Answer:
The answer is: You would expect a lower stock price.
Step-by-step explanation:
Since John Deere´s main business is manufacturing and selling farming equipment you would expect its sales to rise when farmers are having a successful business year. But when farmers are having a very harsh and bad economic year then you would also expect John Deere´s sales to fall.
If your clients are suffering from a drought that means they will probably lose money or in a best case scenario earn a smaller profit. So they will have less money to invest in new equipment which results in lower sales for companies like John Deere. If John Deere´s sales are lower, they themselves will have a bad economic year so it is logical to assume that their stock price will fall.
