EVERYONE from governors of the World Bank to politicians looking for a platform have raised questions about the impact of derivatives products on markets.
This week it was Hong Kong's turn to be assailed by the views of the expert, and not-so-expert, thanks to the decision announced on Tuesday that the Hong Kong Futures Exchange was to commence trading contracts on stocks of HSBC and Hongkong Telecom.
Rafts of brokers, not previously well-known for their research into delta trading, volatility (implied and historical) and the arcane mathematics of risk, suddenly popped up to warn of the deadly dangers posed by stock futures.
They claim that stock futures will lead to massive increases in volatility for the underlying stocks.
A quick glance at the graph above will show this is not supported by evidence. A contract in National Australian Bank shares has traded on the Sydney Futures Exchange since May 19.
Volatility has emphatically not increased.
And David Archibald, who has researched Broken Hill Proprietary - another May 19 futures launch - for five years at James Capel, said the futures contract was a non-issue.
