An index is a statistical measure which describes the changes in a p?rtf?li?
?f st?cks ?f a specific sect?r ?f market. It is thus a mathematical ?bject used
by invest?rs and financial managers t? describe and c?mpare specific features ?f
Mr. Charles D?w
created the first index ever in May ?f 1896 and the m?st widely kn?wn until n?w.
N?wadays it is kn?wn as the D?w J?nes Industrial Average1
(ticker symb?l “DJIA”). Since 1896 many ?ther indices have been created f?r
example S&P 100, S&P 500, Nasdaq C?mp?site index etc. ?ther types ?f
indices are capitalisati?n indices2,
fixed inc?me indices3,
residential pr?perty indices4,
and v?latility indices, which are analyzed in detail in the next paragraphs.
1.2 V?latility Indices and the VIX index
indices measure the market’s pr?spect ?f v?latility based ?n the prices ?f ?pti?ns.
The m?st widely used v?latility indices is the VIX index ?f Chicag? B?ard ?pti?n
The VIX index
is m?re ?r less, like the Nasdaq C?mp?site index. Their maj?r difference is
that the VIX measures v?latility, that is the unexpected m?ves either up ?r d?wn
?f an index, and n?t price. The VIX index (v?latility index) was created in
1993 by the CB?E. The index is an instant measure ?f implied market v?latility.
It is calculated by using the mean ?f real time S 500 ?pti?ns (SPX).
first intr?duced the VIX index he had tw? things in mind (R?bert E. Whaley
,2008). The first ?ne was that, the index had t? bec?me a benchmark ?f implied
sh?rt-term (30- days) market v?latility. He als? wanted t? make the c?mparis?n
between the then- current level ?f VIX with the hist?rical ?nes, s? the minute
by minute values were c?mputed using index ?pti?n prices ?f 1986. The ch?ice ?f
this specific date was n?t rand?m. 1987 was the peri?d ?f the w?rst st?ck
market crash since the Great Depressi?n, the w?rst depressi?n that the w?rld
had ever faced until then. This was particularly imp?rtant since invent?rs were
able t? d?cument the level ?f market anxiety during a very difficult peri?d f?r
the ec?n?my. The sec?nd reas?n f?r the creati?n ?f the index was the intenti?n ?f
pr?viding an index which c?uld be used as an underline asset, f?r futures and ?pti?ns
c?ntracts ?n v?latility. The imp?rtance ?f such trading assets was rec?gnized s??n
after they were first launched (futures May 2004 and ?pti?ns February 2006).
