With Cisco Systems up 48.05% over 90 days and 82.56% over 1 year, while showing annual revenue and net income growth, investors now face a simple question: is there still value left, or is future growth already priced in?

The most followed valuation narrative currently puts Cisco Systems’ fair value at $110.56, below the recent $121.15 share price. This frames the recent rally in a very different light.

Another View: Cisco Systems Through the P/E Lens

While the narrative-based fair value for Cisco Systems sits at $110.56, the current P/E of 39.9x tells a more mixed story. It is lower than the 95.3x peer average and close to a 41.7x fair ratio, yet above the US Communications industry at 31x. This raises the question of whether it represents a margin of safety or a valuation risk if growth cools.
