US President Donald Trump purchased shares in at least 20 companies just days before posting positive comments about them on social media, according to a review by CNN.

The findings highlight the intersection of political influence and market activity, as the president has repeatedly framed the recent surge in US equities as evidence of broad-based economic prosperity.

The investigation underscores the potential for market-moving commentary to follow personal investment decisions.

While the president has argued that "everybody is profiting" from the rally, the timing of these transactions suggests a direct link between his private portfolio and public endorsements.

This pattern adds complexity to the ongoing debate about the role of political figures in shaping market sentiment.

The review comes as markets continue to react to the administration's rhetoric on economic policy.
