?ff?ctiv? mark?tplac? th?ory r?main?d major pr?s?nt?d using Markowitz now day 1952 in was nam?d by fama
in th? y?ar 1970 which assum?d that th? financial mark?t includ? all
information r?garding th? public and ass?rt th? shar? pric?s show all information
that is r?l?vant to it. In th? fi?ld of financ? a lot of ?mphasis is th?r? on
incr?as? is still ?vid?nt th?r? in substantial anomali?s in financial mark?ts.
It shows that th? principl? of rational b?haviour on ?MH may b? fail?d r?s?arch?rs
hav? tak?n k??n int?r?st in this ar?a and th?y ar? looking for and working to
includ? human b?haviour and its impact on this th?ory. According to th? r?c?nt
th?ory th? pr?s?nt assumption hav? b??n prov?d inconsist?nt of th? individual b?haviour.
Thus th? anomali?s of th? r?c?nt portfolio mod?ls hav? mad? th? d?v?lopm?nt
proc?ss much fast?r what is call?d b?havioural financ?. Th? b?havioural financ?
lit?ratur? can b? dividing into two typ?s, th? id?ntification of anomali?s th? ?ffici?nt
mark?t hypoth?sis that b?haviour mod?ls may ?xplain and th? id?ntification of undivid?d
inv?stors b?haviours or bias?d old ?conomic th?ori?s of inconsist?ncy in
rational b?haviour. B?havioural financ? thus chall?ng?s th? ?ffici?nt mark?t
point of vi?w that how th? inv?stors p?rc?iv? th? alr?ady availabl?
information. It prov?s h?lpful in und?rstanding th? prioriti?s of individual’s
inv?stors. It h?lps th? inv?stors to think pragmatically and mak? d?cision
proving fruitful for th?ir busin?ss.
th? b?haviours financ? as th? study of th? influ?nc? of psychology on th? b?haviour
of financ? practition?rs and th? subs?qu?nt ?ff?ct on mark?ts. B?haviour financ?
aims at finding th? r?asons how and why th? mark?t is in ?ffici?nt and this mak?s
r?s?arch?r barb??rs and thaalor hav? d?scrib?d b?havioural financ? r?s?arch in
th? following way ”w? hav? now b?gin th? importanc? job of trying to docum?nt
and und?rstand how inv?stors both amat?urs and prof?ssionals mak? th?ir
portfolio choic?s until r?c?ntly such r?s?arch was notably abs?nt from th? r?p?rtoir?
of financial ?conomists p?rhaps b?caus? of th? mistak?n b?li?f that ass?ts
pricing can b? mod?ll?d without knowing anything about th? b?haviour of th? ag?nt

pap?r puts forth a qu?stion what can b? l?arnt by studying b?haviour financ??
In ord?r to ask such qu?stion this r?s?arch pap?r r?vi?ws th? ?ffici?ncy of
mark?t hypoth?sis th?ory and th?n ?xplains th? prosp?ct th?ory. Th? oth?r s?ction
shows diff?r?nt psychological and sociological principl?s that consist of th?
basics of th? b?havioural financ?.
?ffici?nt mark?t hypoth?sis foundation and limits standard financ? is th? body

th? portfolio principl? of Markowitz th? portfolio principl?s of Markowitz th?
capital ass?t pricing th?ory of sharps and th? option pricing th?ory of black Schol?s
