If you had to pick one defensive stock to own, which one would you pick out of these?

Anyone?

Johnson and Johnson, as its already a well established brand and its in an area where most people wouldn't cheap out, their children's health and it expands in to more than one area within health and care meaning its customer outlet can expand between all ages where as brands such as Durex are tailored to a more specific audience. Furthermore, I think the average human will buy more shampoo in a regular week that condoms so its more stable. One other point is that there isn't much revolutionary work to be done with shampoo whereas if a competing brand like Trojan developed a more stronger and better condom then sales might deplete for Durex. Overall, J&J seems a lot more stable as its a much more secure investment, unfortunately though the thing is there's not a lot of money to be made investing in these companies anymore as they have already reached their peak and are just in a plateauing state.

That's for that advice. J&J was looking to be my favourite, but I always worry about the GBPUSD exchange rate. Apparently Yelen will raise the base rate, so that should in theory strengthen the dollar (which is good for me). It's just the pound has devalued so much against the dollar, any kind of strengthening of the pound will screw me over (10-15% loss).

Yeah these stocks are consumer defensives for a reason, boom or bust, they will slowly trudge along. It's more of a "safe" place to park my money. Like I know that these stocks will most probably take 6-7 years to double my money, but it's the safety I am seeking. Though bonds might become more attractive in 3-4 years time, when interest rates are at more normal levels.

Reckitt Benckisser (R&B) have great margin I feel still. They can sell a pack of 12 condoms for £12 and people aren't going to take the "cheaper" option in condoms knowing the risks. I just don't see the same profit margin with J&J.
