I have stops in place just in case, but it held the trendline perfectly if the chart is set to logarithmic on the daily. personally i would find it confusing how anybody loses money playing this one long.
SSYS is definitely the way to go. DDD is still way over valued at something like 50x forward earnings. If it is one thing I have learned over the past 25 years of investing it is to NEVER invest in a stock that has more than 20% of the float sold short. DDD is something like 30% short interest.
Barrons had an article bashing 3D Systems this weekend. SSYS is the industrial leader with MarketBot as the kicker. Cutting edge stocks are always expensive. You will never buy a stock that people will think is the next big thing cheap. I am long term long.
