Anyone who says that the stock market isn't an indicator of the economy is plain stupid. I'd rather say that it's a leading indicator in fact which tells that Pakistan is going to do well in times to come. Well done Shahbaz Sharif
Have you even read the tweet? Stock market tends to build any anticipated macroeconomic numbers, good or bad, in advance in its valuations. This is why it is called a lead indicator of economy. Some are laggard indicators such as employment, corporate earnings etc.
