Any events that impacts the economy impacts the stock market.
The value of stocks can be affected by a variety of reasons. It can
be highly volatile due to complex reasons. Some of the factors
directly impact the stock market and some other indirectly. For
eg:
- In the aftermath of the 2001 Sept 11 terrorist attacks, the
world has become cautious due to fear. Global investors started
pulling out many of their investments due to the volatility and
traders started looking for shorting opportunities. As a result,
the indices crashed a bit. World events such as war, terrorism,
civil unrest, etc can seriously impact the value.It can be termed
as an direct impact.
- When Coronavirus impacted the globe as a pandemic, without any
skips, the whole world markets crashed heavily due to the fear of
the virus and the imposition of lockdowns across countries. It took
more than a month to recover from the steep fall and it still seems
volatile due to the rising cases of Coronavirus across the
globe.
- When there is a major political change happening a P5 country
like United States, there will be impact in the economies worldwide
as US Dollar is an internationally accepted medium for exchange and
any impact Dollar has will have wide impacts on the whole world.
Exchange rates will fall and debt will be restructured and trade
will get affected.
- When Brexit vote happened and subsequently resignation of David
Cameron happened, markets plunged worldwide due to the uncertainty
that followed about the future of UK..
Likewise, every news that has a value globally will impact stock
markets as stock markets are a leading indicator of economy.
