FlightDeck
The platform we needed didn’t exist, so we built it.
Every day FlightDeck classifies the market regime, tracks each period’s alpha, watches the Storm Center and flags when a position needs a human decision. Decisions come from evidence, not from the day’s mood.
First, separate the market from selection
FlightDeck’s Pure Beta / Alpha Opportunity framework, forthcoming in the Journal of Investment Management, asks what kind of day it is. When SPY moves more than 1% in either direction, we classify it as Pure Beta: a day dominated by the market. Moves of 1% or less are Alpha Opportunity days, when differences between stocks make selection easier to measure.
