Does Gold Love Bad News? Hedging and Safe Haven of Gold Agains socks and Bonds SAMA ASHOU ABSTACT This paper examines he conemporaneous and dynamic relaion beween gold excess reurns and he socks and corporae bonds excess reurns. The resuls show ha gold can be used as a hedge and safe haven agains bonds and socks. This paper is he firs o use CAPM and Fama French hree facor models o check he relaion beween gold marke and he sock marke as well as corporae bond marke. Over he enire sample period from 1986 o 2012 here is a significan relaion beween gold excess reurns and marke excess reurns as well as he corporae bonds excess reurns even afer conrolling for Fama French hree risk facors. Addiionally during exreme marke condiions such as crashes and crises here is a negaive relaion beween sock reurns and gold reurns in crashes imes and here is a zero correlaion beween sock and bonds reurns and gold reurns in crises imes and consequenly gold can be used as a hedge agains socks and bonds in he ension imes. The dynamic relaion beween hree markes using VA and IF indicaes ha gold can be used as a safe haven agains socks and bonds. I. Inroducion Gold is a well-known as a precious meal and sore of value for hundreds of decades. Gold is sill he mos famous precious meal for invesmen purposes since many people ransfer heir invesmens from he sock and corporae bonds o miigae heir losses in hese risky markes during he recession periods especially during crashes and crises. Gold rading and prices seing are similar o sock rading. The purpose of his sudy is o invesigae he role of gold as a safe haven or hedge agains losses in financial markes hrough he equiy marke and corporae bond marke by using recen daa and by applying CAPM and Fama French hree facor models o examine he saic relaion beween socks reurns and gold reurns and using vecor auoregressive model (VA) and impulse response funcion (IF) o invesigae he dynamic relaion beween he hree 1
markes. In paricular I examine he iner-relaionships beween hree differen markes gold marke sock marke and bond marke over he period from 1986 o 2012 and during he bad saes of he economy and exreme marke performance especially in financial crashes such as 1987 Sock Marke crash (Black Monday) Sepember eleven crash in 2001 as well as he mos recen crises (Asian crisis 1997-1998 and he global housing crisis (2007-2009). The conribuion of his sudy is wofold. Firs unlike Baur and Lucey (2010) ha examine he relaion beween hree markes using GACH and using daa from 1995 o 2006 and find ha gold canno be hedge agains bonds I used more recen and comprehensive daa and he mos imporan asse pricing models (CAPM and Fama French hree facor models) and I find a significan negaive relaion beween bonds and gold. Second unlike he exising lieraure ha examines eiher he relaion beween gold prices and sock prices (e.g. Baur and Lucey 2010 and Baur and McDermo 2011) or beween gold prices and exchange raes (e.g. Capie Mills and Wood 2005) or even invesigae he riskiness of he gold (McCown e.al. 2006) his sudy aemps o link many sreams of lieraure by examining he co-movemens beween he gold reurns sock reurns and bond yields using differen models. Third his aricle is he firs aemp o use CAPM and Fama French hree facor models o know he saic relaion beween gold socks and bonds. Moreover his is he firs sudy o vecor auoregressive model (VA) and impulse response funcion (IF) o examine he marke inerdependencies and he dynamic relaion beween he hree classes of asses during bad saes of he economy wheher in financial crashes or financial crises. A relaively lile research has been done in his area. My argumen is ha he dependence srucure beween he hree markes is no consan and i may be differen beween normal and calm periods. Mos invesors realized grea losses especially in he las financial crisis because of he significan drop in he sock prices and he experienced subsanial losses 2
due o his phenomenon. This paper ries o provide a suggesion for invesors o include gold in heir invesmen porfolios especially if gold commove agains boh socks and bonds. I find ha he negaive relaion beween socks and gold is sronger and more economically and saisically significan han he negaive relaion beween bonds and gold. To verify ha hese resuls are no spurious I used differen models o conrol for Fama French hree facor models; SMB which is he difference beween reurns on he small firms and he reurns on he large firms HML he difference beween he high book o marke reurns and low book o marke reurns. Addiionally o know he dynamic relaion beween hree markes I used he lagged reurns of he hree markes and run vecor auoregressive regression o make sure ha he resuls are no spurious due o auocorrelaion or he endogeniy problem and o ge he linkage beween hree markes assuming every ime ha each of hem is dependen variables and i is lagged variable as well as he oher wo markes in heir lagged forms are explanaory variables o his marke reurn. There is an imporan sudy in his area by Baur and McDermo (2011) bu hey resric his sudy o gold and socks bu my paper will invesigae he inerrelaionship beween hese hree variables. Moreover Baur and Lucy (2010) use index reurns daa only o represen socks and hey did no conrol for any variables and hey did no use subsamples o check he robusness of he safe haven finding. However my sudy uses a novel daa se in his area of lieraure. My sudy is disinguished by using he value weighed porfolio of all NYSE NASDAQ and AMEX from CSP as well as using S&P 500 from CSP afer comparing i wih FED o correc for missing observaion. Addiionally Baur and Lucy (2006) uses MSCI bond index bu I used boh AAA bonds and BAA bonds from Moody s service by using FED websie. The resuls provide convincing evidence ha gold can be used as a hedge and safe haven agains socks and bonds. 3
II. Lieraure eview Gold has many advanages over invesmen in socks and bonds or even foreign exchange rae. Gold is a angible good so ha when he invesor purchases gold yields an objec of angible value. Firs from he consumpion side he gold invesor no only purchases gold for hedging bu also he invesor benefis from using i as jewelry so ha he uiliy of gold is higher because i is considered consumpion good. Second from he producion side he producer can hold gold invenory o hedge himself form he sock ou risk. Third he gold is very liquid especially in ension imes so ha he invesor can pay higher prices and realizes lower reurns compared o oher risky asses However people fligh o less risky invesmens during bad saes of economy and consequenly he price of gold afer 2009 is subsanially increase. This fac agains he famous invesmen rule: buy low sell high. This sriking high prices lead o an expecaion ha i will coninue o rise forever bu according o he pas gold hisory his is no always he scenario.(davision 2013) My work is relaed o wo srands of lieraure. One sream focuses on examining he gold prices Fama and French (1988) sudy he relaion of meal pricing wih business cycles and hey find ha posiive demand chocks during peak periods lower he meal invenories and causes severe price conversions according o he heory of sorage while he oher srand invesigaes he relaionship beween gold prices and sock prices. Baur and Lucey (2010) invesigae wheher gold can serve as a safe haven and hedge agains sock and/or bonds during bad imes. The resuls show ha here is a fligh o qualiy from socks o gold during periods of ension bu no from bonds o gold. Baur and McDermo (2010) provide inernaional evidence o he role of gold as a hedge and a safe haven agains sock prices. In paricular hey run muli-counry analysis using daa from 53 inernaional sock markes (which include developed and 4
developing markes) from March 1997 o March 2009. Alernaively Capie Mills and Wood (2005) provide evidence on he role of gold as an exchange rae hedge and hey find ha here is a negaive relaion beween gold prices and Serling-Dollar and Yen-Dollar exchange raes. This paper is relaed o he fligh-o-qualiy lieraure. Gulko (2002) examines wheher he invesors ransfer heir invesmens from socks o bonds in he exreme marke condiions (Gonzalo and Olmo (2005)) saed ha invesors fligh o qualiy (from socks o bonds). from he above discussion i is clear ha here is one srand of lieraure ha finds ha Gold is a sock marke hedge while he oher sream provides evidence ha Gold is no hedge agains corporae bonds. Given he scarciy of lieraure on he role of gold as a hedging ool in he financial markes in general he conribuion of his sems from linking he above wo srands of lieraure by examining he relaion beween gold prices bond prices and sock prices over he enire sample period and during he bad saes of he economy wheher in recessionary and he financial crises sub periods. Barro and Misra (2013) find ha here is a saisically insignifican covariance of change in he gold s real rae wih consumpion and GDP growh rae and hey documen ha he prediced reurns on gold is very close o he risk free rae. Jaffe (1989) jusifies why ha he gold reurn is lower han socks and bonds by referring o is non-pecuniary benefis. The gold invesor no only purchase gold for hedging bu also he invesor benefis from using i as jewelry so ha he uiliy of gold is higher because i is considered consumpion good. Moreover from he producion side he producer can hold gold invenory o hedge himself form he sock ou risk. Finally he gold is very liquid especially in ension ime so ha he invesor can pay higher prices and realizes lower reurns compared o oher risky asses. McCown (2006) sudy he degree of he riskiness of gold by using CAPM model and Arbirage pricing model and find ha 5
he gold has a grea hedging abiliy because i has very similar expeced reurn of Treasury bill. They provide convincing evidence ha gold is zero bea asse and gold have no marke risk. However my paper ries o provide convincing evidence ha gold has negaive bea (i.e. comovemens agains marke porfolio) and o exend his o see he relaion beween gold marke sock marke porfolio and corporae bond marke afer aking ino accoun all Fama French hree risk facors. III. Mehodology 1. Hedging Hypohesis: My firs hypohesis herefore is ha gold may be used as a hedge insrumen agains socks and bonds if here is a zero or negaive relaion beween gold reurns and socks and bonds reurns during he enire sample period from 1986 o 2011. According o Baur and Lucey (2010) gold can be considered as a hedge agains bond and socks when here is a zero or negaive relaion beween gold and bonds and/or socks on average during periods of calm and ensions. 1.1.CAPM Since I am ineresed in he response of gold prices o flucuaions in sock reurns I run he following CAPM regression: (1) f 0 1 Sock f Where ) he daily reurn on gold prices is ) is he daily reurn on S&P index and ( f ( gold ( S& P ) is he risk-free rae. In order o examine he inerrelaions beween bonds sock and gold markes I incorporae he daily gold reurn ) o he above CAPM equaion as follows: ( bond (2) f 1 Sock f 2 bond f 6
Equaion (2) is he cenral because i examines he conemporaneous relaionship beween gold socks and bond in one equaion so ha as a robusness I used many measuremen for marke excess reurns. I used S&P500 Value weighed reurns wihou excluding dividends which is he same as marke excess reurn from Fama French Library VW value weighed reurns including dividends VWD equal weighed reurns EW and equal weighed reurns including dividends EWD. In empirical resul secion I will sar by displaying he resuls of his equaion and hen I will presen he resuls of CAPM and Fama French models. 1.2 Fama French Model: In order o accoun for he size and value premium I regress he reurn on gold on he hree Fama-French facors as follows: HML SMB (3) f 1 Sockj f 2 3 In addiion I also incorporae he bond reurns o equaion (3) as follows: gold f 3 1 Sock f 2 HML f SMB (4) f 1.2. Vecor Auoregression Model (VA) The VA sysem reas all of he variables in he model as endogenous variables. Therefore he dynamic relaion beween gold marke sock marke and bond marke can be examined by esimaing he following hree-vecor auoregressive (VA) sysem: I J 4 bond gold - f =l 0 + å a i gold-1 - f + å b j Sock- j - f + åh k bond-k - f + e i (5) i=1 j=1 k=1 K f I J K Sock f 0 i Sock 1 f j gold j f i 1 j 1 k 1 k bond k f i (6) 7
I J K bond f 0 i bond 1 f j gold j f i 1 j 1 k 1 k Sock k f i (7) 1.3. Impulse esponse Funcion (IF) The problem wih he variance-covariance esimaed from he VA model is ha errors are unlikely o be diagonal. This means ha i is difficul o shock one variable while holding oher variables consan. Therefore I use he impulse response funcion (IF) o measure he response of gold reurns o a lagged uni impulse in sock reurns while he bond reurns consan. Conversely I focus on examining he impac of he impulse bond reurns on gold reurns while holding he S&P index reurns consan. 2. Safe Haven Hypohesis: My second hypohesis is ha here should be fligh o qualiy from corporae bonds and sock marke o gold during exreme marke condiions. In oher words he safe haven hypohesis saes ha US invesors in he sock marke and bond marke view he gold as a hedge and safe haven o compensae hem for losses during sock marke crashes. Gold can be considered as a safe haven raher han hedge agains socks and bonds if here is a zero or negaive relaion beween gold reurns and bonds and socks during he ension imes only. In order o examine he safe haven hypohesis I esimae he following regression models: gold_ Tension f 0 1 (7) Sock _ Tension f gold_ Tension f gold_ Tension gold 0 f f 1 (8) 3 Sock _ Tension 8 f 2 bond_ Tension f 1 Sock _ Tension f 2 HML _ Tension 3 SMB _ Tension (9) 1 Sock 2 _ f HML Tension Tension SMB (10) _ Tension 4 bond_ Tension f
I will also used he VA and IF o es he second Hypohesis as follows: I J K gold _ Tension f 0 i gold _ Tension 1 f j Sock _ Tension j f i 1 j 1 k 1 I J K Sock _ Tension f 0 i Sock _ Tension 1 f j gold_ Tension j f i 1 j 1 k 1 I J K bond_ Tension f 0 i bond_ Tension 1 f j gold_ Tension j f i 1 j 1 k 1 k bond_ Tension k k k f bond_ Tension k Sock_ Tension k i f f (11) i i (12) (13) Where ) ) and ) are ineracion variables of reurns and ( gold _ Tension ( Sock _ Tension ( bond_ Tension dummy variable (Tension) ha akes value of 1 during he ension ime and zero oherwise. These ineracion variables represen daily reurn on gold Marke index and bonds during he crisis period respecively. IV. Daa and Variable Measuremen My sample period is exended from April 1 1986 ill Ocober 31 2012. The sample period will be divided furher ino differen subsamples o cover he periods of four exreme marke condiions (Ocober 1987 Crash Asian Crisis 1997-1998 Sepember eleven 2001 crash and he recen housing crisis 2007-2009). This sudy uses daily price daa from hree differen markes - gold sock and corporae bonds. The gold prices are he gold fixing price 3:0 P.M. (London ime) in London Bullion Marke based on U.S. dollars obained from London Bullion Marke Associaion hrough FED. Gold prices are expressed in U.S. dollars per roy ounce from April 3rd 1986 o December 31s 2012. I use he log daily reurns of he value-weighed (VW) and equal-weighed (EW) porfolios obained from CSP. The log ineres rae (TBL) is compued from he one-monh Treasury bill which is also obained from CSP. Addiionally I obain he daily daa of Corporae Aaa and Baa bonds yields in a percenage form from he Board of Governors of he Federal eserve Sysem which is originaed in Moody s invesor service ha includes bonds wih remaining mauriies as close as possible o 30 years 9
and drops he bonds if he remaining life falls beween 20 years if he bond is suscepible o redempion or if he raings change. Baur uses GACH o esimae he volailiy of socks included in his sample. This sudy also calculaes he condiional volailiy of gold and socks using GACH (1 1). I use he excess log daily reurns of gold socks and bonds. The marke excess reurns he Fama French hree risk facors and he reurns on he one monh Treasury bill are obained from Kenneh French websie. In order o es he safe haven hypohesis I need o focus on periods of bad saes of economy specifically speaking during sock marke crashes which are he Black Monday crash in 1987 Asian crises in 1997 he Sepember 11 2001 aack and he recen Housing crisis in 2007. Table (1) presens he saring dae for each marke crash or financial crisis. Table (1): Marke Crashes and Crisis Periods Crises Saring dae Marke crash (Black Monday) Ocober 17 h 1987 Sepember eleven Crash Sepember 11 2001 Asian Crisis July 2 nd 1997 Subprime crisis (Housing Bubble) July 1s 2007 1. Preliminary esuls: V. Empirical esuls Figure (1) shows he prices of gold from 1986 o 2012. Alhough he price of gold was no changed considerably from 1986 o 2002 i sars o increase dramaically afer he recen financial crisis. In addiion figure (2) show ha he gold volailiy and sock volailiy is very high during he seleced subsamples ha is why I concenraed on hese four criical periods o invesigae if he gold can be used as a safe haven agains socks and bonds or no. 10

Addiionally here is insignifican correlaion beween socks and bonds excess reurns and consequenly boh of hem can be included in he same equaion wihou he presence of he problem of mulicollineariy. 13
2. The Empirical esuls of esing he Hedging Hypohesis: 2.1. The Conemporaneous relaion beween gold socks and bonds. In his secion I examine he firs sudy hypoheses. I invesigae wheher gold can be used as a hedge agains socks and bonds or no. If I find significan negaive coefficien of he socks and bonds over he enire sample period his means ha invesors can depend on gold invesmen o hedge hemselves from he losses in he sock and bond markes. Table (4) repors he resuls of regressing he gold excess reurns on he sock reurns (S&P500 excess reurns mean excess value weighed reurns VW and he mean excess equal weighed reurns) and he corporae bond yields (Aaa and Baa) during he enire sample period (1986-2012). These resuls provide convincing evidence ha here is a negaive relaion beween he sock reurns and he gold prices reurns. In oher words if he value weighed reurns of all NYSE AMEX NASDAQ porfolio drops on average by 1% he gold reurns move o he opposie direcion by 0.02% and can be used as a hedge agains any surprising falls in he sock prices. This relaion is economically and saisically significan. The negaive relaion beween S&P500 and gold reurns are more dramaic and saisically significan because any drop in S&P500 reurns by 1% can be parially compensaed by increase in he gold reurns by 0.4% he saisics and he P-values show he probabiliies of acceping he null hypohesis. The negaive relaion beween corporae bonds yields and socks are more saisically bu less economically significan. We can imply from hese resuls ha gold can be used as a hedge agains drop in he sock reurns. This resul is Consisen wih Baur and Lucey (2006)) and Baur and McDermo (2009). Addiionally here is a saisically evidence ha gold can be used as hedge agains he drop in he corporae bond yields (Inconsisen wih Baur and Lucey (2006)). 14
My resuls can add o he exising lieraure by finding significan negaive relaion beween gold and bonds by using more comprehensive and curren daase for Aaa and Baa corporae bonds. Table (4) Hedging predicabiliy of gold over he period from 1986 o 2012 Table (4) repors he relaion beween gold reurns wih socks reurns and bonds yields. The dependen variables is he gold excess reurn f mean excess value-weighed and equal-weighed porfolios VW-TBL EW- TBL excluding dividends and he mean excess value weighed porfolios including dividends VWD-TBL EWD- TBL; and S&P 500 mean excess rerun are all proxy o he sock reurns. AAA-TBL and BAA-TBL yields are he bonds reurns. All raes are represened in annualized percenage poins.. The firs number in he hird column refers o he -saisic of he es and he second number refers o p value under he null hypohesis ha he gold canno be used as a hedge agains drop in he sock and bond reurns. 1986:04:01-2012:10:31 (6510 Obs.) f -saisic VW-TBL -0.0212** -1.93 (0.054) VWD-TBL -0.0212** -1.93 (0.054) EW-TBL 0.0041 0.31 (0.76) EWD-TBL 0.0040 0.30 (0.76) SP500-TBL -0.04*** -3.38 (0.00) AAA-TBL -0.00024*** BAA-TBL -0.00021*** The nex par use many models o es wheher his relaion is robus across many models especially afer conrolling for Fama-French hree facor model. 2.2.CAPM and Fama-French esuls: Table (5) repors he relaion beween he gold reurns and socks and bonds reurns. By using CAPM model o deermine if gold has zero bea or negaive bea wih he marke porfolio. Gold can be a srong hedge because is reurns commove agains he marke reurn. Afer adding he bonds o he CAPM model o deermine he relaion beween bonds reurns and gold reurns we find very significan negaive relaion beween bond reurns and gold reurns. Even afer conrolling for Fama French risk facors he negaive relaion beween marke excess reurns and gold remains robus. However i is obvious ha here is a posiive relaion 15-3.06 (0.00) -2.72 (0.00)
beween he beween small companies reurns and he large companies reurns. This implies ha small socks and gold may move wih he same direcion. However even afer conrolling for his posiive relaion he marke excess reurns as well as bonds excess reurns commove agains gold reurns.
