NEW YORK (TheStreet) -- The Trump Rally brought the DOW up about 5% for the week and it's expected to continue to rise, despite a slowdown today, TJM Investments managing director Tim Anderson said on CNBC's "Closing Bell" on Friday afternoon.

The rally started on Wednesday, the day after Republican candidate Donald Trump won the presidential election, as investors adjusted their portfolios to benefit from his promised efforts to decrease regulation in the healthcare and banking sectors, as well as to spend $1 trillion on new infrastructure. 

"Do you want to be a part of this rally? Does it continue or are you fading it?" CNBC's Bill Griffeth asked Anderson. 

"I just think it's got to continue because I think that the biggest institutional money managers have been operating under one game plan for the last eight years," Anderson said. "And now, in an unexpected election outcome, they're looking at a much different investment landscape for minimally the next four years." 

Those managers are going to need more than a few weeks to set up investments how they want them to be under a Trump administration, he noted. "They're probably shifting from bonds to stocks, and they're probably going to make massive asset allocation shifts within sectors within the equity part of the universe." 

"They're already doing that as you can see with the infrastructure play and healthcare," Griffeth said. 

"There's no doubt about it," Anderson said. That's one reason that the S&P 500 is "lagging a little bit" today after advancing earlier this week on the Trump rally. "There's significant winners and losers. You can already see it's more than just short covering and a few traders punting around."
