I think that current market conditions have a confounding effect on the performance of exoskeleton stocks. I still believe in the future of exoskeletons and they are going to become more prevalent in our daily lives.
However, ReWalk significantly screwed up their operations. I don't know exactly why but for some reason, it looks like they were hoping to get insurance coverage in 2016-2017 timeframe. Otherwise, I can't explain why they chose to get a loan from Kreos rather than raising money by issuing new shares. When they realized that they wouldn't get insurance coverage, they got into the China JV adventure and Jasinski really screwed up how to move with that plan. He made many empty promises to the investors, and couldn't manage to get a deal at the end. Hence, we ended up with $.2 PPS today. At this level, I think the company is significantly undervalued if they can continue their operations. Since I didn't/couldn't sell while the PPS was going down like crazy, I am a bagholder with 12,000 shares (including a very recent purchase at the current price level). I am not planning to put any more money into RWLK and I am fine if I lose everything here (and there is a significant chance that will happen)
I don't what is happening with Ekso. I still keep more than 4,000 Ekso shares but the current price movement is worrying me. Even though I value the diversification of EKSO product mix, the industrial exoskeleton market is very competitive and I am not sure whether EKSO will be able to lead that market.
Overall, I have decided to sit & wait. I am not going to allocate new funds for the exoskeleton stocks but I am not going to sell what I have either (unless there is a significant positive move). I may end up losing everything (opportunity for writing tax losses :) ) but that is a risk I will take (selling at this point doesn't make a lot of sense)
