Dominating the tech-heavy S&P 500 (^GSPC) this year were the Magnificent Seven tech stocks — Amazon (AMZN), Apple (AAPL), Alphabet (GOOG, GOOGL), Nvidia (NVDA), Meta (META), Microsoft (MSFT), and Tesla (TSLA) — which are up around 70% year-to-date. Many of these companies have, in some form or another, implemented the buzziest tech of Wall Street: Artificial intelligence. With such a strong performance, it begs the question of whether these companies and AI have hit their peaks or will they continue to grow in 2024? TECHnalysis Research, LLC President and Chief Analyst Bob O'Donnell joins Yahoo Finance to discuss AI and its use within these companies as we head into 2024. "You think about things like Microsoft's 365, Google's Workspace. Now, what's happening is really it's been a tech industry discussion and a little bit of a financial industry discussion, but those tools are starting to get into the hands of people, and really, we won't see that until 2024," O'Donnell says. "And I think a lot of people are just going to have their minds blown by this stuff, because it really is powerful stuff."

As economic data continues to filter in this week, including the Consumer Price Index (CPI) and Producer Price Index (PPI), the Federal Reserve's interest rate decision out on Wednesday, December 13 is "the real highlight," as Yahoo Finance's Josh Schafer notes. Core CPI for the month of November increased 4.0 percent year-over-year and 0.3 percent month-over-month, coming in-line with estimates. Yahoo Finance spoke to industry analysts and experts to discuss what investors need to know from the Fed’s upcoming interest rate decision and what recent data means for the economy. "Inflation has been falling quicker than people expect," Yahoo Finance's Josh Schafer explains, as he takes a look at Goldman Sachs Global Investment Research inflation forecasts, which show inflation continuing to drop over the next year. Federal Reserve Chair Jerome Powell is "not likely to signal that the Fed is confident enough to be done right now or to take the potential of rate hikes off the table," Yahoo Finance Fed Reporter Jennifer Schonberger says, citing two reasons. "One reason, he doesn't want financial conditions to loosen and number two, he wants to talk down market expectations for aggressive rate cuts next year." eToro U.S. Investment Analyst Callie Cox discusses why she "wouldn't be surprised to see Powell push back a little bit on this notion of rate cuts... I think that he’ll hint to more flexibility, without promising rate cuts." Cox notes the phrase that she's "paying attention to" from Powell is "the balance of risks in the economy." "He is referring to the dual mandate of... promoting healthy... employment while... controlling inflation." Azoria Partners CEO and CIO James Fishback explains why he thinks "tomorrow's meeting is going to be a big one." "Coming into this meeting, the Fed was saying we’re going to only cut once next year… and look at what the market's pricing, they're going to cut four times. So that has to resolve itself. I don't see Powell actually validating any of that dovishness that the market is currently professing." "Relative to what market consensus is at the moment… it will be a hawkish meeting tomorrow," Fishback says. State Street Senior Global Macro Strategist Marvin Loh notes that "if we are higher for longer, to me, that means that there's more problems that can arise, either in the banking system or in the fact that there are a lot of consumers that are already tapped." "It's going to take longer before the Fed gets comfortable that that consumer strength is coming down. So in a lot of ways we're going to see... this potential soft landing narrative continue until it doesn't."

An analysis from the Washington Post showed that 8 fatal accidents that occurred with Tesla's (TSLA) autopilot features in its vehicles took place where they should not have been accessible, according to Tesla manuals. With recent questionable actions and comments from CEO Elon Musk, could this affect the company's outlook for 2024 and broader adoption of EVs? Colin Rusch, Oppenheimer Managing Director & Senior Research Analyst, joins Yahoo Finance to discuss the analysis and what it means for Tesla heading into next year. Rusch said,"As we move forward with this technology, I think it's part of a larger branding issue for Tesla, in terms of how they present themselves because they were seen as the leading company on bringing clean, safe vehicles to market, and now as the reality comes forward, there is a lot more going on here."

A drug that literally makes people lose weight. A decade ago, that would have been considered a gimmick if not an outright hoax. Today, it is a reality that has not only changed the weight-loss game for good, but holds the potential to disrupt numerous sectors related to peoples’ physical shape and size — clothing manufacturers and food producers being but two examples. It’s not often that a drug comes along that changes the course of history. Yet that’s exactly what Novo Nordisk’s Ozempic and its sister drug Wegovy have done - and why Novo Nordisk (NVO), in its 100th year of operation, is Yahoo Finance’s 2023 Company of the Year. Recent research from Goldman Sachs projects 15 million adults in the US will be on anti-obesity medications by 2030, representing 13% penetration in the US adult population — not including diabetic patients. That’s already translated into some weighty sales numbers for Novo, in turn sending its stock price up close to 50% through 2023, well ahead of the S&P 500’s 20% gain. To be sure, Ozempic is not necessarily the foolproof magic weight-loss elixir that some analysts and investors think and expect it to be. On the contrary, there is competition, knock-offs, and much more research and development ahead to truly make diabetes and by extension obesity a thing of the past.
