Election day has finally arrived in the USA and the results are still on a knife edge. The results of the Trump-Harris Presidential runoff could have significant short- and long-term ramifications, including for UK shares and shares around the world.

Here are two FTSE100 Stocks that could increase in value if Donald Trump returns to the White House.

BAE Systems

defense enterprises BAE Systems (LSE:BA.) has increased in value since Russia’s invasion of Ukraine in 2022. After the end of the Cold War, demand for weapons increased as Western countries restocked their arsenals. This is a trend that is likely to continue as geopolitical tensions increase.

If Trump is successful today, defense industry sales could get an extra shot in the arm. Military improvement is one of his stated priorities, including building the ‘Iron Dome’ missile defense system and implementing large-scale modernization.

This could create a windfall for BAE Systems given its status as a top supplier in the US. Last year, the company generated 42% of its revenue from there, making it the company’s largest market.

But that’s not all. Trump’s presidency could also have significant impacts on other countries’ defense spending.

Criticizing NATO countries for failing to meet their spending obligations was a hallmark of his last term as President. And if he wins, there are rumors that he will demand that the defense bloc increase arms-related spending to 3% of gross domestic product (GDP), from the current 2%.

Defense companies like BAE still face threats such as supply chain issues and cost inflation. But from all angles, I think the FTSE company looks to be in very good shape.

Shell

If his latest stint in the White House is any guide, the oil industry could also be a major beneficiary of Trump’s election victory. Invest Shell (LSE:SHELL) could be a good game on this theme.

The former President implemented a wide range of measures supporting fossil fuel producers between 2016 and 2020. He increased the number of drilling leases on federal lands, approved pipeline projects like Keystone XL, and pushed back on environmental legislation to help businesses cut costs.

Trump’s support for the oil industry has not diminished in the intervening years. On the campaign trail, he promised to increase production as part of his ‘America First’ policy.

If Trump wins today, Shell could be one of the big winners. It is one of the world’s largest oil and gas producers, operating in 70 countries. It generates significant revenues from the United States thanks to its extensive refining operations and upstream assets.

However, no matter who secures the election, there will still be risks in investing in oil companies. The oil market is facing a massive oversupply as China’s economy cools and new capacity comes online. This could negatively impact producers by ensuring oil prices remain on their recent downward path. they come.

Moreover, countries are investing heavily in renewable energy to get rid of oil and gas, which poses a long-term problem. But Shell’s own investment in renewables could help limit this danger.
