If you’ve ever felt off during a full moon, you’re not imagining it. The moon influences human emotions, behavior, and even financial decisions. And since markets are driven by people, some traders believe moon phases can impact stock prices, volatility, and investor sentiment.
Sounds wild? Maybe. But studies suggest there’s a link between lunar cycles and market trends. Even some hedge funds and professional traders track the moon to time their moves.
So, does the full moon cause market volatility? Can a new moon spark a rally? And most importantly—how can traders use this to their advantage? Let’s break it all down.
How the Moon Affects Market Sentiment
Financial markets are not just numbers—they’re a reflection of human emotions. Fear, greed, optimism, and panic all play a role in stock movements.
Now, consider this:
- The moon controls the tides, affecting over 70% of Earth’s surface.
- The human body is 60% water—so why wouldn’t we be influenced too?
- Studies show the moon impacts mood, sleep, and decision-making.
If the moon affects human psychology, and psychology moves the markets, then lunar cycles could be an overlooked trading tool.
Moon Phases and Market Behavior: What the Data Says
There’s actual research behind this.
📈 The New Moon Effect
A 2003 University of Michigan study found that stock markets tend to perform better in the days following a new moon. Investors are more optimistic and willing to take risks.
📉 The Full Moon Volatility Theory
A 2017 Journal of Empirical Finance study found that market volatility spikes around full moons. Investors are more emotional, leading to irrational trading decisions.
🔄 Hedge Funds and Moon Cycles
Some alternative investment funds factor in lunar cycles when making trading decisions. While they don’t rely on astrology alone, they see it as an additional risk indicator.
The takeaway?
- New moons = Higher confidence, potential rallies
- Full moons = Increased volatility, emotional trading
Breaking Down Each Moon Phase for Traders
Let’s go deeper into how each phase of the moon can impact markets.

How to Use Moon Phases in Your Trading Strategy
If you’re interested in testing lunar cycles in your trading, here’s how to do it:
1. Track the Moon Cycles
Use an astrology or moon phase calendar and mark new moons and full moons on your charts.
2. Cross-Check With Market Trends
- If a full moon lines up with other bearish signals (high RSI, weak fundamentals, bad news), it could mean a sell-off is coming.
- If a new moon aligns with strong technical indicators (breakouts, positive sentiment, bullish news), it might be a good buying opportunity.
3. Use It As a Confirmation Tool, Not a Primary Indicator
Moon phases should be used with technical and fundamental analysis, not in isolation. Consider it an extra edge, just like seasonality or economic cycles.
Final Verdict: Can You Really Trade With the Moon?
Financial astrology might sound unconventional, but the data suggests there’s a correlation between moon phases and market behavior.
Markets are driven by emotion, psychology, and cycles. And if the moon influences human behavior, it makes sense that it could impact trading.
Does this mean every full moon will cause a crash? No. But if you see a full moon aligning with other bearish indicators, it might be time to play defense.
Big institutions are already using alternative data—so why not keep an eye on the moon, too?
Before your next trade, check the sky. The market might just be moving with the moon.
