I'm not aware of any investment banks or brokers issuing derivative products. I've had a chat to one trying to sell this idea but they won't do it anytime soon. Don't think there's enough meat on the bone for them to chew.

Delta hedging for an investor and the issuer are very different concepts. Options are effective methods to conduct this.
You are buying shares and then buying short options thereby sacrificing some % profit so that you don't loose the lot. When the market does move up, you loose your option premium after expiry and then you buy it again.

Delta is the actual relative movement number, shares and options. Say you walked 10 steps and your partner walked 10 steps as well. Delta is 1. You walked 10 steps and your partner walked 5 steps. Delta is 0.5.

I usually aim for neutral lock position when there's an unsure directional volatility, but this is only in the US markets. I've fixed my position irrespective to company specific earnings risk.

We don't have enough liquidity in option market here and is limited to top market cap companies only.
