A flurry of mergers and acquisitions, along with earnings reports, pushed the markets into the green on Monday, with T-Mobile (TMUS) - Get Report  hitting new highs and B/E Aerospace (BEAV)  soaring on deal news. 

The S&P 500 closed up 0.47%, the Dow Jones Industrial Average was climbed 0.43%, and the Nasdaq popped 1%.

T-Mobile led the Nasdaq, closing up 9.5%. The mobile communications company reported adjusted earnings of 27 cents a share, beating estimates of 21 cents a share, based on the FactSet consensus estimate. T-Mobile said total revenue increased 17.8% to $9.2 billion, and it added 2 million customers during the quarter. T-Mobile's shares are up more than 30% this year.

Rockwell Collins (COL) announced a deal valued at $8.3 billion, including debt, to acquire B/E Aerospace (BEAV) . Rockwell Collins is trying to increase its exposure to the commercial aircraft cabin. On the deal news, Rockwell Collins stock fell 6.2%, pulling the S&P 500 slightly lower though still in positive territory. B/E Aerospace shares jumped 16.4%.

"That's a great merger because Boeing and Bombardier and Airbus have been squeezing their suppliers endlessly," said TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio. "Rockwell gets together with BEA -- maybe that has has a little more heft, a little more staying power and a little more bargaining power. That's makes a lot of sense to me."

AT&T (T) - Get Report agreed to buy Time Warner (TWX) in an $85.4 billion deal, paying $107.50 a share. If approved by regulators, the deal will create a behemoth media and telecommunications company that combines internet services and programming.

"When you're talking about doing really tight integration, ownership is always best," AT&T CEO Randall Stephenson said on an earnings call Monday. "If you have to innovate quickly, it's really difficult to do in a partnering, arms-length negotiated-type transaction. When it's completely owned, you just move a lot faster."

The deal values Time Warner at a 20% premium to its $89.48 closing price on Friday. Time Warner shareholders would receive $53.75 a share in cash and $53.75 a share in AT&T stock. The total transaction value is $108.7 billion, after including Time Warner's net debt, the companies said.

AT&T reported that consolidated revenues for the quarter were $40.9 billion, up 4.6%. The company increased its quarterly dividend to 48 cents a share, or a 5.2% yield at the current valuation.

TheStreet's Jim Cramer, said investors shouldn't buy either stock because AT&T's bid for Time Warner is an "expensive way for the telecom company to stay relevant," while requiring it to compete with companies like Google (GOOGL) - Get Report and Facebook (FB) - Get Report . AT&T will also have to battle for regulatory approval amid negative rhetoric from politicians, Cramer highlighted.

"The regulators are in no mood for this deal," Cramer wrote in a note. "AT&T thought about buying T-Mobile in March of 2011 and got it wrong that time because of worries about competition lessening. I think AT&T will get it wrong this time because of worries of too much concentration -- nothing they teach you in antitrust law, but everything the populist political environment says."

Time Warner shares closed down 3% in trading on Monday, while AT&T shares were 1.7% lower.

In other deal news, TD Ameritrade (AMTD) - Get Report said Monday that it entered into a "definitive agreement" to purchase online brokerage Scottrade Financial Services in a cash-and-stock deal valued at $4 billion.

TD Ameritrade, the biggest discount brokerage by trade executions, said it expected to realize about $450 million in combined annual expense synergies, and more than $300 million in additional longer-term opportunities once the deal closes. TD Ameritrade's shares were down 4.4%.

"That's the kind of acquisition that I like because it takes out a competitor and therefore makes them more powerful," TheStreet's Cramer said, speaking from the floor of the New York Stock Exchange Monday about the TD Ameritrade deal. "I applaud that merger."

"The latest reading signaled a solid upturn in overall business conditions, and the rate of improvement was the fastest since October 2015," IHS Markit wrote in its report.

The Federal Reserve Open Market Committee enters a blackout period prior to its meeting on Nov. 1 and 2; before that, four Fed speakers are expected to speak Monday.

New York Fed Bank President William Dudley spoke at 9 a.m. on the U.S. Treasury market, while St. Louis Fed President James Bullard spoke at 9:05 a.m. to the Association for University Business and Economic Research in Fayetteville, Ark.

Bullard said over the next two or three years, as the U.S. struggles with slow productivity, low interest rates will likely persist.

"Real safe rates of return are exceptionally low at present and are not expected to rise soon," Bullard said. "This means, in turn, that the policy rate should be expected to remain exceptionally low over the forecast horizon," he said.

In the afternoon, Chicago Fed President Charles Evans discussed monetary policy, and Fed Board Governor Jerome Powell spoke on the future of Treasury market settlement transactions. Powell said that Bank of New York Mellon (BK) - Get Report will dominate the U.S. government securities settlement structure as JPMorgan Chase (JPM) - Get Report plans to exit. Evans highlighted the reasons for lower potential output growth: slower growth in labor force, plateauing labor quality, weak capital investment, and slower pace of technological improvement, while saying that inflation targets should match timing of interest rate increases.
