The Week's Top Stories is a guided tour through the biggest market stories of the week, from winning stocks to brutal dips to the facts and forecasts generating buzz on Wall Street. 
It's the new Twitter! No, wait, it's a new competitor! Meta stock got lots of likes this week as it introduced a new platform called Threads, which is meant to take on the short-text social media OG. Like Twitter, Threads allows users to converse in real-time text conversations and makes it very easy for current Instagram users to sign up. Meta founder Mark Zuckerberg said 10 million users signed up in the first few hours and the platform has already been dubbed the "Twitter killer." Meta ended the week up about 2 percent.
There was good news for the job market, but bad news for investors Thursday when ADP announced private hiring was much stronger than expected in June. While workers are happy to be pulling in paychecks, strong hiring could lead to more rate hikes from the Federal Reserve as it struggles to get inflation under control. A milder-than-expected monthly report from the feds tempered the fallout Friday, helping the Dow Jones end the week down nearly 2 percent. At the last FOMC meeting, they opted not to raise them for the first time in over a year, but Fed Chair Jerome Powell noted that just because they passed on a rate hike this time, more increases are still very much on the table.
JetBlue rattled the markets Wednesday when it announced it will ditch an alliance with American Airlines in order to save its proposed takeover of Spirit. The Justice Department has been trying to block the Spirit acquisition and the American deal over fears about consolidation in the airline industry that would further stifle competition and drive up ticket prices. Both JetBlue and American stock dipped on the news Thursday but climbed back on Friday. It was good news for Spirit stockholders; shares rose on the news, ending the week up 8 percent. 
Your packages may not get where they need to go later this year and investors are watching. Labor negotiations broke down this week with both sides blaming the other for walking away from the table. The union says it wants a final offer, but the company says it delivered a "historic offer" that the union abandoned. If conditions continue to deteriorate, a strike could come at any time. The stock took a dive on Wednesday when this all came to a head, but will still end the week up about 2 percent.
