$MRNA ripping ~150% in a day obviously looks insane, but I think the more interesting part is what the market is actually pricing in now.

This isn’t just traders saying one Moderna drug is worth more. The move looks more like the market suddenly assigning a much higher probability that Moderna’s mRNA technology can become a real oncology platform, rather than being remembered mainly as a Covid-era vaccine story.

That distinction matters.
A successful cancer program is valuable on its own. But if investors start believing the same underlying platform can be used across multiple tumour types, combinations and personalised treatments, you’re no longer valuing one drug. You’re valuing years of possible follow-on programs.

And that’s where these biotech moves get dangerous in both directions.
Before today, a lot of that future value was heavily discounted because clinical failure was still a huge possibility. One major positive result can suddenly move those probabilities, and because biotech valuations are basically probability-weighted future cash flows, the stock can move far more than you’d expect from near-term revenue alone.

Still, +150% in one session means a lot of future success just got pulled into today’s price. That would make me much more interested in the next data release than the candle itself.

I’d want to see:
actual size of the clinical benefit, whether results hold across patient subgroups, safety, manufacturing economics, how quickly personalised doses can be produced, pricing, and most importantly whether similar results start appearing in other cancers.

If those pieces line up, this could be bigger than melanoma and Moderna probably deserves a completely different valuation framework.

If they don’t, then today’s move may have simply priced five years of optimism into five hours. Also kind of wild looking at the S&P leaderboard now.
$SNDK +547% YTD
$MRNA +413%
$DELL +245%
$MU +217%
$STX +202%
$MRVL +171%

Most of the list screams AI infrastructure and memory.
Then Moderna just shows up in the middle of it.

Two completely different stories, but basically the same market behaviour: investors paying aggressively when they think a company’s long-term earnings ceiling has suddenly moved higher.

I wouldn’t chase $MRNA after a candle like this, but I definitely wouldn’t dismiss it as a meme move either.
The real question now is whether this was one great clinical result or the first proof that Moderna has a much larger oncology platform than the market thought yesterday.

What do you guys think? Genuine long-term rerating, or did the market get way too excited in one session?

Most traders don’t struggle because they have no rules. They struggle because the rules become negotiable once money is involved.

I have noticed this myself. Before entering a trade, my plan can look very clean. I know the level, the invalidation, and the risk. But once the trade starts moving against me, the mind starts bargaining. “Maybe I should give it more room.” “Maybe this is just noise.” “Maybe I entered a little early.”

That small negotiation is usually where discipline breaks.

For me, the hardest rule is not forcing trades after a missed move. Watching something run without me can make the next setup look better than it really is.

What’s one trading rule you keep breaking even though you know better?

Good morning everyone, before the market opens, I am trying to focus less on predictions and more on preparation.

One thing I have learned is that pre-market excitement can make almost every chart look better than it really is. A stock gaps up, people start talking about it, and suddenly it feels like you need to act quickly. But most of my better trades usually come when I already know the level I’m watching before the open.

Today I am keeping it simple: no chasing, no random entries, and no trade unless the setup still makes sense after the open.

Reddit becoming an S&P 500 company feels almost too ironic. $RDDT jumped more than 11% after S&P Dow Jones Indices confirmed it will replace AvalonBay Communities before trading opens on August 18.

The important part is the forced demand. JPMorgan estimates index-tracking funds may need to purchase around 16.7 million Reddit shares nearly three times its average daily trading volume since the IPO. That could keep volatility high around the index rebalance.

But index inclusion does not automatically improve the underlying business. Reddit still needs to prove that advertising growth, AI-data licensing and user engagement can offset unstable Google search traffic. The stock also remains well below its 2025 peak despite this rally.

For me, this is a strong short-term catalyst, but not automatically a long-term buy signal. Chasing after a double-digit jump can be risky once the forced buying is completed.

Would you buy $RDDT before the index inclusion,
or wait for the excitement to cool down?

This morning I analayed that the market is getting much more selective, and honestly today was a pretty good example.

$AMAT beat expectations and guided higher… stock still fell around 5%.

Meanwhile $RDDT jumped around 12% on S&P 500 inclusion and $SNDK gained 7%+.

So I don’t think the important question right now is simply “is the market bullish?”

It probably still is.

The better question is what expectations are already priced into each stock?

When expectations become too high, even really good results can disappoint the market. That was basically the main thesis in my pre-market note this morning, and today the tape confirmed it pretty well.

If anyone interested I can share the full article.

I think most traders are pulled between two fears.

The fear of losing money.
And the fear of missing the move.

Both can create bad decisions.

Fear of losing can make you exit winners too early, hesitate on good setups, or avoid trades that actually fit your plan. Fear of missing out can make you chase, enter late, ignore risk, or buy something just because everyone else is talking about it.

For me, FOMO is usually more dangerous. A missed move can make me feel like I need to “catch the next one,” and that is often where weaker trades appear.

The hard part is accepting that not every move belongs to you.

Which one affects you more: fear of losing money, or fear of missing the move?

And how do you manage it?

$CRWV was one of the wildest large AI trades today, up around 19% after earnings. (Reuters)

The headline story is simple: growth is exploding, but so is the cost to fund it.

Q2 revenue hit $2.58B, more than doubling YoY, while backlog surged to $104.2B with another $25B+ in new commitments this quarter. In other words, demand is clearly not the issue capacity is effectively sold out.

But that’s only half the picture.

The other half is capital intensity: CoreWeave raised 2026 capex guidance to $35–39B (from $31–35B) and spent $9.4B in Q2 alone.

So the setup is this:
Demand, backlog, and revenue are all accelerating sharply
But the infrastructure required to support that growth is scaling just as fast

That’s why I think CRWV is really a capital efficiency story disguised as a growth story.

The bull case is straightforward: if AI compute stays structurally scarce and CoreWeave continues locking in long-term contracts at strong economics, today’s massive capex could translate into years of contracted cash flow.

The bear case is more subtle: if GPU pricing, financing conditions, or AI demand shift before those investments pay back, the model gets stressed quickly.
So the key question isn’t just growth anymore.

It’s:
How much durable free cash flow can CoreWeave eventually generate for every dollar of infrastructure it deploys today?

If that improves, this becomes a very different business.
If it doesn’t, even a $104B backlog doesn’t guarantee attractive equity returns.
That’s what I’d focus on more than today’s +19%.

CoreWeave Q2 results

What do you think: is CRWV becoming the infrastructure winner of the AI boom, or is the market underestimating how capital-intensive this model really is?

Foxconn just gave another pretty strong signal that AI infrastructure demand is still not slowing down.

They said they still expect strong full year revenue growth and AI demand should remain one of the main drivers through 2026. Q2 profit was up around 35% to $1.86B and came above expectations.

For me the interesting part is Foxconn is one of the biggest manufacturers behind Nvidia AI servers. So when they are still seeing strong demand, it suggest the AI buildout is not only hype from big tech presentations. Companies are still actually ordering servers, GPUs, networking equipment and building data centres.

Foxconn is also expanding AI server manufacturing in Texas and Mexico, which tells me they are expecting this demand to stay for some time, not only few quarters.
Of course valuation is another question and many AI stocks already moved a lot. But from the demand side, I don’t see much evidence yet that the AI infrastructure cycle is slowing.

I would keep watching $NVDA, $SMCI, $DELL and $ANET.

Do you guys think AI infrastructure still has another 1–2 years of strong growth, or we are already close to peak spending?

Markets move on numbers, but they also move on stories.

That is something I find interesting. A stock does not always move just because earnings changed. It can move because investors start believing a new story about the future.

AI infrastructure is one example. Cybersecurity, energy demand, rates, small caps, and reshoring can all become narratives if enough investors start paying attention.

The tricky part is knowing whether a narrative is early, already priced in, or just hype.

For me, the best narratives are the ones that eventually show up in revenue, margins, guidance, or capex. If the story never reaches the numbers, it usually fades.

What market narrative do you think people are overlooking right now?

AI infrastructure, energy, cybersecurity, small caps, rates, or something completely different?

Options can punish small mistakes very quickly.

I think many beginners start options by focusing only on direction. They think, “If the stock goes up, my call should make money.” But then they learn about expiry, IV crush, spreads, liquidity, theta, and position sizing.

That lesson can be expensive.

For me, the biggest mistake is treating options like lottery tickets. Small position, big upside, fast money — it sounds attractive, but without a plan it usually becomes gambling.

The other big mistake is choosing expiry that is too short. Even when the idea is right, the contract may not give enough time for the trade to work.

Options are powerful, but they require more precision than normal stock trades.

What do you think is the biggest beginner mistake in options: bad timing, wrong expiry, ignoring IV, oversizing, or chasing cheap contracts?

The AI trade is much bigger than just one stock now.

That is what makes it interesting. Semiconductors get most of the attention, but AI infrastructure also touches cloud platforms, data centers, networking, power demand, cybersecurity, cooling, and software.

I’m trying to think about the AI market less as a single stock story and more as an infrastructure cycle.

The hard part is figuring out who actually benefits first. Some companies fund the buildout. Some supply the hardware. Some provide software. Some may benefit later, but not yet in earnings.

That distinction matters for investors.

For me, the question is: where is real demand already showing up, not just where the narrative sounds good?

Which part of AI infrastructure looks most interesting to you right now: chips, data centers, cloud, cybersecurity, or energy demand?

Having a stop loss and actually obeying it are two different things.

I learned that the hard way. Before entering, the stop always looks logical. It feels like part of the plan. But when price gets close to it, emotions start making arguments.

“Maybe I placed it too tight.”
“Maybe it’s just a shakeout.”
“Maybe I should wait for confirmation.”

Sometimes that might be true, but often it is just discomfort talking.

For me, moving a stop after entry is usually a warning sign. It means I’m no longer following the original plan. I’m trying to avoid the pain of being wrong.

A small planned loss is manageable. A moved stop can become something much worse.

Do you usually respect your stop loss, or do you sometimes negotiate with it?

Before looking for upside, I am trying to ask what could ruin the setup.

That one question has saved me from a few bad trades. Sometimes a chart looks good, but the broader market is weak. Sometimes a stock has momentum, but volume is thin. Sometimes the setup is clean, but there is a major catalyst coming that can completely change the trade.

I used to focus mostly on the opportunity. Now I try to identify the risk first.

It does not mean avoiding every trade. It just means knowing what would make the trade invalid.

For today, I’m watching for weak breadth, overextended tech, news risk, and whether momentum actually follows through after the open.

What could ruin today’s setup in your view?

Yields, oil, earnings, volatility, weak breadth, or something else?

Before the week starts, I am trying to think less about what I want the market to do and more about what could go wrong.

That has helped me avoid forcing trades. If I know the main risk in advance, I’m less surprised when price moves against the obvious narrative.

This week, the risk could be anything: yields, oil, inflation, earnings, AI stock weakness, small-cap pressure, geopolitical headlines, or just overextended price action.

For me, the useful question is: what would change my view?

If I can answer that before the week starts, I usually make better decisions when the market opens.

What is the one risk you are watching this week?

And what signal would tell you that risk is becoming serious?

One idea from Trading in the Zone that still sticks with me is that a good trade is not always a winning trade.

That sounds simple, but emotionally it is hard to accept. I’ve had trades where I followed my plan and still lost. I’ve also had trades where I broke my rules and still made money.

The dangerous part is that the market can reward bad behaviour in the short term. That makes it easy to confuse profit with skill.

For me, the lesson is to review trades based on process first, outcome second. Did I follow the setup? Did I manage risk properly? Did I respect the exit?

If the answer is yes, the trade may still be good even if it lost.

Have you read Trading in the Zone?

What lesson stayed with you most?

I think a lot of confusion comes from not knowing what game we are actually playing.

Sometimes people say they are investing, but they panic over every daily move. Others say they are trading, but when the trade goes red, it suddenly becomes a “long-term hold.” I’ve definitely caught myself blurring those lines before.

Trading needs risk levels and invalidation. Investing needs a thesis and patience. Reacting has neither.

That distinction matters because the wrong mindset creates bad decisions.

If I enter as a trader, I should not pretend to be an investor just because the trade moved against me. If I invest long term, I should not panic because of one red day.

Be honest: are you mostly trading with a system, investing with a thesis, or reacting to price movement right now?
