TSM
Taiwan Semiconductor Manufacturing Company Ltd.
stock NYSE ADR

Is this a worthwhile portfolio to invest big in. Besides the heavy tech imbalance. Seems very balanced and not too volatile.
I went for BrkB for Oxy/Apple exposure too. Oxy would be nice for more oil in the portfolio for more volatility.

By the time it actually shows the weakness you are way too late. People analyzing stocks are talking to industry insiders, analyzing supply chains, reading think tank reports etc. The semi industry started dropping in Jan 2022, that was way before demand decline hit their income statement. Sure enough though, TSM had a down year in 2023.

The core and satellite strategy is pretty common and does make sense - it lets you reasonably make individual stock bets without giving up the benefit of ETFs entirely. Around half my international holdings are split between two ETFs with the other half being individual holdings(of which ASML and TSM are also on my personal list). My small-mid cap holdings similarly have AVUV to cover the small cap because I haven't quite got a handle on a statistically viable strategy there yet, and my mid caps are 12 individual companies, which has been working pretty well for me. My large cap holdings are entirely individual stocks for my taxable account - it's tech heavy at the moment but I'll be shifting in the coming weeks as the market direction develops.
Suffice to say this past month was one of my best. So yes, the satellite approach works splendidly. To answer your questions in order though:
1. Yes
2. You already hold the S&P500 which has an overlap with NDX of around 80% by weight, so that should be fine.
3. Diversification is protection against ignorance, not the inarguable best investment strategy. If you think it's a good bet, go for it.
4. Those are three extremely good companies. I own them and don't feel much concerned about sector risk. I've also been making good $$$ off of my holdings in MU, AMAT, AMD, and LRCX, which I will be trimming - I will be leaving NVDA, ASML, and TSM untouched. Take that for what you will.
5. If you find good non-tech stocks. I find including something for the sake of including it to be a mis-appropriation leading to wasted opportunity cost. For anything you buy, be it an ETF, or individual stock, ask yourself: "is this going to get me a better risk adjusted return than putting this cash into the S&P500?" I find that tends to make it easier. If the answer is no, SPYM and chill.
Anyway that's all I got for you. Your plan isn't crazy. If anything my plan is nuts in comparison consisting of around 40 companies, even if they are spread across a wide array of market caps, sectors, and countries. It works for me though and I enjoy running it.

It's hard to know though. Historically, technology gets integrated slower than people think, but AI's improvements have been remarkable, especially Mythos. Even if you don't buy the hype comments, its benchmark performance is pretty incredible. I would just much rather own a business like TSM supplying the AI revolution than software facing a potentially existential threat unless I had a great inside view as to why AI will fail.

TSM, when it was under $150 a share last year.

VOO VXUS AVUV URA & up to you to add TSM, split it 60/20/10/10 or 5/5, I've had great returns from this setup

NVDA, GOOG, TSM, AMZN

Calls printed this morning for TSM, Nvidia, and SPY. Sold 5 TSM 175C for 1.10, bought at 0.40. Sold my SPY 703C for 4.50, bought at 1.38. Sold my NVDA 200C for 2.50 bought at 1.10. Left money on the table but since ive switched my mindset from "This can go higher" to "I am up \*\*\*% I should take profit" Trading has become so much less stressful. Waking up and being up 17% on my account in the first minute of the day and staying out the rest of the day was a good way to start my friday.

Mu and TSM destroying my early gains

Welcome to the journey — a few thoughts re: QQQM that I learned the hard way.
VOO already holds about 87% of what QQQM holds, with roughly 48% weight overlap between the two. And VOO is already \~32% tech by weight, which is historically quite concentrated — so adding QQQM on top of VOO isn't really diversification.
Which raises the question: why are you wanting QQQM? If it's for an intentional tech tilt, QQQM may not even be the best choice for that. It tracks the 100 largest Nasdaq-listed companies — not tech companies specifically — so you also get Costco, PepsiCo, Moderna, and Booking Holdings sneaking in through the Nasdaq listing backdoor. If you genuinely want concentrated tech exposure, VGT or IGM give you purer tech with less dilution from consumer staples, biotech, and travel companies. SMH is also a solid tech play — it's thematically narrower (semis), but it's the "picks and shovels" of the AI buildout (that is, all the money that the hyperscalers are spending to buildout the AI infrastructure? it's going to the picks and shovel companies). SMH also holds TSM, a monopoly essential to the AI buildout that is not in either QQQM or VGT.)
Another reason why some people hold QQQM is to blend your performance between the S&P and the Nasdaq, which can be psychologically helpful. But even this logic gets a bit complicated — QQQM is the top 100 of the Nasdaq, not the full composite, so it actually runs higher beta than one might expect.
For actual diversification that complements VOO in a meaningful way: VXUS is genuinely uncorrelated international exposure, and SCHD adds a value/dividend tilt that VOO completely lacks. Those two actually add something new to the portfolio. QQQM mostly just adds more of what you already have — which may be fine if that's what you want. (I hold several ETFs, even though they overlap, because I want to add weight to certain holdings.)

MM shook out TSM option holders and now buy it back up. Idiots. AI IS DEAD.

Are you talking about TSM? would love to know who the big winners might be

They design their own chips on the ARM Architecture and use TSM to produce them. Intel design their own chips on the x86 architecture which they and AMD owns together

Some stocks are only available on invest. TSM for example

I hope Intel does well, nothing worse then having a monopoly and also competition is the best way to get innovation. Tho id argue Samsung is closer to TSM then Intel on Foundries
