Biggest S&P 500 Movers on Tuesday 20 hr 32 min ago Advancers Spirit Aviation Holdings (FLYY) warned it may be unable to continue operations, citing an insufficient cash supply and difficulties in navigating operational challenges. Shares of the low-cost airline, which emerged from bankruptcy in March, plunged more than 40%, while shares of rival carriers rose. United Airlines (UAL) shares logged Tuesday’s top performance in the S&P 500, jumping 10.2%, while Delta Air Lines (DAL) shares gained 9.2%, as airline stocks also got a boost from inflation data that showed airfares rose last month. Paramount Skydance (PSKY) stock surged 8.4%. With Tuesday’s…

Here is an uncomfortable truth: most portfolio managers obsess over stock selection while treating portfolio construction as an afterthought. Warren Buffett once called diversification “protection against ignorance,” yet he and his successor hold over 30 stocks, each with a vastly different position size. The best investors know: success depends not just on what you own, but on how much. Yet portfolio construction remains the investment industry’s neglected stepchild. Managers spend countless hours researching stocks and timing the market. But when it comes to determining how much to allocate to each position? Too often, that decision is relegated to simple rules…
The FTSE 100 made steady progress on Wednesday, pushing back towards record highs, as hopes grew that the US Federal Reserve will lower interest rates in the coming months. Joshua Mahoney, analyst at Rostro, said markets are confident that the Fed will slash rates in the months to come. He added: “Market pricing for a rate cut at each of the remaining three meetings of 2025 have tipped above the 50% mark, meaning that it is now the base case scenario that we see rates at least 75bp lower by year-end. No wonder markets are in buoyant mood, with a…
Image source: Getty Images One thing I like about the FTSE 250 is that there is so much variety. With so many companies, industries, and market movers available, opportunities abound. Now, I don’t currently have exposure to Kier Group (LSE: KIE). The stock has been on a roll of late and it’s share price has been rocketing higher in 2025. I’m considering buying some shares in the FTSE 250 stock as I like the business, but there’s a reason why I don’t want to buy just yet. Strong trading update Kier is a UK-based construction and infrastructure services group. It’s…
On the beaches of Quintana Roo, the tide brings more than tourists. In 2025, record waves of sargassum threaten to choke the coastline’s turquoise brand—but engineers and scientists here are betting it can be turned into energy, products, and profit. A Forecast That Smells of Trouble For over a decade, brown rafts of sargassum have floated ashore from Cancún to Tulum, transforming clear water into murky shallows and driving visitors away. This year’s forecast is alarming. The University of South Florida’s Optical Oceanography Lab predicts up to 400,000 tons could land on Mexico’s shores, with daily arrivals in some parts…
Image source: Getty Images Thanks to a 15-fold rise in its share price, Rolls-Royce’s (LSE:RR.) market cap has exploded in recent years. Today, the company is worth a whopping £92bn, making it the sixth-largest company in the UK’s FTSE 100 index. It can get bigger though, according to CEO Tufan Erginbilgiç. He recently told the BBC that he believes Rolls-Royce could one day be the largest company on the London Stock Exchange (LSE). A nuclear energy powerhouse Erginbilgiç’s bullish view is largely based on Rolls-Royce’s operations in the nuclear energy industry. More specifically, it’s related to the company’s expertise in…
Image source: Getty Images Palantir Technologies (NASDAQ: PLTR) stock has produced truly eye-popping gains since ChatGPT was unleashed in late 2022. We’re talking about a near-2,500% return! That actually outdoes Nvidia, the kingpin of the whole AI revolution, whose shares are up by 1,000%. I don’t know how Nvidia shareholders could even put food on the table after such a measly return. A milestone quarter Palantir was the fourth most popular share on AJ Bell‘s platform over the past week, just ahead of Nvidia. The leading three were all juicy dividend payers, showing that this stock remains incredibly popular with…
Image source: Getty Images. Confidence among UK investors is souring rapidly as worries mount over the domestic economy. If this continues, the FTSE 250 index of shares — which is far more exposed to troubles at home than the internationally flavoured FTSE 100 — could be in for a tough time. According to Hargreaves Lansdown, confidence in the UK economy has slipped 16% among its clients this month. It says that “weak GDP growth, mixed messaging on fiscal plans, and wavering political clarity post-election have all added to investor caution“. Troublingly, it added that “confidence in the UK stock market…
By Johann M Cherian and Sanchayaita Roy (Reuters) – The benchmark S&P 500 and the Nasdaq hit record highs on Wednesday, underpinned by gains in megacap companies as investors were increasingly confident that the Federal Reserve could restart its monetary policy easing cycle next month. Signs that U.S. tariffs on imports have not fully filtered into headline consumer prices came as a relief for investors this week as they scour for insights on the impact trade uncertainty has had on the economy. Despite data showing underlying price pressures were on the rise, markets also factored in recent weakness in the…
Image source: Rolls-Royce plc Up 125%, the Rolls-Royce (LSE: RR.) share price has been one of the standouts on the FTSE 100 over the past year. It’s been driven by the firm’s impressive turnaround under CEO Tufan Erginbilgic that has been swift and decisive. It’s characterised by tighter cost controls, a focus on high-margin contracts and ambitious plans for the company’s Small Modular Reactor (SMR) nuclear programme. Subsequently, the company’s order book continues to expand, and investors appear convinced the recovery still has further to run. However, while the rally has rewarded shareholders handsomely, there are some ongoing developments that…
