Technical analysis: the day after the Fed, semiconductor stocks lead the rebound with Arm, Intel and AMD

18 September 2026 AiTrading67 · Trade Desk Observatory Markets

On Thursday 17 September markets absorbed the first US rate hike since 2023. Press reports say the recovery came as oil and Treasury yields fell together, with the ten-year yield back below 5%, and equity volatility dropped almost 13% in a single session. All seven of the main indices we follow closed higher, and Milan posted its second straight gain.

In this edition you will find the technical analysis of the names that made the session, with our model's position on each. On US stocks, semiconductor stocks led the way: Arm stock, Intel stock and AMD stock were among the best of the day, with Nvidia stocks, Amazon stock and Microsoft stocks behind them, while Salesforce and Boeing went the other way. In Europe Rolls-Royce, Siemens Energy and Volkswagen led a broad advance, and on the Milan market Poste Italiane and Telecom Italia topped the list with the banks close behind. Our trading strategy on each name is set out below.

The rebound was sharpest in the stocks sold hardest over recent weeks, and that is where our model held up: the shorts on Rocket Lab, D-Wave and Arm are still well in profit after the session. Every reading comes from a systematic model, that is ai trading applied to about 450 instruments, and they remain references: the choice always belongs to whoever trades.

THE DAY AFTER
After the hike

Wall Street recovers as yields and oil fall together, and the S&P 500 withdraws its weekly reversal

A day after the Federal Reserve decision, US indices won back most of the drop. On our data S&P 500Long, the ETF on the S&P 500, gained 1.13%, Invesco QQQ TrustLong on the Nasdaq 100 rose 1.73% and Russell 2000 ETFShort on small caps 0.53%. Press reports put weekly jobless claims at 196,000, below expectations: a solid labour market, which is also the reason the central bank raised rates in the first place.

The rebound ran on almost a single engine. US technology, US technology ETFLong, gained 2.25%, followed by consumer discretionary at 1.10%; communication services, US communication services ETFLong, lost 0.58% and financials, US financials ETFLong, were flat. Equity volatility fell 12.8% and bond volatility 5.6%.

How I read itThe number that matters for our model sits on the S&P 500. On Wednesday the weekly candle carried a sell reversal by 0.04%; on Thursday the week's typical price climbed back 0.34% above the level of the long trade opened on 6 April. The reversal has been withdrawn, and the trade is still more than 12% in profit. On the Nasdaq 100 the daily signal turned back to a buy and lined up with the weekly. The reversal on US financials is still open, 0.42% below its starting level: for risk management, the week is settled by today's close.

TECHNOLOGY
Chips lead the recovery

Semiconductor stocks on top: Arm, Intel, AMD and Micron drive the rebound, with Nvidia, Amazon and Microsoft

Semiconductors were the strongest group of the session: Arm stockShort rose 8.57%, Intel stockShort 7.67%, AMD stockShort 6.36%, Micron stockLong 5.50% and Super MicroLong 9.50%. Among the megacaps Nvidia stockLong gained 2.54%, Broadcom stockShort 2.29%, Amazon stockShort 2.13%, Microsoft stockLong 1.52%, Meta stockLong 1.34% and Alphabet stockShort 1.30%. OracleLong added 5.19% and DellLong 4.46%.

Not everything in the sector joined in. CoreWeaveLong fell 4.16%, Salesforce stockLong 3.07% and NetflixLong 1.44%, on a day when technology as a whole was up 2.25%.

How I read itOur model has long-standing positions here, and the oldest are the strongest: long Dell since 23 February, with a gain that has almost quadrupled the entry price, Salesforce since 27 July at 31.97% even after a down day, Microsoft at 7.11% and Meta at 5.29%. On the short side Arm stocks are still 15.98% in profit after yesterday's 8.57% jump, Alphabet 3.43% and Broadcom 2.96%. The chip rally did work against our shorts on Intel stocks and AMD stocks. The session's price action trading picture is a concentrated rebound: technology carried almost all of the S&P 500's gain, and Nvidia stocks and Microsoft stocks did their share.

WALL STREET
The hardest hit bounce

Quantum computing, solar, space and crypto: FuelCell, IonQ, D-Wave, First Solar and Coinbase rebound, Boeing slips

The session rewarded above all the stocks sold hardest in recent weeks. FuelCell EnergyShort rose 14.26%, IonQ stockLong 9.50%, D-WaveShort 8.73%, Rocket Lab stockShort 6.47%, First Solar stockShort 5.28% and Archer AviationShort 3.45%.

In crypto, after the blow on decision day, Coinbase stockLong recovered 5.75%, RobinhoodLong 5.16% and StrategyLong 4.81%; press reports say bitcoin held the 76,000 dollar area. Boeing stockShort went the other way, down 2.46%.

How I read itThis is a case where a strong bounce does not change the reading. Our model has been short these names for months, and the positions are still in profit after the session: Rocket Lab up 38.39% since 1 June, D-Wave 11.95%, FuelCell 4.24%, First Solar 1.61%, Archer 3.23%, and Boeing 6.11%. On the long side Robinhood is up 5.32% and Strategy 3.88%. For swing trading, a 9% bounce on a stock with a weekly sell reads as short covering until the weekly turns: the daily buy fired on many of them, but against the weekly.
FuelCell Energy short (G / P) · IonQ long (G / P) · D-Wave Quantum short (G / P) · Rocket Lab short (G / P) · First Solar short (G / P) · Archer Aviation short (G / P) · Coinbase Global long (G / P) · Robinhood Markets long (G / P) · Strategy long (G / P) · Boeing short (G / P) *

Poste, Telecom and the banks

Milan market: Poste Italiane and Telecom Italia on top, Stellantis, A2A and Fincantieri higher, banks up again

On our data Poste ItalianeShort gained 3.40%, Telecom ItaliaLong 2.98%, FincantieriLong 2.40% and Stellantis stockShort 2.26%. Utilities rose with HeraShort up 1.98%, Enel stockShort 1.71% and A2ALong 1.28%; fashion did well with Brunello CucinelliShort up 1.63% and MonclerShort 0.55%.

On Intesa Sanpaolo stock the price has been closing in for two sessions on an entry zone the desk has been watching for days. We are also long Fincantieri at 8.55% and A2A, where the daily buy fired on Thursday on top of a weekly structure already in buy mode. On the short side Stellantis is still 24.72% in profit and Moncler 15.57% after the rise. Poste has been a short since early September, and yesterday's jump went against it.

EUROPE
London and Frankfurt lead

Europe: Siemens Energy, Volkswagen and Rolls-Royce lead the rise, AstraZeneca and HSBC higher, EssilorLuxottica and Deutsche Telekom lower

Every major European market closed higher. On our data Siemens EnergyShort gained 3.41%, Volkswagen stockLong 2.74%, Rolls-Royce stockLong 2.72%, AstraZeneca stockShort 2.41% and SiemensShort 2.34%. Banks rose too, with HSBCLong up 1.96% and Deutsche Bank stockLong 1.83%, as did German carmakers, Mercedes-BenzLong up 1.83% and BMWLong 1.74%, and GlencoreLong 1.63%.

How I read itOn the fallers our model already had the right reading: short EssilorLuxottica since last December at 49.86%, Infineon at 14.55%, Adidas at 10.66% and Thales at 2.62%. On the long side the April positions keep working: Allianz 19.56%, SAP 19.23%, Deutsche Bank 18.45%, HSBC 14.71%, Rolls-Royce 12.91%. Siemens Energy, a short since June, is still 10.26% in profit after the day. Volkswagen and BMW have been longs since late August and sit roughly flat.

INDICES
Four gains, two structures

European indices: four baskets higher, Milan turns to a daily buy, Frankfurt decides today

On Thursday the FTSE MIB ETF FTSE MIB ETFShort gained 0.79%, the DAX ETF DAX ETFLong 0.67%, the CAC 40 ETF CAC 40 ETFShort 0.66% and the FTSE 100 ETF FTSE 100 ETFLong 0.46%. A second day of gains for all four, with Milan still in front.

Beneath the rise the structures remain split. Milan has been a sell since the week ended 4 September, with the typical price of the forming week 2.94% below its level; on Thursday, though, its daily signal turned to a buy for the first time since mid-August. Paris has been a sell since 24 August, 2.76% below its level. London remains a buy since April, 0.58% above. Frankfurt, a buy since April, carries a sell reversal on the forming candle, with the typical price 0.41% below the level it started from, down from 0.99% on Wednesday.

How I read itThe two baskets on a sell, Milan and Paris, are also the furthest from their records, and their bearish reading is intact: on Paris the sell signal is 2.45% in profit. The open case is Frankfurt, which has closed more than half the gap to the level its reversal started from and can withdraw it tonight. The Signal Strength, which measures a move's conviction and never its safety, is low on all four: a phase where levels matter more than trends.

SOXX — iShares Semiconductor, the semiconductor ETF — gained 3.39%, and XLK — the Technology Select Sector SPDR, the US tech ETF — 2.25%, first among the eleven sectors. GLD — SPDR Gold Shares, the most heavily traded gold ETF in the world — recovered 1.69%. XLE — the Energy Select Sector SPDR, the energy ETF — steadied at 0.70% after Wednesday's drop.

How I read itOn European banks our model has been long since April at 18.81%, and on US energy since 13 July at 11.79%: two weekly trends the Fed's week has not touched. On gold, the sell reversal that appeared on the forming candle on Wednesday has been withdrawn, with the typical price 0.23% above the level. On semiconductors we have been short since 13 July and the rebound has cut the margin to 0.52%; on US technology we are long since August, close to flat. European basic resources have been a long since early August.

OUR MODEL
Seven changes in one session

The new buy signals: Micron, Archer Daniels and Bloom Energy back above entry

The weekly cohort was born at Friday 11 September's close: 15 new buy signals, 10 tradable. From Tuesday to Friday this card publishes only what changes — who crosses above or below their entry level, who flips side on the daily signal, who reports earnings, who leaves the cohort.

Yesterday brought seven changes. Micron stockLong, Archer Daniels MidlandLong and Bloom EnergyLong moved back above their entry levels. Micron, Taiwan Semiconductor stockLong and Nokia stockLong turned their daily signal to a buy, which now stays a sell only on LegrandLong. The other way, Tenaris stockLong and SabespLong slipped just below entry. None of the fifteen reports earnings in the next seven days.

How I read itThe chip session repaired the weakest part of the cohort: three of the four names whose daily signal had turned against them lined up again in a single day, and the two time frames now agree on fourteen names out of fifteen. The best performers remain GameStop stockLong, 7.66% above the signal, and Meta stocksLong, 5.29%. The cohort is judged on tonight's close, and for swing trading the rule is still to scale in.

This week's earnings: Costco on Thursday, Uranium Energy on Friday

Two companies in our universe report between now and next Friday. On Thursday FedEx stockLong released its first fiscal-quarter results with earnings above expectations and closed up 1.38%; Carnival's date has moved to 29 September.

Thursday 24 September

Costco Wholesale Short

Friday 25 September

Uranium Energy Long

How I read itOn Costco stock our model has been short since 26 May at 6.52%, and goes into the report with a gain to protect. On Uranium Energy the forming weekly candle carries a sell reversal, confirmed or withdrawn tonight, a week before the numbers. Our view of earnings is measured: results do not move the average return, they widen the spread of outcomes, and they are a reason to enter with a smaller position.

UNITED STATES
Two baskets realigned

Technical analysis of SPY and QQQ: SPY withdraws its weekly reversal, QQQ turns to a buy on the daily too

S&P 500Long, the ETF on the S&P 500, closed Thursday up 1.13%; Invesco QQQ TrustLong, the ETF on the Nasdaq 100, up 1.73%. Applying each basket's sector weights to the day's sector moves, SPY should have gained 0.93% and QQQ 1.27%: both did better, and technology accounts for 74 basis points of the first and 114 of the second.

On the weekly the two baskets are back on the same side. On SPY the typical price of the forming week rose 0.34% above the level of the long trade opened on 6 April, and Wednesday's sell reversal has been withdrawn; SPY is in its twenty-third week, with every profit-taking window reached. QQQ has its typical price 1.73% above its own level, and on Thursday it turned its daily signal to a buy as well, by just 0.06%.

How I read itThe same composition that shielded the Nasdaq 100 on Wednesday lifted it on Thursday: technology is 50.5% of QQQ and 32.9% of SPY. The upshot is that QQQ has both time frames aligned and SPY does not, because its daily signal is still a sell by 0.21%; SPY, however, sits closer to its record, 2.15% below against 4.24%. Risk management on these two instruments today comes down to two levels: SPY's weekly close above its own level, and QQQ holding its daily turn.

The desk's take

The bigger picture: the day after the Federal Reserve

The market did in one session what usually takes a week: it absorbed the first monetary tightening since 2023 as soon as yields and oil fell together. The recovery was broad across indices, all seven higher, and narrow across sectors, with technology carrying almost all the weight on Wall Street. The most concrete result for our model is the withdrawal of the S&P 500's sell reversal, which removes the week's biggest threat. On the SPY ETF the threat is gone for now. Two things remain to watch: tonight's close, which settles the reversals still forming on US financials and Frankfurt, and participation in the rally, which recovered 2.1% on Thursday but has been falling for five weeks.

What you find here. If you are trying to understand how to manage risk in trading — stops, break-even stops, trailing, and the declaration of stops that have been taken out — or how to read chart patterns (double bottoms, Bollinger bands, the Ichimoku cloud, price action trading), this is the desk's trading journal: published every morning before the US premarket, with our model's position on every instrument mentioned.
