Intel stock dropped 20% and Amazon slid after hours as both companies reported disappointing quarterly earnings, CNBC said on Friday 30 October 2026. Anyone holding INTC or AMZN saw the value of those positions reprice in a single session, with Intel pointing to a PC slowdown behind its weak guidance.
What happened to Intel and Amazon this week?
Two large-cap tech names fell on earnings in the same session. CNBC reported on Friday 30 October 2026 that Intel stock plunged 20%, with the chipmaker blaming a PC slowdown for weak guidance. Seeking Alpha noted on Thursday 29 October 2026 that Intel's Q3 results and guidance missed Wall Street's forecasts.
Separately, Investing.com reported on Thursday 29 October 2026 that Amazon shares slid more than 6% after hours on a quarterly results miss. The same evening, Seeking Alpha reported that Starbucks posted a revenue miss that overshadowed solid fiscal Q4 results, though it paired that with upbeat profit guidance.
Beyond those points, specifics are not yet confirmed. The exact revenue figures, the precise forward numbers Intel gave, and the detail behind Amazon's miss are not spelled out in these reports, so this article will not invent them.
What the headlines do and do not tell us
- Confirmed: Intel fell 20% on a guidance miss tied to a PC slowdown.
- Confirmed: Amazon fell over 6% after hours on a quarterly miss.
- Confirmed: Starbucks missed on revenue but guided profit upbeat.
- Not yet known: the underlying dollar figures, segment detail, and how much of each move holds once regular trading settles.
Why do earnings guidance misses move a stock so sharply?
A guidance miss moves a stock because share prices reflect expected future results, not just the quarter just reported. When a company like Intel tells the market its coming quarters will be weaker than analysts modelled, the market reprices those future earnings immediately, which is how a single afternoon can erase a fifth of a company's value.
That is the mechanical reason a 20% plunge can follow results that, on their own numbers, may not look catastrophic. The gap between what was expected and what was guided is what gets priced, not the absolute figure.
- Revenue miss means sales came in below the consensus estimate.
- Guidance miss means the company's own forecast for the next period is below what analysts had penciled in.
- Mixed results, as with Starbucks, can leave a stock pulled in two directions at once.
How can I check my exposure to Intel and Amazon right now?
Check exposure by finding every place these names sit in your holdings, including inside funds you may not think of as tech. A direct INTC or AMZN position is obvious, but an S&P 500 ETF, a Nasdaq-100 fund, or a semiconductor ETF can carry meaningful weight in the same names.
If your holdings are scattered across more than one broker, a single combined view matters here. The ALL PORTFOLIOS view in PortfolioTrackr sums the same ticker across every account, so you see your total AMZN or INTC position in one line rather than hunting through separate apps. This is the same reason many investors moved off spreadsheets, as covered in our comparison of portfolio trackers versus spreadsheets.
Direct holdings versus fund holdings
- Direct shares: search your portfolio for INTC and AMZN and read the current value and unrealised P&L line.
- Index funds: large-cap US index funds hold both names; the weight shifts as prices move.
- Sector funds: semiconductor and megacap-tech ETFs concentrate the exposure.
Checking is not acting. Knowing your real number is simply the input you need before you decide anything for yourself.
Do foreign holders of Intel or Amazon face a currency effect too?
Yes, if you bought US shares in a non-US currency, the dollar move sits on top of the share-price move. A holder in euros, pounds or rupees sees both the stock drop and the day's exchange rate change reflected in home-currency value.
PortfolioTrackr separates these two effects so you are not guessing which part of a loss is the stock and which is the currency. It converts the cost of a holding at the exchange rate of the day you bought it and the value at today's rate, then shows the currency gain or loss as its own line on the summary card and the P&L chart. If you hold US tech from abroad, that split tells you how much of this week's move is really about Intel and how much is about the dollar.
How do I set a price alert on Intel or Amazon?
Set a price alert by adding the ticker to a position or watchlist and choosing a level: Target 1, Target 2 or a stop-loss on a holding, or a price above or below on a watchlist entry. PortfolioTrackr checks each level once a minute while the market is open, and around the clock for crypto, so you hear within a minute of your level being hit.
Alerts are price levels only. There is no earnings alert or news alert, so an alert will not have warned you about Thursday's reports in advance; what it does is tell you when INTC or AMZN reaches a number you chose yourself.
- Watchlist alerts work without owning the stock, useful if you are only tracking the move.
- Delivery by email, WhatsApp, Telegram and push is on every plan; SMS is Pro and Lifetime only.
- Status, not advice: PortfolioTrackr reports whether a level is still below target or reached, and never tells you to buy or sell.
The watchlist and its price alerts are on every plan, with 10 tickers on the free trial and Starter and 50 on Pro and Lifetime.
Should I review my overall tech allocation after a day like this?
Reviewing your allocation means looking at how much of your total portfolio sits in a single stock or sector, which is a fact you can read, not a decision anyone should make for you. After a sharp move, the weight of the names that fell has shrunk, which can change the shape of your portfolio without you trading at all.
Here is a simple, advice-free comparison of what you can and cannot check inside a tracker like PortfolioTrackr during an event like this.
| Question | Can a tracker answer it? | How |
|---|---|---|
| What is my total INTC exposure? | Yes | ALL PORTFOLIOS combined view |
| How much is currency vs stock? | Yes | Separate currency line on the summary card |
| Where does AMZN sit vs my targets? | Yes | Status against your own Target/stop levels |
| Should I buy or sell now? | No | That is your decision, not the app's |
If you want the mechanics of pulling every account into one place first, our guide on connecting a brokerage account to a portfolio tracker walks through it, and broker sync is optional since manual entry, CSV and screenshots work on every plan.
What should investors watch next on this story?
Watch for the detail that these first headlines did not carry. The regular-session reaction, the full guidance numbers, and management commentary on the PC slowdown Intel cited will all shape whether Thursday's moves hold or fade.
- Regular-session trade: after-hours and first-reaction moves often differ from where a stock settles.
- The actual figures: the revenue and forward numbers behind the 20% Intel drop and Amazon's 6% after-hours slide.
- Read-across: whether other chip and megacap-tech names move in sympathy. Our rundown of the 29 October earnings slate lists who else reported into this window.
Until those details are confirmed, treat the single confirmed facts as the facts: Intel fell 20% on a guidance miss, Amazon slid over 6% after hours, Starbucks missed on revenue but guided profit upbeat.
The bottom line
Intel's 20% plunge on a PC-driven guidance miss and Amazon's 6%-plus after-hours slide, both reported this week, are a reminder that earnings reprice the future, not just the past quarter. The practical steps for a holder are to check total exposure across accounts, know how much of any loss is stock versus currency, and set a price alert at a level you choose.
None of that is a trade instruction. PortfolioTrackr shows you where you stand against your own targets and leaves the decision where it belongs, with you.

Frequently asked questions
How much did Intel stock drop this week?
Intel stock plunged 20%, CNBC reported on Friday 30 October 2026, after the chipmaker issued weak guidance it blamed on a PC slowdown. Seeking Alpha reported the same week that Intel's Q3 results and guidance both missed Wall Street forecasts. The full underlying figures were not detailed in these first reports.
Why did Amazon shares fall after earnings?
Amazon shares slid more than 6% after hours on a quarterly results miss, Investing.com reported on Thursday 29 October 2026. The headline does not spell out the exact figures or segment detail behind the miss, so the precise cause beyond a quarterly results miss is not yet confirmed from these reports.
How do I see my total exposure to a stock across brokers?
Use a combined view that sums the same ticker across every account. PortfolioTrackr's ALL PORTFOLIOS view adds up your total INTC or AMZN position in one line instead of checking separate broker apps. It is available on every plan for anyone with more than one portfolio.
Can a portfolio tracker alert me when a stock hits a price?
Yes. PortfolioTrackr checks each price level once a minute while the market is open, and around the clock for crypto, so you hear within a minute of your level being hit. Alerts are price levels only: Target 1, Target 2, a stop-loss, or a watchlist price above or below.
Does a tracker tell me whether to sell after an earnings miss?
No. PortfolioTrackr reports status against your own levels, such as whether a stop-loss level is reached, but it does not give buy or sell advice. It shows your exposure and where a position sits versus targets you set, leaving the decision entirely to you.
