Binary Option

  

Categories: Derivatives

If you’re a gambling (wo)man, binary options might be the dart throw 'investment' option for you.

When you buy a binary option contract, you’re betting that some type of investment will hit a certain price by a certain date in time. For instance, you can bet that the price of gold will rise by x-amount by y-date. If you’re right, you can gain big bucks (sorry, not the gold itself), likely more so than through normal investments. If you’re wrong, you’re left with nothing but a slimmer wallet.

The “binary” in “binary options” is because it’s an all-or-nothing (betting) game.
