$Lumentum(LITE.US)

Lite experienced an extreme rollercoaster ride. With the merger and acquisition finally settled, it caught the market fear moment and has already broken below 700.

My move: I added to my position with a view to averaging down.

Taking away: In volatile markets, active trading is needed; the 'buy and hold' strategy is no longer effective.

$AMD(AMD.US)

Context: AMD has plummeted so much that it feels numb. No matter the earnings results tonight, I won't be able to break even.

My strategy: Lie flat and hold. I basically plan to hold through the New Year.

Summary: I still have confidence in this AMD position, but I have to admit my trading strategy is flawed. Risk management was inadequate. Failing to cut losses or being hesitant to do so leads to unlimited downside. The speculative game turns into a test of endurance, causing one to forget the original thesis and reason for buying. It's all about emotions; as Xiao He makes him succeed, so does he make him fail.

$VanEck Gold Miners ETF(GDX.US)

Background: Gold also experienced a significant downturn this week, hitting a low of 82.4. My mindset for holding gold is for safe defense; I continue to hold despite the drop.

My actions: No position increase or decrease. Stay calm.

Insights: Gold has strong support around 4100. Gold should be allocated no more than 10%; exceeding this is not a safe allocation and makes it hard to maintain a stable mindset, as volatility is considerable.

$Micron Tech(MU.US)

Background: CPI came in higher than expected, intensifying bearish sentiment. The probability of an October rate hike has risen. In reality, the 10-year U.S. Treasury yield is trending downward, and market sentiment has clearly cooled.

My Strategy: Continuing to execute a tiered buying strategy to average down the cost basis, waiting for the market to recover.

Insights: Market volatility is increasing. I remain confident in Q3 earnings momentum, strong corporate profitability, and the unchanging trend of AI transformation. Discipline leads to freedom.

$NVIDIA(NVDA.US) Is it too early to open a position at the $240 high? My basic judgment of the current market is that volatility will intensify, so I am adopting active trading rather than passive holding. This is my Nth time building a position in this stock; I also bought when NVIDIA dropped to $220, keeping my current cost basis at $230. I have no regrets and remain committed to my strategy.

Of course, this approach would be ineffective in a bear market, but I believe the AI-driven rally led by the US is the best option with no alternative.

So I hold bravely.

If I were to share one lesson learned, I'd say: In volatile markets, always keep cash ready. Don't go all-in at once.

$Micron Tech(MU.US)

The fear sentiment in the AI sector is starting to spread. It has to be said that hot money and institutions are quite cunning. During the most terrifying period of US Treasuries, they didn't sell off; instead, they baited longs before fleeing.

However, I will continue to hold quietly, planning to add positions on 9/20 to average down, as I can hold for the long term.

The lesson is that the sector allocation shouldn't be too concentrated, otherwise it's easy to lose one's composure.

$Taiwan Semiconductor(TSM.US)

I've been watching TSM since it broke below 375 in July. I've traded the volatility, buying and selling multiple times. The previous rally was too fast, and I failed to hold. After the recent US debt crisis pushed prices back down to 450, I've re-entered.

My thesis is that US Treasury yields won't drop anytime soon. I'm treating the panic as noise; the bearish sentiment ahead of the midterm elections has already been priced in. Plus, AI remains the only cure.

Now, we'll just have to wait and see how the market plays out.

For high-quality names like TSM, you shouldn't sell everything due to market volatility. It's better to keep a core position.

$VanEck Gold Miners ETF(GDX.US)

Gold dipped at the start of the week amid a US Treasury bond panic before stabilizing.

I decisively bought into GDX, treating it as a gold futures proxy with 1.5-2x leverage. Not that it actually has leverage, but its volatility is 1.5-2x higher in performance.

I tend to favor it over pure commodities when trends are clear.

Of course, I also buy it in combination with others, using them as detectors for market sentiment.

$United States Oil Fund LP(USO.US)

In the current backdrop of soaring US Treasury yields, fewer stocks can generate profits. Margins are being compressed, forcing reliance on price hikes as a driver, which comes with massive volatility. Simply holding is hardly a good strategy; the era of easy 'lying flat' wins is long gone.

After looking at it from all angles, I still think short-term trading of oil ETFs is the way to go.

What do you think?

$Reddit(RDDT.US)

Although it was a poor entry, I remain relatively confident.

I believe Reddit has a unique moat in the AI era. The internet is currently flooded with generative data, while Reddit's community mechanism preserves it as a repository for genuine human activity and information.

Selling data to model companies looks like a promising business model going forward.

Holding.

This stock is highly volatile, making entry and exit points difficult to time. Do you have any tips? I'd appreciate your advice 🙏

$Reddit(RDDT.US)

Reddit lived up to expectations, rising against the trend yesterday, although the entry price wasn't ideal.

The rationale for buying: Reddit's authentic community rules make it a sanctuary for genuine emotional exchange in the AI era and a valuable resource for AI training.

I bought at 155 and am holding firm.

Reflection: This asset is highly volatile, comparable to small-cap AI concept stocks; swing trading might be more effective.

$Keppel DC Reit(AJBU.SG)

Keppel Data Centre announced a rights issue today, with the size accounting for over 10% of total share capital. The stock price has dropped significantly amid panic.

I'm not particularly worried and haven't reduced my position; instead, I'm considering adding to it, though still weighing in on the price.

The main reason is that I believe this is an equity-dilutive offering, likely for acquiring the Tokyo data center. My only concern is whether this week's CPI data will add to the pressure on rate hike expectations.

$Reddit(RDDT.US)

Context: Seeing AI giants devour Reddit’s data as premium ” digital dog food“, combined with its shiny S&P 500 badge, I refused to believe joining the big league meant instant doom.

My trade: Opened a position in Reddit around $155. I got instantly trapped and felt the icy winds at the peak, but I‘m holding long-term. For a high-volatility software stock sitting on an AI data goldmine, this dip is just a temporary detour.

Takeaway: Next time, hold my horses and wait for an entry near the cozy $140 consolidation pad.

$Keppel DC Reit(AJBU.SG)

Context

Keppel DC REIT took a massive hit today, continually testing new intraday lows.

Action

I already averaged down yesterday at $2.20, but with it dipping further to $2.19 today, I lost my nerve. I‘m officially putting my buying on hold.

Why

The broader Singapore market is pulling back from its highs, and almost all the heavyweight stocks are flashing daily MACD bearish divergences. Right now, it feels like catching a falling knife—waiting it out is the only sensible move.
