Been thinking about what the AI software stack could look like over the next few years

Layer 0: Foundation Models | OpenAI, Anthropic, xAI
- The reasoning engine powering everything else

Layer 1: Product Intelligence | $AMPL
- Continuously identifies user friction and what the product should improve next

Layer 2: Autonomous Engineering | Prime Intellect, Codex, Cursor
- AI agents that write code, fix bugs, run tests, deploy, and improve their own workflows

Layer 3: Enterprise Knowledge | $BOX - Gives AI the business context it needs i.e. requirements, documentation, policies, compliance, design standards, and more

Layer 4: Data Management & Orchestration | $SNOW, Confluent
- Connects enterprise systems and gets the right data to the right AI, at the right time, with the right permissions and freshness

Layer 5: Observability | $DT, $DDOG
- Answers “Did anything break?” Monitors logs, APIs, latency, infrastructure, and automatically surfaces root causes

Layer 6: Experimentation | Statsig
- Safely rolls changes out to a small % of users before deploying broadly

Layer 7: Security | $PANW, $CRWD
- Validates vulnerabilities, permissions, secrets, identities, and compliance before and after deployment

If this becomes a standard for software, the next wave of AI winners may not just be the model providers… but the companies that own one of these critical layers

@TheRonnieVShow There’s a lot of people that are married to their positions. They’ll turn any negative news into a positive. You described it well though, lots of marketing on this platform

@WOLF_Financial Have an 9hr flight next week, was going to download 10 earnings reports and try to listen to them the entire flight 😂

[Zeff @zeffpena]

Hardware and software names have traded like the 30-year treasury is above 5% (currently at 5.2%) $SMH $IGV

While the broader market is still sitting near at all-time highs…

$DUOT is up nearly 60% since this post 3 months ago

Duos Technologies has signed 5-year hosting agreements with Axe Compute covering 55 MW and more than $500M in contractual base payments

The story has continues to develop

Stock is currently trading above all moving averages

[Zeff @zeffpena]

SMID Spotlight: $DUOT Duos Technologies

No position currently, but this is one of the more interesting small-cap pivots I’ve seen recently

Historically a rail + consulting company, now aggressively pivoting toward Edge Data Centers (EDCs) tied to AI infrastructure

Management is actively winding down lower-margin legacy business while pushing into higher-margin edge compute infrastructure

Recent earnings showed:
- improving backlog
- expanding EDC pipeline
- stronger AI/data center positioning

They guided for $50M revenue in H2–good execution will lead to a rerate on the stock; however, can they get there while keeping CapEx low

But if the pivot works, the market may eventually stop valuing $DUOT like a rail company and start valuing it like an edge AI infrastructure play

One of the strangest markets I’ve experienced

Recent earnings were strong, AI infra is being built at historic scale, and we’re arguably on the cusp of major breakthroughs in AI, automation and robotics

Yet geopolitical tensions persist, bond yields are pushing multi-decade highs, Asian markets are flashing stress, and fiscal pressure keeps building globally

There is so much to be bullish about underneath the surface, yet the macro backdrop feels like it's hanging on by a thread

🚨 South Korea just triggered a sell-side “sidecar” on the KOSPI, pausing program sell orders for 5 minutes after KOSPI 200 futures fell +5%

Meanwhile, the yen is sliding back toward 160 while Japanese bond yields push to multi-decade highs

Asian market stress continues

[Zeff @zeffpena]

@Sam_Badawi At least the Shanghai markets aren't as bad as the NIKKEI and the KOSPI. We'll see how robotics names react tomorrow after IPO $TER $ON $NXP

$NBIS update:

The Vineland Planning Board just approved DataOne/Nebius' amended site plan in a 9-1 vote

This allows the Vineland buildout to continue

Important de-risking event for the 300 MW campus and the capacity tied to the $MSFT contract

[Zeff @zeffpena]

Quick context on the $NBIS Vineland hearing later today:

This isn't a vote on banning data centers

DataOne/Nebius already has approval for the site and construction is underway. The hearing is for amendments to the site plan, including the on-site power infrastructure

This matters because Vineland capacity is tied to the $MSF contract. Nebius needs to bring that capacity online before the associated revenue can ramp

Could slightly impact the timing of the capacity and revenue ramp

$NFLX Netflix | Daily | 6M

Netflix has traded below its major moving averages for much of its drawdown since April

Momentum has been shifting since the start of August with ~$81 being the next key level to reclaim the weekly 21 EMA and continue it's path upwards

$FLNC Fluence Energy | Weekly | 1Y

$FLNC is trading below every major moving average across the daily, weekly and monthly charts

The first sign of improvement would be price reclaiming those shorter-term averages

A good example of a chart I avoid. Need to see recaptures first

[Zeff @zeffpena]

@skkxvkgkodcl12 $36.30 for $FPS

[Zeff @zeffpena]

Up to over 35%% cash now

Holding just a handful of high-conviction plays:
$AMKR
$NBIS
$PLTR
$NVDA
$OSS
$AMPG
$FPS

Recently bought into $TE LEAPS (former Leopold name) after the strong $FSLR beat

[Zeff @zeffpena]

@HirschVentures @LilyFunds Still holding $5 Jan 28’ $TE calls

They are up 30% since the initial buy. I believe the upcoming midterms will be a positive catalyst for solar stocks

[Zeff @zeffpena]

Exited $AMPG for nearly a 50% gain after a couple-month hold

Still like the long-term potential, but I’m exiting for now. Open to revisiting $AMPG as execution improves

A few recent starter positions: $BSY $WLDN $BOX $LDOS

[Zeff @zeffpena]

@_TheStockCube @WOLF_Financial I’ve spotted myself, haha. Those stock cubes are awesome, they look great in person

[Zeff @zeffpena]

@fundmyfund Perfect thanks, will definitely check it out

[Zeff @zeffpena]

@LilyFunds I do not, what a great chart though. 18% day right as the 9EMA crosses the 50/100MA

Added $LPTH to my research list for this weekend
