YORK

(CNNM)

--

AstraZeneca's

stock

tumbled

Monday

after

the

company

said

it

would

pay

$15

billion

to

acquire

MedImmune,

a

deal

that

some

industry

analysts

are

calling

too

expensive,

and

risky.

The

deal's

near-term

benefit

is

limited,

analysts

say,

but

they

believe

the

deal

may

make

AstraZeneca

more

competitive

in

the

fast-growing

biotech

sector

in

years

to

come.

"The

rumor

of

MEDI

being

bought

has

been

in

the

market

for

several

weeks,

but

there

was

little

expectation

that

the

deal

would

be

as

big

as

it

is,"

wrote

Hamed

Khorsand,

analyst

for

BWS

Financial,

in

a

published

note.

AstraZeneca's

stock

slid

5

percent

following

the

announcement

while

MedImmune's

stock

surged

18

percent.

That's

on

top

of

MedImmune's

14

percent

stock

gain

on

April

12,

when

the

company

said

it

was
