AI data movement requires far more capacity than copper interconnects can handle, so optical/CPO connectivity is becoming the consensus.

Overall market valuation is fair and calm, but intra-market dispersion and individual stock volatility are high. For investors uncomfortable with that volatility, steadily accumulating broad ETFs like SPY or QQQ is a viable strategy.

The Magnificent Seven underperformed year-to-date due to profit-taking and rotation into old economy stocks, but strong earnings growth, upcoming big-tech earnings releases, and their role as AI beneficiaries will drive their recovery from July onward, making them a buy after the recent pullback.
