3D Systems has been a "stock of the month" twice already. However, it would be quite arrogant, and very likely incorrect, if I were to act under the assumption that DDD will the only winner in the red-hot 3D printing industry. Therefore, two high-growth competitors have been added to the portfolio...
Stratasys (SSYS)
Positives:
116% revenue growth.
$141M cash, $0 debt.
42% of shares owned by insiders.
Negatives:
No earnings as of yet; forward P/E of 34.
Negative cash flows.
Negative profit margin (-4%) and ROE (-1%).
ExOne (XONE)
Positives:
192% revenue growth.
$71M cash, $5M debt.
37% of shares owned by insiders.
Negatives:
No earnings as of yet; forward P/E of 117(!!).
Atrocious profit (-31%) and operating (-25%) margins.
Heavily shorted (32%).
Here's my current portfolio (growth, dividend, and speculative). As always, I believe in all of these stocks - until I sell them. (Note that AGNC, BBEP, NLY, and PSEC have now been classified as "speculative"...if you would be thinking I am now one step away from exiting these stocks, you might be right.)
