Hello,
I know this is almost going to be a rehash of my other post (https://www.quantopian.com/posts/isolating-specific-returns), but I've tried what I did to isolate the specific returns and it hasn't worked.
As you can see the Volatility Common Returns are pretty spectacular. Do you have any suggestions for how I could isolate them?
I've used the Risk Model as below
neutralize_risk_factors = opt.experimental.RiskModelExposure(
risk_model_loadings=risk_loadings,
version=opt.Newest,
min_momentum = -0.001,
max_momentum = 0.001,
min_size = -0.1,
max_size = 0.1,
max_volatility = 0.4,
min_volatility = -0.4,
max_short_term_reversal = 0.001,
min_short_term_reversal = -0.001,
min_value = -0.001,
max_value = 0.001,
)
It's had very limited effect, it did however increase Volatility Based Common Returns.
What I am wondering is if there is a way to get the factor exposures of specific stocks inside your portfolio in order to attempt to hedge inside your algorithm?
i.e.
size_exposure = get_factor_exposure(sid(24)).size()
Or something to that effect, is that possible?
You can add a column to the pipeline for any of the common factors. See the help, eg “class ShortTermReversal”
Hi @Quant Trader,
Here's a simple example of a Pipeline that gets the Volatility factor exposure, along with close price.
