Ratio Backspreads, another way to benefit from a self financing option strategy.
We saw that Ratio Spreads were strategies using options with different strikes, in order to make a profit from a directional move.

Here is another way to make profits from a self financing strategy : the ratio backspreads.



I - Definition

Ratio backspreads are strategies using options
- on the same underlying asset,
- with the same maturity
- with different strikes

And where 'Out of The Money' options are bought and the others are sold.



II - Examples

Using an asset which is worth $100, maturity is set for 180 days it could be built as :
Using calls,
- selling 10 calls struck at 90 / buying 20 calls struck at 115
- selling 13 calls struck at 85 / buying 30 calls struck at 90
- selling 5 calls struck at 105 / buying 8 calls struck at 120

Using puts,
- Selling 10 puts struck at 120 / buying 22 puts struck at 80
- selling 33 puts struck at 85 / buying 50 puts struck at 75
- selling 25 puts struck at 110 / buying 38 puts struck at 105



III - A Self Financed Strategy

As far as we remain within the "ratio" framework, it's needed to make sure that the strategy is a self financing one.

Amount perceived from sold options have to be much larger that those which have been bought.
