Is buying a lottery ticket considered an investment? 
Something that is missing from the discussion is the actual market for the lottery ticket -- if a market existed for the tickets themselves, that would make this far more obvious, but since there isn't one; buying a single ticket gives different Expected Values, but since the ticket has a defined 'game' instance, a single ticket is a gamble. Playing the lottery in the long run could be part of a high risk investment portfolio. [edited for clarity]
