Timing is tough. If HNZ does what is expected, it may already be as low as it's going to go.
Earnings will be announced Nov. 19. HNZ has already said this will likely be the worst quarter of the year. That could translate into a brief dip in the stock price.
You might want to keep an eye on the price around that date. Otherwise, LeftyMd offers some good advice. Dollar cost average your way into a position before the end of December so you can capture the Jan 10 dividend.
Another strategy is to write (sell) some Dec 48 Puts. The Dec Puts expire a few days before the ex-div date, so if the price is below $48 then, you will own the shares at a price lower than it is trading now. If the price is higher than $48, the premium from the Put will lower your basis. And even if you don't buy the shares (if they are too high), you will still pocket the premium, currently worth about $.75/share.
