Why is GM stock down?

GM fell 8.2% over five trading days, closing at $77.09 on Oct. 20, 2026. A drop like this raises a question: is the problem GM or the whole group it trades with?

We answer that by comparing GM with its closest peers. We also check the calendar for earnings and Fed dates, then review General Motors Co's latest SEC filings and insider trades.

The chart below tracks GM's daily closing price from April 24, 2026 to Oct. 20, 2026. It fell 0.8%, from $77.72 to $77.09. The high was $90.12 on July 28, 2026, and the low was $72.32 on May 19, 2026. Red circles mark weeks when insiders sold shares on the open market (6 weeks; bigger circles mean more money).

What could be behind the GM move

We found no General Motors Co earnings report in the last 10 days or the next three weeks. We also saw no notable SEC filing in recent weeks. Nothing company-specific on the public record explains the move on its own.

The broader market shows a calm uptrend, with the VIX volatility index at 18.44. The Federal Reserve's next rate decision comes on Oct. 28, 2026, 7 days away. Market pricing puts the odds at 86% for a hold, 13% for a hike and 1% for a cut.

What would change the picture for GM

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. It would show up on SEC Form 4 within two business days.
• Analyst ratings: the average score moved from 3.95 to 4.05 over three months. On that scale, 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 $90.12 would mark a new 52-week high, 16.9% above the latest close of $77.09. A close below $57.5 would mark a new 52-week low, 25.4% below it.
• Growth: revenue fell 0.3% year over year in the quarter ending Sep 2026 (trend: accelerating). At a P/E of 16.8, a slowdown would matter more than at a lower multiple.
• New shares: dilution risk is low now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.

How GM compares with its peers

Over the past month GM ranks 3 of 5 in this group (-8.2%). TSLA was best at -0.4%, and LCID was weakest at -24.0%.

GM's P/E of 16.8 sits below the peers' median of 346.0. 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. It has no P/E.

Since 2023, GM fell 8.2% or more in a month 11 times (separate episodes, not counting the current one). Three months later it was higher in 9 of 11 cases; the median change was +14.8%.

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.

52-week high / low

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

Analyst consensus
