Stock Market Today: A choppy stock day; a tweet on China; inflation cools; Nvidia, Tesla, Palantir originally appeared on TheStreet.

It's a bit of a choppy morning on Wall Street. Stocks opened lower after the president tweeted that China had "totally violated its agreement with us."

Breadth was weak, too, with 80% of S&P 500 stocks on the decline. At the same time, the index is well off the day's lows. As the heat map shows, it's a mixed day.

In the upper right corner is Costco  (COST) . The warehouse-club retailer's shares are higher following yesterday's earnings and revenue report, which beat expectations. Although the reaction was muted in after-hours trading, the shares are up 3% on strong volume.

This shouldn't be a surprise to members of TheStreet Pro. Our Bob Lang wrote Tuesday that Costco shares were primed to hit new highs following the earnings report.

Costco is also viewed positively within TheStreet Pro's Portfolio, and although we don't currently own it there, it's a stock we would like to buy on pullbacks.

Another stock that's up is the data-analytics-software provider Palantir  (PLTR) . That's a stock favored by TheStreet Pro's Stephen "Sarge" Guilfoyle. It's trading just below all-time highs.

The New York Times reports that "Trump Taps Palantir to Compile Data on Americans" as part of his March executive order requiring data sharing across government agencies.

At the same time, Sarge reports that he's taken some profits in Palantir and other tech names. He still likes the stock, but is a trader at heart.

You won't go broke taking a profit!

The weekend is almost here! We're expected to have a lovely one in Colorado. I hope yours will be similarly wonderful.

I wasn't planning to start the day with a tweet, but let's do it.

This has prompted what was a fairly flat market to drop today. As I write this, S&P futures are down 33 points. The Nasdaq is lower by 130, and crude oil is now down 52 cents after being about 70 cents higher.
