If you really want to speculate, buy a call option on KO.
For the Jan 21, 2022 expiration date, you could buy the call with a $50 strike (about what it is today) for about $6.10. This gives you the option, but not the obligation, to buy KO up until that date. And instead of putting $50 at risk, you're putting $6.10 at risk. So for the same investment amount, you could have 9x the leverage (although your risk of total loss would be much higher if you levered that high).
If KO goes from $50 to $60 as you think it will, that option will be worth $10 in Jan 2022, a 64% gain instead of the 23.5% gain you'd get from the stock, dividends included. You could actually earn more than that if, for example, KO gets to $60 in only a few months and there is lots of time value remaining on the option.
But if KO hangs out at $49 for a year - you'd lose 100% of your investment instead of 2%.
