Ciao, why the Dow and the SP500 went so up last week? I mean did not investors have fear about the Greek elections? How they could be sure Syriza would have lose, if the situation was not sure in the polls? Especially with the influence of the scandal of Goldmansachs! There is a method to see if the indexes went up more because of the buy actions of big institutional investors, or if there were little speculations of isolated people( a good KPI could be to see the amount of stock bought for single investor)? As newbe, psychologically it was not more wise to wait Sunday considering the high degree of incertitude and the crucial event represented by these elections?
