Well, for starters, the goat is gone. But this Economic Times article by Amit Kapoor & Chirag Yadav sheds a bit more light on why there’s a disconnect between stock market and the economy.
The behavioural aspect of the trend has been recently outlined by Robert Shiller based on his work on how narratives shape economic outcomes. Shiller argues that the initial market resilience in US until mid-February was the lack of familiarity of investors with pandemics as the event had no historical precedent. Moreover, investors had not anticipated the global spread of the disease and the halting of economic activity in response to it at the scale in which we have seen. The following dip was driven by the stories emerging from China and Italy of hospitals having to choose patients and stores running out of essentials. But eventually, when the government swept into action to provide aggressive stimulus, investors found themselves in familiar territory of previous economic crises. The state-led actions reinforced investor belief to return to the markets, which have staged a prompt and promising recovery.
It is later in the article the authors explain the disconnect between capital and real markets over the long run.
The macroeconomic explanation provides a more generalised contextualisation. A prominent change over the last decade has been the excessive liquidity infusion in the global markets driven by the quantitative easing in the developed world, especially US, where interest rates have reached near zero levels. Most of this money has found its way into capital markets for easy returns instead of materialising as real investments. A lot of the money has also flown into the capital markets of developing countries like India. Investors also know that the central banks and government will back their capital with taxpayer money in case of market failure. Thus, capital markets have begun to provide faster and more secure returns than real investments.
