If you think Hillary Clinton's headed to the White House, here's how you can bet on it through the stock market.

If you think Hillary Clinton's headed to the White House, maybe you should bet on it. That's not really possible in the United States, of course, but you can always buy stocks instead.
We've put together a portfolio of 15 stocks experts think should do well under a Clinton presidency. So, the more it looks like she might be elected, the more lift these stocks should get. The markets have already responded to her comments on the campaign trail on more than one occasion.
Each week until the election, we'll be checking back in with the portfolio, measuring the performance of each of these investments, which, in turn, could also give us some indication of Clinton's chances. We've included a chart measuring the stock's performance since Clinton announced her candidacy on April 12, 2015. We'll continue to update the charts and our analysis of the portfolio as the campaign progresses.

HCA Holdings (HCA)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: +2.70%
HCA Holdings is a for-profit health care services company that operates hospitals and other related facilities.

Aetna (AET)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: +11.63%
The company would benefit from a Clinton presidency on two fronts: in the Obamacare exchanges (which under her would likely be fixed), and in Medicare Advantage (a substitute for parts of original Medicare that is likely to expand). Especially if its planned acquisition of Humana (HUM) goes through.

SolarCity (SCTY)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: -52.84%

Renewable Energy Group (REGI)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: -4.61%
Renewable Energy Group produces biofuels and develops renewable chemicals.

Aecom (ACM)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: +6.56%
Aecom provides professional engineering, consulting and project management services for infrastructure projects.

Goldman Sachs (GS)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: -18.01%
Goldman Sachs has been a sore spot for Clinton the campaign trail, with her foes on both the left and the right critiquing paid speeches she gave at the firm. Even though the former first lady has said she would get tough on Wall Street in the White House, it is unlikely she would really go after Goldman and others all that hard. Moreover, the degree of certainty Clinton represents compared to her opponent, Donald Trump, might help bankers wary of market volatility sleep at night.

Walmart (WMT)
Performance since Clinton announced on April 12, 2015 through July 25, 2016, the start of the Democratic National Convention: -8.87%
Clinton has said that as president she will support raising the federal minimum wage to $12 and that where it can be raised to $15, it should be. While such a maneuver would mean many companies would have to increase wages, it would also put more money into consumers' pockets. According to an analysis from S&P Capital IQ, large retailers like Walmart and competitor Target are well-positioned to absorb wage hikes and would benefit from lower-income consumers having more to spend in their stores.
