How can be translated the sentence "you have both a long position, and short position, of 200 shares of Microsoft"? "Hai sia una posizione attiva che una posizione passiva di 200 azioni di Microsoft"..I cannot understand exactly the meaning...
This has to do with stock shares. A "long position" means shares held in expectation that the stock price will rise. A "short position" means you borrow shares from someone (while paying fees of course) and will return them later at an agreed time. If the stock shares go down then you buy cheaper ones to repay with. In other words, to sell short (take a "short position") is to make money on falling stock prices. Of course if the stock rises...disastro!!
