At least Andy gives us regular updates on progress being made on the various projects. Some of the companies I'm invested in only seem to want to report earnings four times a year, and maybe an occasional private placement or two.
Progress updates are important for supporting investor interest and the stock price...usually.
I have no issues that way either. Have made decent gains over a long period of holding and will continue to hold but I feel that Plug should have been surging ahead past the 70s and beyond.
