It would be interesting to know what exactly constitutes a good economy. There are many publications on this and all have different, sometimes biased perspectives.
I think the main measurement is Employment and Jobs, then CPI, Exports vs imports,Debt and of course there may be a lot of others, but Jobs is really the most important. So we have low unemployment therefore the economy is generally good. CPI and Debt are dampeners but jobs are key.
I personally think that the stock market is a poor measurement, and one that gets way more stock (Pun intended) that it deserves. Why? Because for the most part it is based on emotion and/or automation (Algorithms). OK yes if a company is doing well, it's stock price will be bought up, but it can easily go down if traders want to take profits just because they feel like it. If there is a disaster or something abroad that causes the SM to crash, the overall economy still could remain very good if the majority is employed.
Not sure why I am rambling on about this, but I generally think too much is put into the health of the stock market. Also interest rates could be high, and unemployment could be very low, the economy would still remain good.
