S&P Global, Inc. SPGI

Fair Isaac (FICO) stock fell 27% in the past month with no company news to explain it. Equifax and TransUnion fell more than 20% too. If you hold the shares, you may wonder what a full market shock would do to them. Fair Isaac's record in past shocks can size the next fall, but only if the company that fell then is yours. So is today's Fair Isaac the same company that fell in past shocks.

Bloom Energy (BE) earned nearly 90% of its latest quarterly revenue from selling its power equipment. In fiscal Q2 2026, a record quarter for the company, those equipment sales reached $935 million. Over the past year, the stock returned 314%, against 16.8% for the S&P 500. A stock that has run this far would be exposed if those sales slowed. Should investors in Bloom Energy worry that its record quarter came mostly from one kind of sale.

Johnson & Johnson (JNJ) stock returned around 52% in the twelve months, against 17% for the S&P 500. A $10,000 holding became about $15,220. Over that period, J&J’s revenue growth accelerated even as the company navigated the anticipated loss of exclusivity and biosimilar erosion for STELARA. If that shift showed up in J&J's calls and filings first, a reader could have spotted it early. So was J&J's run in plain sight before it began.

Autodesk (ADSK) stock has lost 22% over the past month following its recent earnings release, outstripping declines in peers such as Bentley Systems (down 16.4%) while the S&P 500 barely moved. If you own the shares, the worry now is a market-wide sell-off landing on top of that loss. So how low could Autodesk stock go if the whole market turns.

Vertiv (VRT) stock trades at 55.1 times earnings, against 21.9 for the S&P 500. At that price, investors expect years of fast growth from AI data centers. For that to hold, customers have to keep placing large orders, and Vertiv has to ship what it has sold. Management used to give you a hard figure on that demand. By the July call, it led with other numbers. So what did Vertiv's management use to put first.

Caterpillar (CAT) owners watched the stock rise 2.3% in the last five sessions while the S&P 500 fell 1.2%. If the rest of your money follows the market, Caterpillar's moves on ordinary market days matter more than one good week. So is Caterpillar stock increasing your market risk.

Lululemon Athletica (LULU) stock offers a free cash flow yield of 12.4%, against 4.5% for the median S&P 500 company. Such a yield usually comes either from a business on sale or from one the market expects to shrink. So can you count on the cash behind Lululemon's yield.

Costco Wholesale (COST) stock rose 2.9% in the first session after its Q4 FY2026 report. The shares trade at 46.4 times earnings, more than twice the S&P 500's 21.9, so holders are counting on growth that keeps coming. What should a Costco holder take from a quarter that beat estimates and lifted the stock, yet left questions about whether its price cuts are driving more sales.

AppLovin (APP) holders have been through a rough stretch. The shares lost 54% over the past year, while the S&P 500 gained 16.8%. A $10,000 holding from a year ago is now worth about $4,560. In September, law firms began announcing a securities class action over what AppLovin told investors. For you, the bigger issue is a business problem, not the legal fight. So what is the biggest risk for AppLovin stock from here.

You may own CrowdStrike (CRWD), a cybersecurity company whose shares rose 5.1% in five sessions as the S&P 500 fell 1.2%. You likely hold it beside an index fund, and your whole account swings more when one holding jumps. Have the gains on CrowdStrike been big enough to pay for those swings.

Fair Isaac (FICO), the maker of the FICO Score, beats Equifax, TransUnion and three other peers on revenue growth and operating margin. Yet its stock lost 59.3% over the past twelve months, the worst return in the group. So after that fall, is Fair Isaac stock worth more than its competitors.

PTC (PTC) and Fair Isaac are both owned for software that customers find hard to replace. PTC sells more to manufacturers it already serves, while Fair Isaac has raised the price of its mortgage credit score. Fair Isaac stock has lost 46% in a month, while PTC stock has lost 12.5%. Which of the two is gaining the firmer grip on its customers.

Merck (MRK) stock returned 96% in the past twelve months, against 16.8% for the S&P 500. With the shares 4.0% below their 52-week high, you need a reason Merck can keep growing. In its fiscal Q2 2026 call, management looked past its best-selling drug to newer ones. So what is Merck stock's biggest opportunity from here.

For five years, the home improvement giant showered its owners with cash, yet the stock itself fell behind. Here's what that trade-off actually delivered.

Arista Networks (ANET) stock costs 63.2 times earnings, against 21.9 for the S&P 500. You can be paid now to agree to buy the shares at a much lower price. So how much income can you earn this way, and would you be glad to own Arista at that price.

On August 4, 2026, Advanced Micro Devices (AMD) guided third-quarter revenue to about $13 billion, above its $11.2 billion second-quarter guide. AMD stock has gained 25.4% since the August 3 close, the day before that release, against 0.9% for the S&P 500. Many rallies have no new company numbers behind them, so one backed by a higher forecast is worth a look. Below we look at AMD's new guidance, its share price trend, and what could lift the stock further.
