Physical AI will come in many forms — robots, humanoids, drones, autonomous vehicles, and more!
But before you get into any of that, you need to understand that physical AI is a many layered cake:
Layer 1: Semiconductor & Embedded Systems
Layer 2: Sensors & Perception
Layer 3: Edge Systems & Embedded Infrastructure
Layer 4: Simulation, World Models & Robot Training
Layer 5: Robotics, Autonomy & Machine Control
Layer 6: End-Market Integrators & OEMs
Layer 7: Power, Connectivity & Distributed Infrastructure
Layer 8: Proprietary Physical-World Data Loops
Over the next few weeks I'm going to dive deep into each layer, starting with semis.

But I’m not trying to own every semiconductor company, I want to find asymmetrical opportunities within each layer. A few of the questions I’m asking before investing in this theme are:
> Is this company a true bottleneck?
> What physical-world problem is it solving?
> How differentiated is it versus competitors?
> Is the moat wide enough? Does this company get designed into long-life systems like cars, robots, factories, industrial equipment, medical devices, or infrastructure?
> Is the valuation already pricing in the opportunity?

In the next few days, I'm going to break down which names I'm excited about in this layer and why.

No new trades today, even though there were some monster setups.
I watched $MSTR, $OUST, $AMKR, and $INTC, but this week was exhausting. I had enough energy to manage existing trades, not force new ones.
A big part of trading is knowing when to push and when to sit on your hands. The broader market felt selective despite strong semi strength, and I’d rather wait for cleaner setups next week than chase when I’m tired.
There will always be another setup.
$VELO faded, so I took half off.
$ARM was the cleanest one. Strong marubozu yesterday, then a perfect continuation off the 9 EMA today. Pleased with how this played out and my entry yesterday.
$GLXY faded midday, but stayed above key EMAs. I still have cushion in the trade and more than a month left on the option, so I held.
Today felt quieter than expected outside of the SpaceX IPO, which was obviously the main market event. Iconic in so many ways: Largest IPO ever, thousands of new millionaires, and one for the history books!
Might post a few charts this weekend, plus a deep dive into my first physical AI stock pick.
Have a great weekend all.

What a day!
$SPY and $QQQ looked like they wanted higher early, then started fading about an hour into the session as headline risk pressured the market. Mostly stayed patient to watch whether the dip would get bought or turn into a real breakdown like the past few days did.
The exception to this was $VELO.
While the indices were starting to fade, $VELO kept showing clear RS. It was already trending on the daily chart, had a strong catalyst with the SpaceX IPO, and refused to fade with the market. That was the signal for me. I took the trade, and it ended up having a monster day, closing up ~35% on insane volume.
$VELO has also had some fundamental catalysts that are driving the re-rating, like the Aurelia partnership, DoD contracts, and more. @kingtutcap has the most in-depth DD on this in case you want to follow along! Names that have strong fundamentals backing them end up making the biggest moves!

I’ve been posting a lot of my technical trades here, but I’ve also been learning fundamental analysis in the background.
One theme I’m increasingly interested in is physical AI — robotics, sensors, edge compute, semis, power, automation, defense, mobility, and industrial systems.
I’m going to make this a series and share the stocks, research, and rabbit holes I find along the way.
Not investment advice, just learning in public.

Tiny experiment from today:
On days like today, 2x leveraged ETFs feel like such a hack for catching an extra move.
I added some $ARMG and $SNDU this morning instead of adding common shares of $ARM and $SNDK. When the underlying names are moving 10% in a day, the 2x products can multiply pretty quickly!
Definitely not something to treat as a long-term investing vehicle. The daily reset can cut both ways, especially in choppy tape.
But on strong trend days, with a clean setup and tight risk management, they can be a pretty useful tool without having to worry about options or time decay.
What wild times to invest in!
NFA do your own DD!

Later in the day, $SPY and $QQQ printed a high-volume reversal, with buyers stepping in aggressively near the daily 50 EMA and weekly 9 EMA spot for $SPY.
War resolution news, combined with the fact that $SPY was in a do-or-die spot, meant buyers stepped in aggressively. I waited for about an hour after reversal but it looked like the market wanted higher, so I dipped my toes into half-sized calls on $GLXY and $ARM.
$GLXY broke through a clean daily resistance zone on volume and had been showing RS on my screeners for the past few days. Strong lift-off from the 9 EMA into a 10% day.
$ARM reclaimed short-term strength intraday, though it is more extended and probably needs tighter risk management. I have been following ARM for a while now, and it’s a chart I know well. I’m trading it not just for RS, but also because it’s something I understand well. $ARM made a strong bullish candle that sliced through the 21 and 9 EMAs, so I’m playing this as a continuation trade rather than a base breakout.
Charting is so much about pattern recognition and repeatability, and I’m trying to use that to my advantage despite missing so many other incredible setups today. Sitting with some cushion on both trades.
Some of the setups I missed: $ASTS, $LUNR, $MU, $SNDK, $INTC, $LRCX, $HOOD.
But I’m actually okay with that. The goal was not to buy everything moving. The goal was to stay selective and avoid getting too leveraged too quickly in case we reverse tomorrow.
Still not fully out of the woods. $SPY hasn’t fully reclaimed all the key short-term moving averages yet, so I’m staying patient and treating these as trades that need to keep proving themselves.

Reminder: If you don’t panic buy all the stocks you sold last week right now, someone else will beat you to it

Welp, that’s 4 straight days of SPY and QQQ selling into the 50 EMA. Tape is getting heavier.
Best move here is to sit on your hands and avoid overtrading. No new longs, no new trades today. Not buying random dips anymore and risking capital.
WHEN you buy matters more than what you buy.
$SPY really needs to defend this zone, with the daily 50 EMA and weekly 9 EMA converging here.
Lose this area and the tape likely gets uglier, with more downside pain ahead.

Physical AI tickers have shown so much relative strength through this drawdown, most of them haven’t even touched their 21 EMAs! Signs that it continues to be the theme to watch!

Today was a great day to study the charts.
$SPY and $QQQ both bounced at textbook spots, with weekly 9 EMA support lining up near their daily 50 EMA areas.
Higher timeframes are becoming my go-to for understanding overall market structure. And when multiple timeframes stack around the same level, I’m learning to pay attention.
The intraday tape felt chaotic, but zooming out made the picture clearer. The market showed where buyers needed to defend, and they did.
The more levels that converge in one area, the more important that support zone becomes.
Still not assuming we’re fully out of the woods, but today was a good reminder:
When in doubt, zoom out.

Once I got confirmation of a reversal, I took a shot at adding to a couple of my longer-term, higher-conviction longs.
Is the market going to dip further? I don’t know. Nobody does.
But when multiple timeframe levels converge and buyers show up where they’re supposed to, that’s often the kind of area where I’m interested in adding exposure selectively.
For now, I’m staying away from forcing short-term entries, but I’m happy with my dip adds in $FIVN and $ADEA .
Still cautious about opening shorter-dated options. CPI tomorrow, and the tape can change fast.
