Certain stocks and sectors could see a boost now that the special counsel investigation is over, allowing an unfettered President Donald Trump to turn his focus back to policymaking, both against and, in some cases, with the Democrats, analysts said. Robert Mueller's 22-month-long probe found no evidence of Trump collusion with Russia in the 2016 presidential campaign, lifting the cloud that had been hanging over his presidency since his inauguration.

Infrastructure

One of Trump's long-held goals that has been pushed aside is his trillion-dollar infrastructure plan. Although the plan is somewhat supported on both sides of the political aisle, the parties diverge on how to fund the pricey investment. However, infrastructure is still on Trump's mind. The president said just last week that he and House Speaker Nancy Pelosi are still talking about an elusive infrastructure deal. Strategas has an infrastructure basket consisting of about 20 companies in traditional highway infrastructure that could benefit from any deal. The portfolio was created in 2008 to play President Barack Obama's stimulus in 2009, and the constituents have gained with the passage of highway bills over the years, according to Strategas. The member stocks include pipeline services company Aegion Corp., general contractor Granite Construction, engineering company KBR and building material company Simpson Manufacturing. However, a large bipartisan infrastructure bill is unlikely if Trump uses the Mueller outcome against the Democrats, and they in turn keep their intense investigations of the president. "Is it time for infrastructure? Democrats and the administration are very far apart," James Pethokoukis, economic analyst at the American Enterprise Institute, said on CNBC's "Squawk Box" on Monday. "I highly doubt we are going to see anything like that. Maybe if this was like the beginning of last year, now that we are deep into the election season, I don't think so."

Health care

The new development is positive for health insurers as a Democratic sweep in the Senate is now less likely in 2020, alleviating the risks of having big changes to the health-care system, according to one industry analyst. A divided government post 2020 "reduces market perception of single payer risks," Lance Wilkes, equity analyst at at Bernstein, said in a note. "We see continued pressure on drug prices and middlemen, ongoing Medicaid expansion at a state level, and the potential for stabilization of public exchange funding and policies." Bernstein noted insurers and government Managed Care Organizations took a hit since the introduction of the "Medicare-for-all" bill in the House as Anthem, UnitedHealth, Centene and Humana were down as much as 11 percent. "We would see this environment as positive for government Managed Care Organizations, Anthem and its company specific earnings drivers, and continued policy pressure on Pharmacy benefit managements," Wilkes said.
