I looked up the reference  in this research paper you quote. It is from a paper published on Nov. 10, 2010. Using research from more than three years ago to evaluate where companies are in comparison to one another today is not a technique I would suggest to anyone. The first paper didn't even get the footnote date right so I am not so sure about anything they state.
Here is the footnote and citation so you can practice your research:

Early November, Dec. 3-4, day before yesterday are all times when its flat topped. When a stock is trading in low volume this is fairly typical (especially end of year or holiday periods). Wait patiently, when investors start looking in earnest for a good 3D play, sigma will be a favorite choice in 2014.
I see a lot of back and forth among posters arguing about whether news is good or bad for the stock price. IMO what is most relevant is whether you believe now is the time to buy or whether to wait for a lower price.
AMAVF is below its 50-day moving average price, a rare occurrence for this stock. Share dilution and insider selling has been announced. EuroMold product announcements didn't seem to move the stock any higher. There is a concern that their largest institutional investor might dump shares. And we all have an opinion about what Gary said. In other words, while there can always be more bad news there is a lot out right now! For me, this is a good time to accumulate on the dip. We have seen time-and-time again this stock gap up substantially on good news.
Please do reply to this message with fact-less hysterics if you don't agree. Just state what other negative news you think might hit and why. Thank you to everyone for staying constructive!
SGLB tends to take a-day-or-two for news to push the PPS up so don't be discouraged if the reaction isn't immediate. This is a great time to buy the dip ... not to be confused with buying into the smallcaphead dip's fudding wrong advice.
Sentiment: Strong Buy
Invested in 69000 today. I just hope you have as much in shorts!
Please everyone, report this abuse with a flag on this predator child!
Thank you for the timely post!
Arcam to make strategic acquisition of metal powder manufacturer to secure supply of strategic raw materials
Press Release: December 13, 2013
This just posted on company website:
"Arcam has signed an agreement to acquire the AP&C division from Raymor Industries for a total of 35 million Canadian dollars (“CAD”) in a combination of upfront cash payment and installments. AP&C is a global manufacturer of high quality metal powders and has been a supplier of titanium powders to Arcam since 2006. Titanium powder is an important part of Arcam’s offering to its customers. With this acquisition, Arcam has secured access to high quality titanium powder for its customers’ quickly growing business. "
Sentiment: Strong Buy
Good approach. Right now there are so few players that are publicly traded that it is hard to choose just the few. Each has a good story and one break can change the fortunes of a single company. May all of your decisions be profitable.
To get SGLB's benefit you have to think like an engineer ... perfect is not the goal, greater control is. GE already factors in the fact that PrintRite3D will not be perfect when they predict a 25% time savings. Believe me, that guy put his job on the line when he made that statement.
Sentiment: Strong Buy
You are so disingenuous (look it up). Day before yesterday, when it solidified at $0.22 you said it was going to 0.18 and insisted anyone who bought in was a fool. Now, when it traded all day between 0.224 and 0.229 you claim it is down like that vindicates your slash and burn comments. Dude ... in never went anywhere near .18. Why don't you own up?
Its your call, but consider that SGLB makes big swings. Your loss today would easily be gained back by a rise like yesterday. You have to ask yourself where is SGLBs going? Market vacillations are part of the game with small cap stocks. The key is to have position in them when they run up which many believe SGLB will do soon. Its history indicates this.
Its really simple, read their press releases, what others have said about them, and them make your choice. But don't spout off that they have nothing when they are active with Morris Technologies at GE, with Honeywell, are given significant roles by American Made (you probably don't know what this means), and they are taking leading spots in workshops at major international conventions. Bye!
