Why is Cisco Systems stock falling today?

Investing.com -- Cisco Systems stock fell 3.0% in pre-open trading today after Morgan Stanley downgraded the networking giant from Overweight to Equal-Weight and reduced its price target to $120 from $135, a move that sent immediate shockwaves through the pre-market session. Morgan Stanley analyst Meta Marshall argued that the stock’s remarkable 43% gain over the past 12 months — far outpacing the S&P 500’s 14% advance — has pushed Cisco’s valuation to roughly 19 times forward earnings, now in line with the broader index and leaving little margin for further re-rating. The firm noted that "strong expectations and gross margin headwinds from AI business leave less room for upside," and flagged that much of the AI-driven expansion is already reflected in the share price.

Beyond the headline rating cut, Morgan Stanley raised concerns about pull-forward demand, warning that some customers may have placed orders early to get ahead of planned price increases, which could flatter near-term results but create a hangover in subsequent quarters. The bank also pointed to a rising mix of lower-margin hardware sold to hyperscalers as a structural drag on gross margins. Adding to the cautious backdrop, recent insider selling activity totaling approximately $6 million over the past three months has reinforced a sense of limited near-term conviction among those closest to the company, while the Marvell Technology–Lumentum $115 billion acquisition announced earlier this week has raised questions about supply-chain diversification for optical components across the networking sector.

The macro and sector environment offered little support today. The NASDAQ composite is down 1.2%, putting additional pressure on high-multiple technology names, while the S&P 500 is barely changed and the Dow Jones is modestly positive, suggesting the selling is concentrated in tech. Cisco’s upcoming fiscal first-quarter 2027 earnings, scheduled for November 12, have raised the performance bar, and recent earnings reactions from networking and cybersecurity peers have underscored how unforgiving the market has become toward any guidance shortfall.

Taken together, a high-profile analyst downgrade citing valuation exhaustion, pre-earnings caution, margin headwinds, and a weak tape for technology stocks have combined to push Cisco shares to $100.55 in pre-market — well below their 52-week high of $130.37 — as investors reassess whether the stock’s premium can be sustained heading into next week’s results.
