How to turn an FDA-calendar sample into a testable bio-runup procedure

A sample is not a slogan

A one-year FDA calendar can be written as a mechanical trading system rather than as a rumor. The editorial aim of this archive note is to show that sequence: define the holding window, exclude the announcement day, compare alternative lookbacks, and only then decide whether a bio-runup rule is even tradable.

The archive facts describe a historical workflow. They do not, by themselves, say that a rumor-runup rule belongs on a live desk.

How the 2010 sample was built

The 2010 FDA-calendar sample contained 59 panel or PDUFA runups. The study concentrated on companies valued under $1 billion. That small-cap-filter was applied so larger names would not improve the reported averages.

Each runup was measured over two months of trading data, specified as 44 trading days, to limit holiday interference in the window.

Compare the holding windows first

Among the compared holding windows, the raw-except-five-days method showed the strongest average result in the panel-date table. That window is long from two months before the FDA panel date until five days before it. The table reported a 13.29% return with 4.89% average risk.

The same panel-date table reported much weaker averages for the other windows. The unfiltered raw position showed a 2.55% return with 5.10% average risk. The six-week-prior window showed a -0.26% return with 1.84% average risk. The four-week-prior window showed a -1.82% return with 0.93% average risk.

Editorial reading: the comparison is the decision point. A rumor-runup idea is not treated as tradable until the alternative lookbacks have been placed on the same table.

Exit before the announcement

The intended procedure is to participate in the pre-decision speculative rally and exit before the FDA announcement rather than hold through the binary decision itself. In this design, a pdufa-date or panel date ends the pre-announcement holding period. The announcement day is not part of the trade.

That is why the holding window is specified before any live-desk reading is allowed. Entry, exit, and abstention from the binary day are one procedure.

Optimize the signals, then paper-trade them

A companion software environment can display prebuilt or custom strategy signals on a list, map, or chart. Version 8.0 applies dynamic strategy and time-frame optimization to those signals.

The same environment includes playback and a paper-brokerage-simulator whose account settings can match a live desk. A candidate rule can be stepped through historical data before it is treated as a live procedure.
