The Real Cause of the Sudden Surge in CIEN | In the AI Data Center Era, the Protagonist Is Not "Computation" but "Optical Communication"

One of the stocks currently at the “center of the market” in U.S. equities is Ciena (CIEN).
It might look like just another AI-related meme stock, but this rise is more structural than that.

There are two key points.
① With the spread of AI data centers, the bandwidth between data centers is exploding.
And② By being included in the S&P 500, index-tracking funds’ rebalancing tends to push on supply and demand even further.
When this “theme × demand” aligns, trading volume surges and stocks tend to take the lead in the market.

But there are cautions as well.
Right now, CIEN is being evaluated more on future earnings potential than on actual results. It’s likely to be evaluated on forward earnings potential.
What to watch isn’t the price alone, butwhether volume normalizes without breaking down / whether the guidance remains sustainable.
