You are better off looking at defensive stocks that survive in downturns. Walmart is OK for this. Grocery stores, utilities and oil companies do well in downturns (because people continue buying their products).
That's a pretty good suggestion. Large-scale retailers don't often fold over. I've seen someone suggest investing in pharmaceuticals. Which also makes sense since there's always a market for meds. What do you think about Amazon?
I totally agree with what you say about pharmacy, because the need for drugs now is very much and very needed and people will not be able to stop with treatment because the needs are very vital which will be fatal to humans if they stop treatment. but if I know how to sell it seems like I will not buy even if it's profitable because in many developing countries fraud often occurs with the monopoly of drugs. Amazon is also quite interesting because the development of online business is very advanced and continues to grow.
