Hello All,

This morning (Dec 11th, 2018) we received a smaller daily update than normal of only 800 stocks (vs 8000). This caused the US equity-universe selection to only operate on a subset of the full universe. We have alerted the vendors to their corrupted data and are working with them to ensure it doesn't happen again.

We've also built in a redundant coarse-universe data-set based on a second equity vendor which we'll use as a back up if this happens in the future.

Sorry for the inconvenience. A data outage like this is incredibly rare for the platform but it's a high impact event so we'll continue working to ensure they never happen.
