Selene Prime Capital
The MOONX Strategy™ · Est. on a full moon

The market follows the moon.
We follow both.

A systematic, emotion‑free equity strategy that unites three of nature's oldest truths: random selection beats human judgment, the lunar cycle governs behavior on Earth, and prime numbers appear wherever deep order hides. Twenty years of data. Two parameters. One result.

The science of not thinking

Natural selection

Academic finance has known since Malkiel (1973) that a blindfolded monkey throwing darts at the stock pages performs as well as professional fund managers — usually better, after fees. Our selection engine is the monkey, perfected: pure randomness, zero ego, zero fear, zero CNBC. It cannot panic‑sell, because it cannot panic.

Celestial mechanics

The moon moves oceans. Emergency rooms staff up for the full moon; sleep studies show we rest differently under it. Is it so hard to believe that a market made of humans breathes with the same tide? We rebalance exactly at full moon — and the data (below) confirms the theory with remarkable precision.

Prime numbers

Cicadas emerge on prime‑numbered cycles to evade predators. Cryptography rests on primes. They surface wherever deep structure hides — including, our research finds, in the calendar of full moons. We trade only when the full moon falls on a prime‑numbered day. Why does it work? Nobody fully understands primes. That's the point.

We tested every other day. The full moon won.

Skeptics ask: why rebalance at the full moon and not, say, three days after? We swept the entire lunar cycle in 8‑hour increments — 91 separate 20‑year backtests. The optimum sits precisely where theory predicts it: day zero. If this were random noise, would the peak land exactly on the full moon?

Too simple to overfit

Quantitative funds tune hundreds of parameters until the backtest gleams — then wonder why live returns don't. The MOONX Strategy has exactly two calibration constants (7173Why 7173 was inevitableThe concatenation of the twin primes 71 • 73 — a syzygy in number space. Digit sum 18: the eighteenth Major Arcana is The Moon. Factors as 3² × 797, a palindromic prime — symmetric about its center, as the lunar cycle is symmetric about fullness. And 7173 days ≈ 19.6 years, a whisper from the 19‑year Metonic cycle, after which every full moon returns to its calendar date. Discovered, not chosen. and 6980Why 6980 was inevitableDigits 6, 9, 8, 0 — not a single prime among them: the composite counterweight to 7173’s prime‑laden digits. Yet its digit sum is 23, and 797 (the soul of 7173) also sums to 23 — the same signature hidden in both constants. Their difference, 193, is prime, with digit sum 13: the full moons of a blue‑moon year. Their sum, 14153, is prime. Two monkeys, indivisible. — hover over them to see why they were inevitable). Two knobs. What could we even overfit?

Four out of four five‑year windows positive. While 2008 erased half of most portfolios, the lunar calendar kept compounding at 39% a year. The moon and our monkeys do not read the news.

Capacity is limited by the lunar cycle

We accept new capital only at full moons falling on prime-numbered days — roughly four windows per year.
