Ross Stores (ROST) Stock Jumps ~5%: A Big Q2 Beat and +10% Comps — With a One-Time Tariff Boost

Ross Stores jumped about 4.8% to roughly $240 on August 21 after a strong fiscal Q2: earnings of $2.66 a share beat the ~$1.94 consensus, revenue rose 13% to $6.26 billion, comparable-store sales grew 10% on higher traffic, and management raised full-year EPS guidance to $8.61–$8.77. The catch: a one-time tariff refund (~$253 million, ~$0.60 a share) flattered the headline — of the 610-basis-point operating-margin expansion, about 405 bps was the refund, and ex-refund EPS was closer to $2.06 (still a beat, but a much narrower one). It was a healthier report than Walmart's, which beat but fell on slowing comps; Ross's +10% comp, though down from +17% in Q1, was far better. And it outran its direct off-price peer TJX (~flat), marking the move as mostly company-specific — though Target's ~4% rally showed the retail tape wasn't uniformly flat. After a ~64% run to near its highs, the stock trades ~28x forward — rich for retail.

Tesla (TSLA) Stock Jumps as Nevada Approves Up to 5,000 Robotaxis, Feeding the Autonomy Premium

Tesla rose about 4.5% to roughly $360 on August 21 (as much as ~5.5% intraday) after the Nevada Transportation Authority unanimously cleared it to operate up to 5,000 paid robotaxis in the Las Vegas area — up from a 10-vehicle cap days earlier. It matters because Tesla is priced as an autonomy platform, not a carmaker: net income is down ~35% year over year on a ~4% trailing operating margin, yet the stock trades near 358x trailing and 181x forward earnings. The same approval moved Uber under 2% (cleared for 1,000) and was immaterial to Alphabet's Waymo — the size of Tesla's reaction is the autonomy premium in action. Wall Street is split like almost no other mega-cap: an average target near $395 but a range from about $25 (GLJ's Gordon Johnson, Sell) to $600 (the Street high). It is a permit, not paid rides — one catalyst among several, and a real step forward with a long way still to travel.

Coinbase (COIN) Stock Jumps ~7%: A Bitcoin Rebound, Treasury Buybacks, and the CLARITY Act

Coinbase jumped about 7% to roughly $171 on August 20 — part of a ~17% two-day surge — as several forces pulled together: a genuine Bitcoin rebound (up ~3.5% to ~$71,500), a U.S. Treasury buyback move that eased yields, short-covering, and a White House crypto event where President Trump pushed the CLARITY Act — a tailwind uniquely relevant to the largest U.S. exchange. The high-beta crypto stocks outran the coin (COIN ~+7%, MSTR high-single digits vs Bitcoin ~+3.5%), magnifying the bounce. It landed on a beaten-down, loss-making stock (down ~43% over 52 weeks, a $359M Q2 loss), so the snap-back was sharp. Wall Street stays net-bullish (Buy consensus, ~$196 target), but targets have been falling and the move rests partly on a crypto rebound and a bill that still faces a mid-September Senate vote.

Deere (DE) Stock Jumps ~9%: A Q3 Beat, a Called Ag-Cycle Bottom, and a Data-Center Construction Tailwind

Deere jumped about 9% to roughly $634 on August 20 after fiscal Q3 earnings of $5.10 a share beat the ~$4.70 consensus and it raised the low end of its full-year net-income guidance to $4.75–$5.0 billion — but the real catalysts were underneath: CEO John May called 2026 the bottom of the multi-year farm-equipment downcycle, and the Construction & Forestry segment surged (net sales +18%, operating margin up to 12.1% from 7.7%) on higher volumes and strong infrastructure, data-center and energy demand. It was the mirror image of Walmart, which beat on EPS but missed on comps and fell ~9% the same day — Deere surprised a skeptical, Hold-heavy Street, while Walmart disappointed a bulled-up one. After a ~30% run in 2026 to near its high, the rally left the stock within about 2% of the ~$645 consensus target, at ~28× next-year and ~35× trailing earnings still below year-ago levels — leaving the fiscal-2027 order book as the swing factor.

Walmart (WMT) Stock Falls ~9%: A Beat-and-Raise, Slowing Comps, and Tariff-Boosted Profit

Walmart fell about 9% to roughly $104 on August 20 despite beating on earnings ($0.81 vs $0.74) and revenue and raising its full-year sales outlook — a classic 'beat-and-raise the market sold.' Three things drove it: U.S. comparable sales grew just 2.6% (the slowest in roughly six years and below the ~3.8% consensus), the profit beat got a one-time boost from a ~$2.9 billion tariff refund (though underlying operating profit still grew near the top of guidance), and Walmart guided third-quarter EPS lower ($0.62–$0.64) as it reinvests the windfall into lower prices. Against a demanding mid-30s forward multiple on a ~3%-net-margin retailer, that mix was too much — even as the broad market was barely changed on the day. It is also the market's clearest read that the U.S. consumer is cooling.

Newmont (NEM) Stock Jumps ~7%: A Gold Surge, a $6B Buyback, and the Barrick Settlement

Newmont was up about 7% intraday, to roughly $124, on August 19 as gold surged toward ~$4,500 an ounce (after a U.S. Treasury move to buy back longer-dated debt lowered yields and the dollar) and the whole mining group rallied — the same group had already jumped ~20% in an August 3–7 breakout week. Newmont carries two extra layers: record free cash flow (~$9.7B trailing, a 55% operating margin, a net-cash balance sheet and a new $6B buyback), and a just-settled multi-year Barrick dispute over Nevada Gold Mines — Newmont agreed to pay $1.95B to fold in prime deposits, and the initial reaction favored it as Barrick fell ~6%. The paradox: after an ~80% one-year run, NEM still trades at only ~11.5× forward earnings, reflecting the market's assumption that high gold won't last. Analyst targets from $67 to $170 are really a bet on the gold price.
