Global shares extend gains

US stocks scored their biggest gains in a month on Tuesday after Coca-Cola led a round of strong earnings and as concerns about Europe's debt crisis eased as Spanish bond yields fell.

The Dow Jones industrial average rose 194.13 points, or 1.50 percent, to close at 13,115.54. The S&P 500 Index gained 21.21 points, or 1.55 percent, to 1,390.78. The Nasdaq Composite climbed 54.42 points, or 1.82 percent, to 3,042.82.

In Tuesday's rally, each of the three major indexes booked their largest percentage gains since March 13.

European shares rallied, with banks leading gains, after a well-received Spanish debt auction, an upbeat German economic sentiment reading and positive US corporate earnings releases boosted investor sentiment.

The FTSEurofirst 300 index closed up 2.0 percent at 1,053.12 points, near the session peak and back at levels seen before the Easter break.

In Tokyo, Japanese shares steadied today after the previous session's sharp losses, though social gaming firm Gree Inc jumped as an upbeat sector report from Bank of America Merrill Lynch forced investors to cover short positions.

The Nikkei closed down 0.1 percent at 9,464.71 after shedding 1.7 percent on Monday, falling below the psychological key level of 9,500 on concerns over Spain's ability to finance its debt. The broader Topix was down 0.1 percent at 803.09.
