Astrology-Based Trading
Timing trades by planetary alignments, lunar phases and astrological cycles.
No scientific or financial-economic basis and no credible out-of-sample evidence of a tradeable edge.
- Why it fails
- There is no scientific or financial-economic mechanism linking planetary positions to asset prices, and no credible out-of-sample evidence that astrological timing predicts returns after costs.
Financial astrology times entries and exits by celestial events — planetary alignments, lunar phases, and longer astrological cycles. It has a long history in market folklore and a steady following.
Assessed on the evidence, the position is straightforward. There is no scientific or financial-economic mechanism that would connect the position of planets to the price of a currency pair or an index, and there is no credible out-of-sample record showing that astrological timing predicts returns after costs.
A statistical caution matters here too. The sky offers a very large number of bodies, aspects and cycle lengths. Test enough of them against price history and some will appear to “work” purely by chance — the same data-snooping problem that Sullivan, Timmermann & White (1999) showed can manufacture impressive-looking but spurious trading rules. Broad reviews of technical methods, such as Park & Irwin (2007), find no robust cost-adjusted edge for approaches of this type.
Stated narrowly and without mockery: the burden of proof rests with whoever claims an astrological edge, and that proof has not been produced. For a real account after costs, there is no validated signal to trade.

Frequently asked
Does astrology-based trading work in 2026?
There is no scientific or financial-economic basis for it and no credible out-of-sample evidence that planetary alignments or lunar phases predict asset returns after costs. The burden of proof is on anyone claiming such an edge, and that proof does not exist in the peer-reviewed literature. Apparent past correlations are consistent with chance given how many bodies, aspects and cycles can be tested.
Is planetary or lunar trading profitable?
No published study demonstrates a profitable, out-of-sample astrological trading system after realistic costs. With a large number of celestial cycles available to test, some will line up with past price moves by chance; that is a data-snooping artifact, not a predictive signal. There is no proposed mechanism by which planetary position would set market prices.
Not investment advice — your mileage may vary, but the burden of proof is on the person claiming an edge. This entry describes general research and published evidence (or its absence), not a recommendation. See the full disclaimer.
