European equities are getting some investor interest again.

As the ongoing debt crisis erodes consumer spending and corporate profits, the euro zone’s share  in investors’ equity portfolios has fallen in the past year –Reuters polls show holdings of euro zone stocks at 25 percent versus over 36 percent a year back.  Cash has fled instead to U.S. stocks, opening up a record valuation gap between the European and U.S. shares. (see graphics below from my colleague Scott Barber). In fact no other region has ever been considered as cheap as the euro zone is now,  a monthly survey by Bank of America/Merrill Lynch found in June.

That could offer investors a powerful incentive to return, especially as there are signs of serious efforts to tackle the crisis by deploying the euro zone’s rescue fund.

Pioneer Investments has moved to an overweight position on European stocks. While Pioneer’s head of global asset allocation research Monica Defend stresses the overweight is a small one compared to, say, its position in emerging markets, she says:
