ASTON .. My Take, page-5

Your comment lacks thought is quite the kettle calling the pot black, wouldn't you think?!
You're asking for another persons calculations for the valuation of a stock you're considering putting your own money into hmmm.
How about you work out your own valuation then compare it to his, do your own due diligence.
Come to the table with something rather than expecting others to show you their hard work.

I definitely don't buy stocks without considering their future valuation, but I also definitely don't consider other peoples valuations.
I'm proposing you calculate and don't worry about how the previous poster came to his valuation, especially when you have no sentiment toward the stock, but that's just my opinion.
