Investors should not fear a stockmarket crash

Shareholders are enjoying one of their best runs in history. Since a trough last October the S&P 500 index of large American firms has risen by more than 40%; peers in Europe, Japan and Canada have all gone up by at least half as much. The fears of last year, that stubborn inflation would prevent central banks from cutting interest rates, keeping bond yields high and dragging share prices down, have all but vanished. In fact, many of the world’s monetary guardians have been slashing borrowing costs just as corporate profits have climbed and animal spirits have surged. The result is that plenty of stockmarkets are now hovering near all-time highs.
