I'm Carl Kintanilla. You're listening to CNBC's Tech Check. Our show is live weekdays at 11 a.m. Eastern. Listen in. Good Friday morning. Welcome to Tech Check. I'm Carl Kintania with John Fort and Julia Borsden. Dear Durbosa is off today. Big question this morning. Is it time to ring the register? Tramath Palahapitia out with some new wards of warning as tech hits record highs, the top performing sector in the S&P right now.

Then we're a week away from Black Friday.

We've got to look inside Amazon and the dark secret about your data.

Finally, don't miss the CEO of Intuit as the stock is surging following those good results.

Shares now up 85% for the year, John.

Yeah, that's Friday.

So let's take a step back and start with the

broader market for tech. Nasdaq, semis, growth names, all continuing to hit all time high after

all time high. So when do you call the top? Chamaupalhappita, just the latest high profile

name to warn investors that a reckoning could be on the way, writing, quote, I find myself with more questions than answers, unquote. That's probably a first for Tchaumov,

Yesterday, it was John Malone and Bill Ackman, warning about bubbles and parallels to 1999. Julia, I adjust somewhat. Chamatha's always been good at asking questions, but he's also known for excitedly, let's say, promoting certain ideas.

Yes, I mean, he was king of the SPACs, or maybe he is still king of the SPACs. I don't know.

Maybe the SPAC market doesn't have a king anymore. But what's so interesting is he was all in on the SPACs and now we're in a different phase. The heat on SPACs has cooled

down. But we are really seeing a divergence within the tech sector. This is something we've talked

about a lot. There are those companies that have been really hurt by supply constraints,

those that have not been able to navigate it. And those that are now feeling the pinch

as the stay-at-home market seems to have waned.

And Carl, I do think that we are seeing some of the high flyers of the past year really come down to earth,

while we still have some of those stocks at these very high valuations, Carl.

Yep. Wells with a note a few moments ago, guys. We've seen a number of recent stories that in time
