TORONTO — The Toronto stock market racked up a solid gain Tuesday amid merger and acquisition activity and data pointing to strong German investor optimism which eased fears that Europe’s biggest economy could be headed into recession.

Its shares were earlier halted on the TSX but later gained 65 cents to $27.43.And there were reports that retailers Office Depot and OfficeMax are discussing a merger.The Wall Street Journal said that OfficeMax and Office Depot were considering a deal to combine, which would result in big cost savings. The paper said an announcement could come as early as this week.U.S. stocks also  rose as this year’s ongoing surge in merger activity suggested investors were still finding value in the market even as indexes closed in on all-time highs.The Dow Jones industrial average rose 53.91 points to 14,035.67, the Nasdaq composite index was up 21.56 points at 3,213.59 and the S&P 500 index climbed 11.15 points to 1,530.94.The German data came as a relief after another economic report last week showed the country’s economy shrank 0.6 per cent in the fourth quarter. A drop in the first quarter of this year would put it in a technical recession but many economists think the dip was only temporary and that the economy will quickly return to growth.“The slide in German activity has been concerning in recent months so to get the data we got today suggests that there might be some stabilization going on in some of the more bellwether economies there as well,” said Craig Fehr, Canadian markets specialist at Edward Jones in St. Louis.However, the optimism was tempered somewhat by worries about the looming sequester in the U.S. That is a huge package of across the board spending cuts worth US$85 billion that are set to take effect at the end of the month unless lawmakers can agree on other cuts that would be more selective.It would cut a big chunk out of American economic growth, a worrisome prospect for a struggling economy.“If it goes into place, which I think is a reasonable potential, you’re looking at about eight-tenths of a per cent drag on the economy this year,” added Fehr.“That’s meaningful when you’re talking about an economy only growing at two per cent (but) the important thing is we’re not talking about a tipping point back into recession.”Last Thursday, JPMorgan Chase cut its forecast for U.S. growth in 2013 to 1.9 per cent from 2.1 per cent, citing the rising odds that the spending reductions will actually take place.Telecoms led TSX gainers, up 1.58 per cent with Rogers Communications (TSX:RCI.B) continuing to benefit from a strong earnings report Friday, up $1.17 at $48.49.The financial sector ran ahead 1.2 per cent as Royal Bank (TSX:RY) advanced $1.13 to $64.43.The information technology sector was ahead 1.03 per cent as BlackBerry (TSX:BB) gained 34 cents to $14.57 even as Canaccord Genuity slashed its estimate of BlackBerry BB10 smartphone shipments in February to just 300,000 units, a far cry from its earlier estimate of more than 1.75 million.The equities research unit of Canaccord Financial Inc.
