Intel early Friday was on track to notch its best weeklong stretch in nearly 40 years before the rally sputtered.

The Trump administration has effectively put a buy rating on Intel’s stock. But that alone won’t get the troubled chip maker out of its jam. Intel’s shares have soared 22% so far this week. The run started after Vice President JD Vance delivered a speech at an AI summit in Paris early Tuesday that touted the White House’s aim to shore up domestic chip production.

Investors are betting that Intel and TSMC will form some kind of joint venture. The Trump administration wants the U.S. to be a leader in advanced chip manufacturing. Intel has struggled thus far in its plans to open its foundry business to outside customers.
