Amlh has many more problems than the yield sign... I'm a fan and one time shareholder, but I won't be back in until I see something substantive from them
The different AMLH is alternative reporting company it is a pinksheet. They do not register with the SEC. They don't require the SEC audit accounting, therefore, the stock remains in yield until they update with all the files then it up grade to pink current info. right now is pink limited information
OTTV is a full reporting company they are full register with the SEC their files require full edit by SEC qualify accounting.
