Inkcazo yeVanna kunye nendlela yokuSebenzisa ngayo
Ngokukodwa, iVanna yinqanaba apho i- delta (Δ) yolukhetho luya kutshintsha ngokubhekiselele ekutshintsheni kwintando yokungena kwayo. I-Vanna nayo isantya apho i-vega (v) yekhontrakthi yokukhetha iyakushintsha ngokumalunga notshintsho kwixabiso lentengiso yalo.
Yilungelelaniso lwesibini kunye kwaye luncedo xa umrhwebi wenza i-delta- okanye ye-vega-hedged trade.
Njengemvelaphi emfutshane, i-delta inyathelo elingaphi indlela okukhethwa ngayo inxulumene nexabiso lexabiso le-asethi. IVega yenza amanyathelo okutshintsha kwezinto ezinokuthi utshintsho kwi-asethi ephantsi lukhethwa.
Ukubala kweVanna
I-Vanna yinto yesibini ephuma kwixabiso lezinto ezikhethiweyo okanye isivumelwano semvume ngokubhekiselele kwintengo kunye nokungahambisani nentengiso. Umsebenzi wokuqala kaVanna ukuvavanya ubudlelwane phakathi kweGrike yokuqala ye-delta ne-vega. Ngamanye amagama, lijongene nolwalamano oludibeneyo lweenguqu kwiintlobo zombini kunye nentengo yexabiso le-asethi.
Ukusebenzisa iVanna kwiShishini
I-Vanna iyinqanaba apho i-delta ne-vega yezinto ezikhethiweyo okanye i-contract mandatory ziya kuguqulwa njengokuba ukungabi nantoni kunye nexabiso lentengo yokutshintsha kweemarike ngokulandelanayo. Abahwebi abafuna ukwenza ukhetho okanye ukugunyaza urhwebo apho i-delta okanye i-vega ingatshintshanga nantoni na eyenzekayo kwimarike engaphantsi iya kufuna ukusebenzisa iVanna.
Njengomlinganiselo wesondlo-wesibini-usebenzisa izikhetho zokuqala ezifana neDelta kunye ne-vega ekubaleni-kunokubanzima kwaye kunzima ukuzama ukucinga ngazo zonke iindlela i-Delta ne-vega ezinokuchaphazela ngayo i-Vanna, okanye indlela iVanna eya kuchaphazela ngayo delta kunye / okanye vega. Nazi izimbalwa ezimbalwa oza kuziqwalasela:
- Izinketho zefowuni zineVanna enhle, kwaye ke yenza izikhundla ezimfutshane. Faka iindlela zokukhetha iVanna engathandekiyo, njengokuba ukhetha izikhundla ezifutshane. Oku kungenxa yokunyuka kwezinto ezinokuzithengisa-i-vega inyathelo le mpembelelo-iya kwandisa utshintsho lwenketho ehambayo kwimali .
- Ngokusekelwe kwezi zikhokelo ezingentla ngasentla, ukujonga iVanna kunokukunika indlela yokukhawuleza ukuba uhlole ukuba iipotfoliyo zakho zikhethiweyo ezide / ezifutshane mfowuni / ubeka xa unamathuba amaninzi.
Igama lokugqibela kwiVanna
Njengomyalelo wesibini wesiGrike, iVanna ngokuqhelekileyo iza kuba luncedo kubahwebi abandakanyekayo kwiinkqubo ezinobunzima bokuthengisa okanye kubahwebi abambe iphothifoliyo yokukhetha. Abathengi abathengisa okanye bathengisa enye okanye ezimbini iindlela zokukhetha ngexesha, ukucinga ngokunyuka okanye ukuwa okanye ukungabikho kokunyuka kwe-asethi esezantsi, ngokuqhelekileyo akuyi kudingeke ukuba kuqwalaselwe ukubalwa kwe-Vanna. Umsebenzi oyintloko kaVanna kukujonga ubuhlobo obudibeneyo neenguqu kwiintlobo zombini kunye nentengo yexabiso le-asethi.
