Stock market prices have skyrocketed since the start of the year, but a recent plunge in technology stocks could have a knock-on effect for American Airlines and its app platform.

The technology stocks have seen strong gains as the Trump administration has slashed government support for innovation and reduced funding for research.

The latest tech stocks have risen more than 40 percent since December.

The Nasdaq Composite Index of companies that make electronic devices, including cell phones, tablets and computers, surged more than 4 percent in December after hitting a record high earlier in the year.

American Airlines stock has jumped more than 50 percent since its high in February.

The Nascent Composite, which includes airlines, technology and telecom companies, jumped 9.3 percent last month.

“The Nasco has gone crazy.

The Nasco is a joke,” said David J. Fenton, an investment strategist at T. Rowe Price.

American Airlines stock is up more than 80 percent since the beginning of the Trump era, while its apps have risen nearly 20 percent.

The company’s stock is the third-largest in the United States after Google and Facebook.

Nasdaq shares, which have been trading near record highs since the election, have been outperforming the S&P 500 by nearly 20 basis points in 2017.

The S&P 500 has been above the 50-day moving average for the past seven years.

The Dow Jones Industrial Average, which tracks the Dow Jones industrial average, rose more than 500 points on Tuesday.
