarter that runs from December to February. The stock has endured multiple big moves since then, most recently including a questionable 11% gain on no news this past Thursday.

Now what: Though CEO Kip Tindell insisted that "key initiatives are gaining momentum [...] as we position our company for sustained, long-term growth," the only thing that seems certain at this point is that the stock will remain volatile until the company shows concrete progress toward achieving that sustained growth in the coming quarters. Until that happens, I'm personally content continuing to watch The Container Store's stock from the sidelines.
