What are examples of inversely (negatively) correlated stock prices in economics? I’m looking for example of two goods/wealth that demonstrate inverse/negative correlation. For example if price of A rises then price of B falls. May be it is oil or gold prices along with some other wealth. Or may be some share prices (stocks) of some two companies. I can’t find example of such negatively correlated prices data.
Have you tried Google? By copying a part of your question into Google I was able to find several examples. The best one may be this site which lists 20 positively and negatively correlated stocks for any stock you pick:
