I am relatively new to this site and want to learn more about investing in companies I don't know that well, so I have two or three questions:

dolcevita writes:

"MSB is extremely cheap"

QUESTION: can i ask how the cheapness is calculated for this sort of company, given it doesn't pay dividends, as you said. do you have a valuation technique for estimating the value of the company?


and then docevita also writes:

"...it is demonstrably a manipulated stock..., and the logarithmic trading which manipulates the SP on low volumes"

QUESTION: i'm not sure how this manipulation physically happens. can someone tell me (in very simple terms)? and is there somewhere that I can see it being demonstrated?


and pa31 wrote:
""I see the shorters and manipulators are at it again today."

QUESTION: how or where do you see this? does the Stock Exchange publish this info? and if so, how freqweuntly, and how can I obtain it? do I need to subscribe to a service?


thanks in advance

shorting is something I don't really understand as ive never done it
