From an astrological standpoint, predicting the events and fortune of a single company or a line of business, is not that difficult. The stock market, though, is a much more complicated thing.

To use astrology in the analysis of a company, it is necessary to be able to erect a probable horoscope for its birth, or its latest major change of structure or ownership. With that horoscope, analysis and predic­tions are extracted in pretty much the same way as with personal horoscopes.

In predicting the general development of a whole line of business, such as banking, shipping, media or medicine, a horoscope is not needed. Instead, the planetary movements through the zodiac are inter­preted, without the need for a particular starting point to compare them with.
