To the uninitiated, derivatives (based on securities) as a segment is meant for sophisticated investors with deep pockets but, even a cursory analysis of the participants in this segment would reveal that over 60% of derivatives’ volume is generated by retail investors and this has been a consistent trend over the past 5 years indicating that there is something in it for small investors too.
The fact that volumes in this segment are typically 3-4 times that of the cash market (equities) further underlies its importance and even if as an investor one shies away from trading in the same, one must keep a keen eye on it to understand market dynamics better.
Derivatives are an essential feature of mature capital markets worldwide, not only do they facilitate price discovery and allocation of risk, their speculative element is also desirable (within limits of course!), since speculators provide necessary liquidity to the market and liquid markets are less prone to sharp fluctuations.
Lower capital requirements and the option of taking both bullish and bearish views make derivatives extremely attractive though understanding their dynamics requires some time and effort. Derivatives in securities can be classified into Futures and Options and this is where the great divide in terms of retail investor interest takes place.
Equity based futures as a class has not only been embraced by retail investors but is being encouraged by market regulators as well. India has the highest number of equities that serve as the underlying for single stock futures. At the same time, regulators and exchanges are trying to increase retail participation in index futures also – by introducing index based futures in small lots. Index futures constitute over 25% of the total turnover in the FnO segment. Volume figures for a typical trading day (May 28, 2008) corroborate this fact:

On the other hand, despite the obvious lure of options (especially for hedging) and the introduction of Index based options, retail participation is very low are perhaps rightly so since historical data suggests that more than 90% of options go unexercised, benefiting the option writer (retail participants cannot write options) who is usually a seasoned trader. To overcome some of these glitches SEBI is contemplating upon introducing long-term options contracts in equities in order to make it easier for retail investors to hedge.
Figures for Index options (May 28, 2008)

The volumes in both futures and options segments indicate that these are highly liquid markets and with increasing activity, retail investors who are yet to explore the same, should not shy away from the derivatives segment and commit a part of their portfolio to this segment to increase their returns from the market.
