What happened

Shares of Synchronoss Technologies (SNCR 1.86%) slumped on Thursday. There was no company-specific news driving the decline. The latest development was on Nov. 20, when Synchronoss received a letter from Nasdaq threatening suspension and delisting unless it requests a hearing, which the company said in a press release that it intended to do.

Synchronoss hasn't reported quarterly results since February of this year. The stock was down about 13% at market close.

Now what

Synchronoss will need to present a plan to regain compliance soon in order to avoid delisting. Investors are waiting on three separate quarterly reports, and the company is still working to restate its results for 2015 and 2016.

Until these issues are resolved, expect the stock to continue to swing up and down.
