I'm Julia Borsden, and you're listening to CNBC's Tech Tech. Our show is live weekdays at 11 a.m. Eastern, Tech Check. I'm Carl Kintania with John Fort and Julia Borsden. Today, tech stocks rally. The NASDAX's on pace for the best day since August, best day for the S&P since July. Then Shopify teams up with Microsoft and Oracle to take on Amazon,

plus LinkedIn shuts down in China. And then later on, LeBron James business partner, Mav Carter. A lot to get to with Mav, John.

Yeah, we're going to start with the chip crunch and supply chain pain. Well, it's not painful for everybody.

It's leading to some strong results for Taiwan Semiconductor, posting a 14% increase in Q3 profits, also upping sales forecast,

expecting growth of 24% this year. Warning, they do expect capacity to remain very tight

know what Apple's got in inventory. And if things pick back up, iPhones are light. They'll be able to, you know,

air freight them pretty quickly without too big a hit to margins, even though it would be a margin

hit. Yeah, easier to ship iPhones than it is to ship peloton. So it'll be interesting to see

how all the supply chain issues play out. But we're also hearing things like taking the LA port here

in my hometown and making that a 24-7 port. And we'll have to see if that kind of announcement

and that kind of news means that we are nearing an inflection point when it comes to the broader

supply chain issues, even just looking beyond chips. But Carl, if you look at the Apple question in particular,

there are so many other factors working in Apple's favor. If you can separate out the supply
