Why 3-D Printing Software Maker Dassault Systemes SA's Stock Apparently Crashed 49% in One Day

This article was updated on Aug. 13, 2015.

Some shareholders in 3D printing software maker Dassault Systemes (NASDAQOTH: DASTY  )  got a huge jolt on July 23, 2014, when it appeared on Google Finance, Yahoo! Finance, and other top financial sites that their stock had plummeted 49% in a single day. I wrote soon after the close of the market on that day that they could rest easy, as Dassault had not suffered a massive sell-off, despite what their stunned eyes were seeing on their computer screens. The France-based company's stock had split 2-for-1 on that day, and that fact had not yet been reflected in the price-per-share data on the financial sites.

That news appeared nowhere on the financial sites, so I had to first assume -- we'll get to why I immediately made this assumption -- that it was a 2-for-1 split. After some investigation, I found the following on page 3 of Dassault's first-quarter 2014 earnings report released in March 2014:

The Board of Directors has scheduled the Annual Shareholders' Meeting for May 26, 2014 and is recommending a 4% increase in the annual cash dividend per share equivalent to €0.83 per share for the fiscal year ended December 31, 2013, compared to €0.80 per share for the fiscal year ended December 31, 2012 and a two-for-one stock split effective from July 2014. (emphasis mine)

A telltale sign of a split, or how not to be freaked out: Daily volume
This type of delay in financial sites reflecting stock splits isn't uncommon, especially when we're talking about foreign companies trading over the counter in the United States. A similar scenario played out earlier in 2014 with Sweden-based 3D printing company Arcam. In Arcam's case, the stock split was a less common 4-for-1, with the share price appearing to plummet about 70%. (The stock was up that day, which is why the drop was less than the 75% it would have been to account solely for the split.) According to comments on my Arcam article, some investors didn't know what was happening. So, I knew some Dassault Systemes investors could be just as panicked. 

If you ever see a huge drop in stock price, it will be almost surely be due to a stock split if the daily trading volume is just average. All the major sites list daily trading volume, as well as an average (usually a three-month average) trading volume.

Since the original version of this article was published, there have been no "real" big drops in Dassault's stock. In fact, it's been doing well -- its year-to-date 2015 return is 23% versus a mere 2.7% for the S&P 500. It's also beat the market over the last one-, five-, and 10-year periods, too. Look for more current coverage of Dassault Systemes coming soon.

One bleeding-edge technology is about to put the World Wide Web to bed. And if you act right away, it could make you wildly rich. Experts are calling it the single largest business opportunity in the history of capitalism... The Economist is calling it "transformative"...

    I came to the same conclusion after much web surfing (which revealed that the stock was, in fact, up about 1% today, and had a p/e of 17+.) So I didn't buy it.

    They don't even mention the 2-1 split on their bloody website!

    I understand your frustration. I don't know why companies don't make sure to release a quick PR a day or two before the actual split, so it's posted on ticker feeds, and quite visible on the Investors Relations sections of their websites.

    If a stock "drops" 50% and there is no huge increase in volume, then you can be confident the stock is not crashing!

    I nearly panicked when I saw that! Had I not been a moderately seasoned investor, I might have done something drastic. Fortunately I did my own digging (for about an hour), hoping all along it was a split, and then strangely remembered that I'd read something about that awhile back. I'm glad google and yahoo caught up, but I fear for the newbies/day-traders (which could have sent it even lower, especially if they had stop limits in place)! Even my online broker was showing a harsh loss in my account, and probably would have sold my shares if I'd had a stop order in place (fortunately, I don't typically use those either). Anyways, hopefully these lines of communication get cleared up in the future lest people accidentally sell their positions or make an uninformed decision.

    They most certainly did mention the split on their web site. Read their news page carefully.

    "2014 full year outlook reaffirmed and EPS objective adjusted for two-for-one stock split"

    I'm sure you're not the only one who panicked. I just don't think investors should need to spend an hour, as you did, or even less time digging. In some cases, it's a given that there will be a delay in adjusting the price-per-share data on financial sites. So it would seem simply enough for cos. to post a reminder PR a day or two before that makes it onto ticker feeds.


    That item was posted today July 24 -- a day after the fact.
