SELECTINGINVESTMENTSINAGLOBALMARKET

AnswerstoOuestions

1.Themajoradvantageofinvestingincommonstocksisthatgenerallyaninvestorwould

earnahigherrateofreturnthanoncorporatebonds.Also,whilethereturnonbondsis

pre-specifiedandfixed,thereturnoncommonstockscanbesubstantiallyhigherifthe

investorcanpicka“winner"-i.e.,ifthecompany'sperformanceturnsouttobebetter

thancurrentmarketexpectations.Themaindisadvantageofcommonstockownershipis

thehigherrisk.Whiletheincomeonbondsiscertain(exceptintheextremecaseof

bankruptcy),thereturnonstockswillvarydependinguponthefutureperformanceofthe

companyandcouldwellbenegative.

2.Thethreefactorsare:

(1)LimitingoneselftotheU.S.securitiesmarketwouldimplyeffectivelyignoringmore

than50%oftheworldsecuritiesmarket.WhileU.S.marketsarestillthelargest

singlesector,foreignmarketshavebeengrowinginabsoluteandrelativesizesince

1969.

(2)Theratesofreturnavailableonnon-U.S.securitiesoftenhavesubstantiallyexceeded

thoseofU.S.securities.

(3)Diversificationwithforeignsecuritiesreducesportfoliorisk.

3.Internationaldiversificationreducesportfolioriskbecauseofthelowcorrelationof

returnsamongthesecuritiesfromdifferentcountries.Thisisduetodiffering

internationaltradepatterns,economicgrowth,fiscalpolicies,andmonetarypolicies

amongcountries.

4.TherearedifferentcorrelationsofreturnsbetweensecuritiesfromtheU.S.andalternate

countriesbecausetherearesubstantialdifferencesintheeconomiesofthevarious

countries(atagiventime)intermsofinflation,internationaltrade,monetaryandfiscal

policiesandeconomicgrowth.

5.ThecorrelationsbetweenU.S.stocksandstocksfordifferentcountriesshouldchange

overtimebecauseeachcountryhasafairlyindependentsetofeconomicpolicies.

Factorsinfluencingthecorrelationsincludeinternationaltrade,economicgrowth,fiscal

policyandmonetarypolicy.Achangeinanyofthesevariableswillcauseachangein

9.Unlikecorporatebonds,interestonmunicipalbondsisexemptfromtaxationbythe

federalgovernmentandbythestatethatissuedthebond,providedtheinvestorisa

bondwithaninterestrateof8percentyieldsanetreturnaftertaxesofonly5.20percent

[.08x(1-.35)].Atax-freebondwitha6percentyieldwouldbepreferable.

10.Theconvertiblebondofthegrowthcompanywouldhavetheloweryield.Thisis

intuitivebecausethereisagreaterpotentialforthepriceofthegrowthcompanystockto

Thus,theinvestorwouldbewillingtotradeoffthehigherupsidepotentialresultingfrom
