Collins said it is unfortunate that companies have decreased their use of equity derivatives because the "underlying exposures are still there". "But usage [of equity derivatives] has gone down and that's bad," said Collins.
Corporates can use equity derivatives to hedge against the risk of having to buy their own shares in the future at a relativley high price.
Collins said corporate scandals have slowed the addition of new corporate derivatives users, while the market downturn has created cashflow uncertainty.
Also, new accounting policies that require the mark-to-market of derivatives share repurchase strategies through the profit and loss statement have also decreased the use of derivatives, said Collins.
"If FASB [the Financial Accounting Standards Board] makes it more complicated for you to look at the financials, then that will reduce the use of derivatives," said Collins. "It will create volatility in the income statement."
FASB is expected to require the mark-to-market of share buy-back strategies in October.
