Investors searching for signals that could help them anticipate market turning points usually rely on economic data, corporate earnings, or technical indicators. But according to one market strategist, another factor may quietly influence investor behavior: the moon.
During the 3rd Market Traders Summit held on March 21, 2026, organized by the Society of Technical Analysts Philippines, Indonesian strategist Gema Goeyardi presented research suggesting that lunar cycles may correlate with turning points in financial markets—including the Philippine Stock Exchange Index.
Goeyardi, founder and CEO of Astronacci International, is known for developing what he calls financial astrology, a framework that combines astronomical cycles with traditional technical analysis tools. His method, known as Astronacci, integrates planetary cycles with Fibonacci analysis to identify potential reversal periods in financial markets.
“Astronacci is astrology and Fibonacci,” Goeyardi explained during his presentation. “The idea is how we combine time and price to improve our trading decisions.”
While the concept may sound unconventional, Goeyardi argues that the theory rests on a simple premise: financial markets ultimately move because of human decisions. If human psychology can be influenced by natural cycles, those cycles may indirectly affect market behavior.
One of the most important cycles he studies is the lunar cycle.
The moon’s gravitational pull affects ocean tides. Because the human body is largely composed of water, Goeyardi suggested that lunar phases may subtly influence biological rhythms and emotions, which in turn may affect investor behavior and decision-making.
“When we talk about markets, we talk about human decisions,” he said. “Human mood and psychology influence whether people buy or sell.”
To test this idea, Goeyardi analyzed historical data from the Philippine market. His research found that full moon and new moon phases coincided with potential market reversal points roughly 79% of the time between 2023 and 2026.
The timing appears most significant within a narrow window around the lunar event itself. According to the data he presented, turning points often occur on the day of the moon phase or within one day before or after it.
For traders, these cycles can provide a potential timing window rather than a guaranteed directional signal.
“If the market is declining and approaching a full moon or new moon, there is a higher probability that the market may soon reverse,” Goeyardi explained.
A Key Turning Point for the Philippine Market
During the summit, Goeyardi identified March 19, 2026 as a “vibrational date” for the Philippine market because it coincides with a new moon cycle, which historically has aligned with reversal points in his analysis.
In his forecast, the Philippine stock market could potentially find support near the 5,879 level before staging a rebound. If the reversal occurs, he suggested the index could eventually move back toward 6,500, with 6,200 serving as a nearer-term recovery target.
However, he emphasized that vibrational dates signal possible turning windows rather than guaranteed market direction. A reversal could mean a shift from decline to rally—or simply a temporary pause before the next move.
These turning windows typically occur within a few days around the planetary cycle, meaning the potential reversal period could fall around March 18 to March 20.
What the Cycles Suggest for Philippine Blue Chips
Goeyardi also applied his timing framework to several major Philippine stocks, highlighting how lunar cycles and planetary alignments may coincide with price reversals.
For SM Investments Corporation, he observed that the stock has historically shown a relationship with lunar cycles. After a recent decline, he suggested the stock could potentially rebound following the March lunar cycle, with a possible upside target around ₱679.
Property developer SM Prime Holdings was also highlighted. Goeyardi noted that the stock appeared to be forming an ABC correction pattern, and if the lunar cycle signals a reversal, the price could move toward ₱22, although a deeper support level around ₱18.8 remains possible.
For banking stocks, Metrobank appeared to be completing a corrective structure that could reverse upward if the cycle holds, with a potential recovery target near ₱71.
He also discussed stocks such as BPI and Aboitiz Power, where price movements around lunar phases could signal short-term turning points even if the broader trend remains sideways.
In several cases, Goeyardi explained that lunar signals should be used together with traditional tools such as support and resistance levels, Fibonacci retracements, and moving averages.
Time and Price
Ultimately, Goeyardi’s framework emphasizes the importance of analyzing both price and time in financial markets.
Most investors focus on price targets—how high or how low a stock may move. But Goeyardi believes identifying when a market may change direction can be just as important.
“Price tells us what the market is doing,” he said. “Time tells us when the market may change.”
Whether financial astrology will gain broader acceptance among professional investors remains an open question. But the research presented at the summit reflects growing curiosity among traders about unconventional ways of analyzing markets.
For investors navigating the ups and downs of the Philippine stock market, even the moon—according to some analysts—may offer a clue about when the next turning point could arrive.
