Materialise stock has been on a roller-coaster ride: It just plunged 13.4% Thursday.

What happened

Materialise (MTLS -0.78%) stock gained 42.3% in December, according to data from S&P Global Market Intelligence. That brought its 2018 gain to a whopping 57.6%,

However, shares of the Belgian-based provider of 3D printing software and services have declined 5.3% so far this month, through Thursday, Jan. 10. They had been continuing their positive momentum this month until Thursday, when -- BAM! -- they plunged more than 25% in early trading before recovering about half their losses and closing the day down 13.4%. 

For context, the S&P 500 declined 9% last month and has returned 3.6% so far this month. Shares of the two big 3D printing players, 3D Systems and Stratasys, dropped 17.9% and 15.8%, respectively, in December, and are up 9.6% and 8.1% so far in January.

So what

As for December's big pop, Materialise didn't release any material news last month, nor was any notable positive news reported about it. So we can't pinpoint the reason for the stock's big upward move.

 It seems a possibility that the stock showed up on some traders' and/or investors'  radars due to Materialise's notable third-quarter earnings beat. (On Oct. 31, it reported earnings per share of $0.04, while Wall Street was looking for just $0.01. Moreover, revenue growth was strong, jumping nearly 45% year over year.) 

Materialise has been performing rather solidly recently and its stock has been rewarded. The following chart shows the stock's three-year performance, through Jan. 10:

As for Thursday's big drop, it would seem that some profit-taking was at play, after the stock's huge run-up in December.

Now what

While there are things to like about Materialise, for now, most investors should probably stay away from its stock until the volatility dust settles. More profit-taking could be coming.
