Increased AI bear sentiment and rotation into defensives is a contrarian bull signal, not confirmation of a top

The last two weeks I've seen more "AI bubble" posts, YouTube videos, and finance threads than the past six months combined. Traders in my circle are rotating back into dividend stocks and industrials. Defensive portfolios are suddenly cool again.

And I think this is the signal most people are misreading.

Bubbles don't burst when everyone's nervous. They burst when every taxi driver, barber, and college student is leveraged long on the theme. We are nowhere near that. I don't know a single person personally, young or old, who actually holds AI infrastructure names in their brokerage account. Not including indices.

The buildout hasn't happened yet. Data centers, power grids, cooling infrastructure, chip supply chains, we're still literally pouring concrete. The capital expenditure cycle powering this transition is in its early innings. Most Fortune 500 workflows are still running on Excel and email.

Real adoption is sub-single-digit penetration. Ask any mid-size business owner if AI has meaningfully changed their operations. The answer is almost universally no. That's not a bubble popping. That's a technology that hasn't arrived yet.

The internet parallel is worth studying. In 1997 people were calling the internet a bubble. They were wrong, but only by about three years and 400%. The actual bubble came when retail capital flooded in and valuations disconnected entirely from buildout reality. We don't have that yet. Institutional conviction at scale is still forming.

The rotation into defensives this early in the cycle is a contrarian signal, not confirmation of a top. When broad sentiment turns cautious on a structural theme before mass adoption has occurred, historically that has not been the top.

I'm not arguing there won't be volatility. I'm arguing the people calling the top haven't seen the beginning yet.

Positions: MU 12 shares, MRVL 39 shares, SNDK 2 shares. Planning to add GOOGL. Rest of the portfolio is in the same thesis. Long and not moving.
