100 THE INVESTMENT TEAM
ment is determined from your Myers-Briggs type; it is not a sepa-
rate evaluation. Here is the formula :If your four letters contain “N” and “T,” then you are a ratio-
nalist (“owl”).
If your four letters contain “N” and “F,” then you are an idealist
(“dolphin”).
If your four letters contain “S” and “P,” then you are an adven-
turer (“fox”).
If your four letters contain “S” and “J,” then you are a guardian
(“lion”).Each Myers-Briggs type will fall into one of these four tem-
peraments. The temperaments go back 2,500 years to the time of
the Greeks, where they were originally named after the gods and
their characteristics. Keirsey took the original material and updated
it to fit the MBTI. Using Keirsey’s temperaments, we can describe
four distinct kinds of investors, with different motivations and
different approaches.
We start with a review of the lions, then discuss the other three
types.The Guardian (SJ): Lions Rule the Kingdom
View of the market: “It’s a battle to be won by patience, precision,
and discipline.”This is the most common temperament in the financial world.
Lions are left-brained. They are precise, practical, motivated, and
efficient. In short, they get the job done. They make excellent gen-
erals and leaders. Their virtues include discipline and stabilizing
influence. They respect tradition and rules. Their strong suit in
investing is discipline and execution. Their investment style is of-
ten technical analysis, rule-oriented and disciplined.
