Is buying a lottery ticket considered an investment? 
This question feels like an EL&U question to me, and so I will treat it as one. Investment, noun form of to invest, originally from the Latin investire, meaning to clothe, means: [T]o commit (money) in order to earn a financial return Merriam-Webster Online Dictionary, Invest, vb. tr., definition 1 As such, when a person commits money with the purpose of earning a financial return, they are investing.  Playing the lottery, when done so for the purpose of financial return, would fall under this definition - even if it's a poor choice.   Gambling, verb tense of to gamble, likely originally from the word gamen, meaning to play, means: a :  to play a game for money or property b :  to bet on an uncertain outcome Merriam-Webster Online Dictionary, Gamble, vb. itr., definition 1 Playing the lottery is clearly gambling (as a lottery is a game, by definition). The second definition could well include investing in the stock market, particularly certain kinds of investments (derivatives, currency speculation, for example). Aside from the definitions, however, normal usage clearly favors investment to be something with an expectation of positive return, while gambling is taking a risk without that expectation (rather with the hope of positive return).  Legally, as well, playing the lottery is not something that is considered investment (so it is taxed differently).  However, the question was "Can", and by definition, clearly it can be (assuming you are not asking legally).
