Best Buy's share price recently did something that surprised a lot of investors who had written off the electronics retailer. After reporting its latest earnings, the stock moved by roughly how much in a single day?
a. Best Buy's stock jumped 15% after reporting better-than-expected earnings. The result defied the prevailing narrative that big-box electronics retailers are in terminal decline, showing that cost discipline and selective promotions can still produce upside surprises. For context, a 15% single-day move is enormous for an established retailer — it reflects just how bearish the market had become before the report landed.
The drinks industry is seeing a generational shift this year. Hard seltzers — fizzy alcoholic water drinks like White Claw — dominated the last decade, but a new category is now stealing the spotlight among Gen Z drinkers. What is replacing them?
b. Non-carbonated alcoholic drinks such as Surfside iced teas and BeatBox party punches are displacing hard seltzers as the trendy choice among Gen Z drinkers. The shift matters commercially because it signals that the seltzer boom — which reshaped the entire beer-and-spirits supply chain — may have peaked. Brands that bet heavily on fizzy formats are now scrambling to reformulate, while newer entrants built around still drinks are capturing shelf space and marketing budgets.
American Airlines just announced a major overhaul of in-flight Wi-Fi across more than 500 of its aircraft. The airline is ditching its existing provider and switching to a satellite internet service that many passengers will recognise from another context. Which service is it installing?
c. American Airlines is equipping more than 500 planes with SpaceX's Starlink satellite internet. Starlink uses a large constellation of low-Earth-orbit satellites to deliver faster, lower-latency broadband than older in-flight systems — a meaningful upgrade for passengers used to painfully slow plane Wi-Fi. The deal is a commercial coup for Elon Musk's space venture, which is increasingly competing in enterprise and infrastructure markets well beyond its original consumer broadband focus.
A fraudster recently claimed he was about to acquire Honey Birdette, a high-end lingerie brand. He raised real money from investors on the back of this fictional deal. What did investigators find he actually spent the funds on?
a. Kevin Juin raised money by falsely claiming he was buying Honey Birdette, then spent it on luxury watches, jewellery, private-club memberships, and OnlyFans subscriptions — a detail that made the story irresistible to business journalists everywhere. The scam is a textbook example of affinity fraud built around a glamorous acquisition story: investors are dazzled by the deal's prestige and skip basic due diligence. It also illustrates how private deals in niche luxury markets can be harder to verify than public-company transactions.
US inflation (the rate at which prices across the economy are rising) hit its fastest pace in three years in April, driven partly by higher energy costs linked to the ongoing conflict with Iran. Which of the following best describes what that means for Federal Reserve (the US central bank) policy expectations?
b. When inflation accelerates, central banks typically respond by keeping interest rates higher for longer — or even raising them — because higher borrowing costs cool spending and slow price growth. The Fed's primary inflation target is 2% annually, so a three-year high in the pace of price rises pushes that target further out of reach. Bond markets reacted by pricing in fewer rate cuts for 2025, which raises borrowing costs for everything from mortgages to corporate loans.
New York City recently passed a 'pied-à-terre tax' on second homes — properties owned by wealthy people who live elsewhere most of the year. The tax targets luxury real estate left largely empty. Which of these is NOT a commonly cited risk of this kind of policy?
b. A pied-à-terre tax does not directly incentivise developers to build affordable housing — that requires separate planning and subsidy policies. The other two options are genuine concerns: a wave of luxury sell-offs can temporarily distort the market, and wealthy owners frequently use legal structures like shell companies or trusts to reduce or avoid the tax liability, which is why revenue from these taxes often falls short of projections. New York's version is being watched closely by other cities considering similar measures.
Oil prices fell and global stock markets rose recently after reports emerged that the US and Iran had agreed in principle to extend their ceasefire. Why does a US-Iran ceasefire specifically tend to push oil prices lower?
a. Iran is one of the world's significant oil producers and sits on the strategically vital Strait of Hormuz, through which roughly 20% of global oil trade passes. When conflict in the region escalates, traders price in a risk premium — an extra cost reflecting the possibility of supply disruption. A ceasefire reduces that premium, so oil prices fall. Falling oil prices are broadly good for economies that import energy, which is why stock markets in Europe and Asia often rally on Middle East de-escalation news.
Vietnam made a surprising appearance on a global industrial league table this month — not for electronics or textiles, where it is already well known, but for heavy manufacturing. Vietnam ranked 10th in the world for producing which material, with output of 2.1 million tonnes in a single month?
b. Vietnam ranked as the world's 10th largest crude steel producer in April, the first time it has ever reached that position, with monthly output of 2.1 million tonnes. Steel production is a classic indicator of industrial maturity — it requires significant energy, capital, and logistics infrastructure — making Vietnam's entry into the top ten genuinely significant. For comparison, the list is otherwise dominated by China (which produces more than half the world's steel), India, Japan, and the US, so Vietnam is punching well above its traditional economic weight.
Steel just featured in our quiz, so here's a related geography question. Which country is the world's largest producer of iron ore, the raw material used to make steel?
c. Australia is the world's largest exporter and producer of iron ore by volume, with its Pilbara region in Western Australia home to some of the largest mines on Earth. Mining giants Rio Tinto, BHP, and Fortescue all operate major Pilbara operations. Australia exports the vast majority of its iron ore to China, which then smelts it into steel — making the Australia-China iron ore trade one of the most important bilateral commodity flows in the global economy, worth tens of billions of dollars annually.
One of history's most influential economists published a book in 1776 — the same year as the American Declaration of Independence — that became the founding text of modern economics. Who wrote 'The Wealth of Nations'?
b. Adam Smith, a Scottish philosopher, published 'The Wealth of Nations' in 1776, introducing ideas like the division of labour and the 'invisible hand' — the notion that individuals pursuing self-interest in free markets can, unintentionally, produce good outcomes for society as a whole. The book is often cited as the origin of economics as a formal discipline. Smith also wrote 'The Theory of Moral Sentiments', which argued that empathy and social bonds are essential to a functioning society — a side of his thinking that tends to get less airtime than the free-market ideas.
