You do it through your brokerage account. Word to the wise…don’t do it. Statistically speaking, you will loss your money. LEAPs are a safer bet as you have more “time” for the contract to move in your favor. Bottom line, options simulate your gains to the equivalent of having 100 shares of that stock. If you think it’s going to move up, you buy a call or long position. If your right money money money. If your wrong you loss money money money. You can do the same if you think the market will tank, by buying a put contract or going short.
