The three corporate leaders all issued statements that either cited the violence in Charlottesville, a disaffection with American politics, or a condemnation of hatred as reasons for their departure from the advisory group.

Intel CEO Brian Krzanich, Merck CEO Kenneth Frazier and Under Armour CEO Kevin Plank have all resigned from the American Manufacturing Council since deadly violence erupted during clashes between protesters over the weekend in Charlottesville, Virginia.

Companies led by the three CEOs who left a presidential advisory council this week all have share prices that have badly underperformed their peers this year, CNBC research shows.

Yet their decisions also call attention to their respective company stock prices, and all have had a rough time during the Trump administration.

Intel shares, for example, are down about 1 percent for the year, while the Dow Jones industrial average of which is a component, was up more than 11 percent as of Tuesday morning.

Wall Street analysts who rate Intel's stock expect the chipmaker to post a 3 percent rise in sales this year, while earnings per share are seen climbing to $3.01, up from $2.72 in 2016, according to Thomson Reuters data.

Intel shares were down 1.3 percent midafternoon Tuesday.

Merck, also a Dow component, has seen its shares rise 6.6 percent this year, or less than half the gain in the Dow.

Its sales are expected to tick up 1.2 percent this year, while profit is seen rising to $3.87 a share, versus $3.78 last year, based on analysts' consensus earning forecast.

Merck shares were slightly higher Tuesday afternoon.

Under Armour has fared even worse this year, plunging more than 34 percent year to date, versus a 10 percent rise in the index.

The company's share-price drop began shortly after President Donald Trump took office in late January, thanks to a fourth-quarter earnings report and a forecast .

Under Armour shares were down 4.1 percent in midafternoon Tuesday.
