There are several possible reasons that spring to mind:

1. In mental institutions, the inmates have to leave the library and go back to the ward for dinner quite early.

2. Very old people need a nap late in the afternoon and when they wake, they have forgotten whether they own any shares and it isn't until the following day after a longer sleep that the memory returns to them.

3. Even the holders agree it is a highly speculative investment where profits might be regularly taken by smarter traders and so the posting takes the form of transparent barracking for the daily share price, best done during trading hours which, of course close at 4 o'clock.

Jokes aside, as there are only weeks to go until "volume sales" of prescription Ropren commence in Russia, according to the company, you could certainly expect a lot more excited posting at all hours, if that comes to pass - until then, i think holders are just biding their time.
