Stock Market Astrology and Numerology: what traders believe, and what the evidence says
Planetary transits, Mercury retrograde, full moons, lucky numbers and Muhurat timing come up in trading groups every week. This guide explains how each idea is supposed to work, where it came from, and what published research actually found, so you can make up your own mind.

Can astrology or numerology predict the stock market?
The short answer: no reliable study shows that planets, zodiac signs or numbers can forecast the price of a stock or an index like the Nifty 50 or Sensex. A few studies have found a small statistical pattern in returns around new and full moons, and research shows that superstitions about lucky numbers can move prices for a while. Those findings describe how people behave, not a trading system. Astrology and numerology are cultural traditions many Indians respect. They are not a substitute for analysis, risk management or a SEBI-registered adviser.
What is stock market astrology?
Stock market astrology, also called financial astrology or astro-trading, is the practice of linking the positions and movements of the Sun, Moon and planets to price movements in shares, indices, commodities and currencies. Practitioners study planetary transits, retrogrades, eclipses and the angles between planets, then mark dates they expect to bring a trend change, a spike in volatility or a strong move in a particular sector.
In India, most practitioners use Vedic astrology (Jyotish), with its sidereal zodiac, the nine grahas including Rahu and Ketu, and nakshatras. Western financial astrologers use the tropical zodiac and often chart a company’s “birth” from its incorporation date or first day of trading.
Stock market numerology works with numbers instead of planets. It reduces dates, company names, ticker codes and price levels to single digits and gives each digit a meaning. Some numerologists also assign lucky and unlucky days for buying or selling.
A short history of astro-trading
- Ancient rootsBabylonian, Indian and Chinese astrologers tied the sky to harvests, kings and trade long before stock exchanges existed. Commodity and grain traders inherited many of these ideas.
- Early 1900s · W.D. GannThe American trader William Delbert Gann became famous for geometric angles, time cycles and the “Square of Nine”. Later writers argue he also relied on planetary cycles, which keeps Gann at the centre of astro-trading talk today.
- 1948 · The Bradley SiderographDonald A. Bradley published Stock Market Prediction, a “planetary barometer” that scores planetary angles to mark possible turning dates. Charting tools still include it.
- Today · Apps, forums and YouTubeDaily “Nifty astrology” forecasts, Mercury retrograde warnings and numerology-based “lucky stocks” are widely shared online, especially when markets fall sharply.

9 astrology ideas traders talk about, and how they hold up
For each idea you get what practitioners claim and an honest label for the evidence: researched, mixed, no evidence found, or cultural tradition.
-
Planetary transits
The claim: when a planet moves into a new sign, the sectors it “rules” gain or lose strength. Jupiter and Saturn transits are watched most closely because they last for months or years.
No evidence found -
Mercury retrograde
The claim: when Mercury appears to move backwards, about three times a year, communication, contracts and technology go wrong, so markets turn choppy and new trades should wait.
No evidence found -
New moon and full moon
The claim: moods swing with the lunar cycle, so returns are weaker around the full moon and stronger around the new moon. This is the one idea academics have tested seriously.
Researched, mixed -
Solar and lunar eclipses
The claim: eclipses (Grahan) bring sudden reversals and shocks, and some traders avoid opening positions in the days around one.
No evidence found -
Conjunctions and aspects
The claim: the angle between two planets (0°, 90°, 120°, 180°) creates harmony or tension. The Jupiter and Saturn conjunction, roughly every 20 years, is linked to long economic cycles.
No evidence found -
Rahu and Ketu
The claim: in Vedic astrology, the lunar nodes Rahu and Ketu bring speculation, bubbles and sudden loss. Their transit through a sign is read as a signal for risky or defensive sectors.
No evidence found -
Bradley Siderograph
The claim: adding up the planetary angles for each day produces a line whose turning points mark dates when the market may reverse, though not the direction of the move.
No evidence found -
Gann time cycles
The claim: markets repeat in fixed cycles of days, weeks and years (such as 30, 90, 144 and 360), and some of these line up with planetary orbits.
No evidence found -
Muhurat timing
The tradition: starting something at an auspicious muhurat brings prosperity. NSE and BSE hold a special one-hour Muhurat trading session on Diwali to mark the start of the new Samvat year. Many families buy a few shares as a ritual.
Cultural tradition
Which planet “rules” which sector?
Astrologers in India commonly link each of the nine grahas to industries. These pairings come from tradition and vary between practitioners. They have not been shown to predict sector returns.
| Graha (planet) | Sectors astrologers link to it | Traits in tradition |
|---|---|---|
| ☉︎SuryaSun | Government companies (PSUs), power, gold, pharmaceuticals | Authority, leadership, vitality |
| ☾︎ChandraMoon | FMCG, dairy, beverages, silver, shipping | Mind, public mood, liquids |
| ♂︎MangalMars | Defence, steel, real estate, construction, energy | Energy, aggression, land |
| ☿︎BudhMercury | IT, telecom, media, trading and broking | Communication, commerce, intellect |
| ♃︎GuruJupiter | Banking, finance, insurance, education, gold | Wealth, wisdom, expansion |
| ♀︎ShukraVenus | Luxury goods, autos, jewellery, entertainment, textiles | Comfort, beauty, pleasure |
| ♄︎ShaniSaturn | Oil and gas, mining, metals, infrastructure, labour-heavy industries | Discipline, delay, hard work |
| ☊︎RahuNorth node | Technology, aviation, chemicals, speculative and new-age stocks | Obsession, illusion, sudden gains |
| ☋︎KetuSouth node | Research, spirituality-linked businesses, pharma research | Detachment, sudden loss, research |
Notice how broad these lists are. Banking, gold and pharma each appear under more than one planet. With enough overlap, almost any market move can be explained after it happens, which is one reason these links are hard to test.
How numerology is used in trading
Numerology turns dates, names and prices into single digits from 1 to 9 and reads meaning into them. Here are the six methods you will meet most often.
Company “birth number”
Add the digits of a company’s incorporation or listing date until one digit remains. Numerologists then compare it with the date you plan to buy, or with your own birth number, to judge “compatibility”.
Name numerology
Each letter gets a value under the Chaldean or Pythagorean system. The total for a company name or ticker is reduced to a root number. Some businesses change the spelling of their name to reach a “luckier” total.
Lucky and unlucky trading days
Personal numerology charts mark certain dates as good for buying and others for staying away. The same calendar date gives different advice to different people.
Gann’s Square of Nine
A spiral of numbers starting from 1 at the centre, used to project support, resistance and timing levels from a past high or low. It is numeric, not astrological, but it is often taught alongside astro-trading.
Fibonacci levels (often confused with numerology)
Ratios such as 38.2%, 50% and 61.8% are standard technical analysis tools. They come from mathematics, not mysticism. Whether they work is still debated, but they are easy to test on a chart.
Round numbers and “magic” levels
Index levels like a new thousand on the Nifty attract headlines and orders. Research on price clustering shows traders really do place more orders at round numbers. That is human behaviour, not number magic.
What published research actually found
We looked for peer-reviewed studies on each popular claim. Where research exists, here is what it says, in plain words.
Lunar cycle and returns
Small, mixedAcross 48 countries, returns were 3% to 5% a year lower in the days around a full moon than around a new moon. A wider study of 62 indices later found a new-moon effect but no full-moon effect. The suggested cause is mood, not astrology, and the effect is small.
Yuan, Zheng and Zhu, Journal of Empirical Finance, 2006 · Keef and Khaled, Journal of Empirical Finance, 2011Moon phases over 100 years
Small, mixedIn US indices over a century and in 24 other countries over 30 years, returns in the 15 days around new moons were about double those around full moons, with no lunar effect on volume or volatility.
Dichev and Janes, Lunar Cycle Effects in Stock Returns, 2003Lucky numbers in listings
Real, hurt believersIn China, more companies than chance would predict got “lucky” listing codes. Those firms were valued higher just after their IPO, the premium faded within three years, and they later underperformed. Superstition moved prices, then cost the believers.
Hirshleifer, Jian and Zhang, Management Science, 2018Mercury retrograde, transits, eclipses
No evidence foundWe did not find any peer-reviewed study showing these events predict returns. Most claims online come from astrologers’ own track records, which are rarely recorded in advance or checked independently.

Documented behaviourWhen the Sensex fell about 38% in March 2020, Indian investors turned to astrologers and numerologists in larger numbers. One astro-numerologist reported a 25% to 30% jump in client calls.

Why astrology feels like it works in the market
Markets are uncertain, and uncertainty is uncomfortable. These four mental shortcuts make astro and number signals feel more accurate than they are.
- 01
Pattern seeking
Our brains find shapes in random data. With nine planets, twelve signs and hundreds of aspects, some line-up will always appear to match yesterday’s move.
- 02
Confirmation bias
We remember the forecast that came true and forget the five that did not. Vague predictions such as “volatility likely this week” are almost always right.
- 03
Illusion of control
A date, a number or a ritual gives a feeling of control over something we cannot control. That comfort can lead to bigger positions and skipped stop-losses.
- 04
Hindsight stories
After a crash, it is easy to find a planet that “explains” it. Explaining the past after the fact is not the same as predicting the future.
Astro tips, SEBI rules and how to test any claim
In India, anyone who gives specific buy or sell recommendations for a fee must be registered with SEBI as a Research Analyst or Investment Adviser. Calling it astrology does not change that. SEBI has acted against several unregistered “finfluencers” who sold tips through Telegram and social media.
Red flags in paid astro-trading services
- Guaranteed returns or “sure-shot” calls based on planets or numbers.
- Specific stock, option or Nifty level calls with no SEBI registration number shown.
- Screenshots of past wins, but no dated record of every forecast made in advance.
- Pressure to pay for a “remedy”, gemstone or puja before a trade will work.
- Requests for your trading login, OTP or money sent to a personal account.
Before paying anyone for advice, search their name on SEBI’s official list of registered intermediaries at sebi.gov.in.
Test any market claim yourself
- Write the rule down exactly, for example “buy the Nifty on new moon, sell on full moon”.
- Collect at least 10 years of daily prices and the dates the rule refers to.
- Apply the rule to every date, not only the ones that look good. Include brokerage, taxes and slippage.
- Compare the result with simply holding the index over the same period.
- Then test it on a later period you did not look at. A real edge survives data it has never seen.
What actually helps you read the market
If astrology drew you in because you want to know when to act, these skills answer the same question with methods you can test and improve. They are what we teach at 9AM Traders Academy.
Technical analysis
Read price, volume, trends, support and resistance on real charts, and plan entries and exits in advance.
Fundamental analysis
Judge a business from its annual report, cash flows, debt and management, instead of its listing date.
Risk management
Position sizing and stop-losses decide whether one bad call is a lesson or a disaster.
Trading psychology
Keep a journal, spot your own biases and follow a plan when fear or greed takes over.

Stock market astrology and numerology: common questions
Does astrology work in the stock market?
No peer-reviewed study shows that planetary positions, zodiac signs or transits can reliably predict share prices or index levels. A few studies found a small difference in returns between new-moon and full-moon periods, but researchers link it to investor mood, and later studies found it inconsistent.
Can astrology predict the Nifty or Sensex?
Daily Nifty and Sensex astrology forecasts are widely shared, but we found no independent record showing they beat chance when every forecast is counted, not just the ones that came true. Index moves depend on earnings, interest rates, global markets and fund flows.
What is financial astrology?
Financial astrology is the practice of linking the movements of the Sun, Moon and planets to markets. Practitioners chart planetary transits, retrogrades, eclipses and aspects to mark dates they expect to bring turning points or sector strength. In India it usually follows Vedic astrology.
Does Mercury retrograde affect the stock market?
Mercury retrograde is said to bring confusion and failed deals, so some traders avoid new positions during it. We did not find any peer-reviewed study showing that markets behave differently during Mercury retrograde periods.
What is stock market numerology?
Stock market numerology reduces dates, company names, ticker codes and price levels to a single digit and assigns meaning to it. Common methods include a company's birth number from its listing date, name numerology, and personal lucky trading days.
Are lucky numbers useful when picking stocks?
Research on Chinese IPOs found that companies with lucky listing codes were valued higher just after listing, but the premium faded within three years and these companies later underperformed. Believing in lucky numbers moved prices, and believers paid for it.
Which planet is linked to the stock market in Vedic astrology?
Astrologers often link Jupiter (Guru) to banking and finance, Mercury (Budh) to trading and commerce, Saturn (Shani) to oil, metals and infrastructure, and Rahu to speculation. These links come from tradition and vary between astrologers. They have not been shown to predict sector returns.
What is Muhurat trading?
Muhurat trading is a special one-hour session that NSE and BSE hold on Diwali to mark the start of the new Samvat year. Many investors buy a few shares as a ritual for prosperity. It is a cultural tradition, not a forecasting method.
Is it legal to sell astrology-based stock tips in India?
Giving specific buy or sell recommendations for a fee requires SEBI registration as a Research Analyst or Investment Adviser, whatever method is used. Before paying for any tips, check the provider's name on SEBI's list of registered intermediaries.
Is Gann theory the same as astrology?
Not exactly. W.D. Gann's angles and Square of Nine are geometric and numeric tools, but many writers say Gann also used planetary cycles. Both parts are popular in trading circles and neither has strong independent evidence behind it.
