In conclusion we can say that volatility is a feature of the equity market. Most people do not like volatility hence avoid being long term equity investors. Therefore, equity returns are better in the long-term. If volatility in the equity markets decreases, then it will attract more investors and capital thus reducing the overall return to investors.

Equities give better returns to investors is because of their volatility not despite their volatility.
