👇👇
The S&P is a
market weighted average.
The biggest companies (TECH) have an outsized weighting on this index
= about 40%.
It does NOT include⭐️
AMZN
GOOG
TSLA or
META because
they are NOT considered ‘TECH’
they are considered
Consumer Discretionary
&
Communications.
IF you were 2
include the 4 CO's above,
then
the percentage weighting is close 2 53%
=
more than 1/2 of the index
thus it's clear
how influential the tech sector
+
these names R
the headline index.
IF
one compares the above 2 the
Equal Weight S&P
(which gives every CO. the same weight vs. the biggest CO.'s having greater influence)
then
the picture become clearer.
Both indexes have the same names, but different ways of measuring,
which can create a little confusion?
