Why was QCOM stock down, and why is it rising today?

QCOM is down 5.3% over five trading days, closing at $173.19 on Nov. 4, 2026. When a stock drops like this, the first question is whether the problem is the company or the whole group it trades with.

To answer that, we compare QCOM with its closest peers, check the calendar for earnings and Fed dates, and go through Qualcomm Inc's latest SEC filings and insider trades.

The chart below tracks QCOM's daily closing price from May 11, 2026 to Nov. 4, 2026. Over that stretch it is down 26.4%, from $235.35 to $173.19, with a high of $248.71 on May 29, 2026 and a low of $146.81 on July 31, 2026. Each red circle marks a week in which company insiders sold shares on the open market (13 weeks in this period; bigger circles mean more money). There are no green diamonds: no insider bought on the open market in this window.

What could be behind the QCOM move

We found no Qualcomm Inc earnings report within the last 10 days or next three weeks, and no notable SEC filing in recent weeks, so nothing company-specific on the public record explains the move on its own.

Across the broader market, the backdrop is an uptrend under stress, with the VIX volatility index at 20.83. The Federal Reserve's next rate decision is on Dec. 9, 2026, 34 days away; market pricing puts the odds at 20% for a hold, 79% for a hike and 1% for a cut.

What would change the picture for QCOM

These are the specific events and levels to watch. None of them is a prediction.

• Insider buying: none on the open market in 90 days. A purchase by an executive or director would be the first in at least three months, and it would show up on SEC Form 4 within two business days.
• Analyst ratings: the average score moved from 3.37 to 3.45 over three months (on a scale where 5 is strong buy and 1 is strong sell). A run of downgrades after earnings usually shows up here first.
• Price levels: a close above $248.71 would be a new 52-week high, 43.6% above the latest close of $173.19; a close below $122.93 would be a new 52-week low, 29.0% below it.
• Growth: revenue fell 2.6% year over year in the quarter ending Sep 2026 (trend: slowing). At a P/E of 13.6, a slowdown would matter more than at a lower multiple.
• New shares: dilution risk is moderate now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.

How QCOM compares with its peers

Over the past month QCOM ranks 1 of 6 in this group (-4.3%); the best was QCOM (-4.3%) and the weakest INTC (-48.2%).

QCOM's P/E of 13.6 is below the peers' median of 33.8, so investors pay less for each dollar of its profit.

A dash in the P/E column means the company lost money over the last 12 months, so it has no P/E.

QCOM history: what happened after similar moves

Since 2023, QCOM fell 10% or more in a month 11 times (separate episodes, not counting the current one). Three months later it was higher in 4 of 11 cases; the median change was -4.0%.

Past moves don't predict the next one; they show how volatile the stock has been.

Key terms on this page

P/E ratio

Form 4

The SEC form a company's officers, directors and 10% owners must file within two business days of buying or selling its stock.

Open-market trade

A purchase or sale on the exchange at the market price, paid with the insider's own money (code P or S on Form 4), as opposed to option exercises, grants or gifts.

Form 13F

A quarterly SEC report listing the U.S. stock holdings of every investment manager with more than $100 million. It is due 45 days after each quarter ends, so it shows positions with a delay.

Dilution

When a company issues new shares, each existing share owns a smaller piece of the company. Common sources: stock offerings, convertible debt and large stock-based pay.

52-week high / low

The highest and lowest daily closing price over the past year (about 252 trading days).

Analyst consensus

The average of Wall Street analysts' ratings (strong buy to strong sell). Analysts skew positive, so a hold is often read as a cautious view.
