Share price probably

Companies close to trump are likely to get preferential treatment

Investors typically try to invest in companies they expect to grow in value. Many of them (particularly institutional investors) do not care what the company they're investing in does, they just care that the line goes up after they buy and before they sell.

Investors buying shares all at once push the asset price up

My theory, these kinds of companies put their logo next to trump in the hope it triggers a spike in investment and therefore a boost to their share value.

That in addition to the old classic, if they get something like an ad spot for their bribe, it becomes just a business transaction.
