It feels like the next two years will still be a super cycle for storage. Even the largest company by market value in China is Changxin, a company that was only established 10 years ago. On the US stock trading leaderboard, Micron and SanDisk dominate every day. The entire market is still very short on storage, and scarcity makes it valuable, so there’s still room to play in storage. Although everyone is building factories and expanding production, it’s hard to ease the shortage within two to three years. Even after construction, it will take another two to three years to start production. Many orders are already scheduled as far out as 2030 or beyond.

Learn to roll positions, even small capital has the chance to reach millions The core of rolling positions is not high leverage, but using profits to expand profits under the premise of a correct trend. True rolling positions first require protecting the principal, controlling leverage, and exchanging time for space, rather than fantasizing about getting rich overnight. What is rolling positions? Many people feel "rolling positions" is risky. In fact, rolling positions is another way of saying adding to floating profits. When your position has already generated considerable floating profits, and the trend is confirmed to continue, you use the profits earned to moderately increase your position, allowing profits to continue to expand with the trend. It is just a capital management method in trend trading, not a way to predict the market. Why can't many people roll positions? Because most traders share a common problem: They can't hold onto profits. They are eager to realize profits as soon as they make a little, fearing profit retracement. The result is: They hold losses for a long time but hold profits for a short time. Over the long term, even a high win rate struggles to accumulate large gains. True big moves usually only occur during a very small portion of the year, and most profits often come from just a few trades. What kind of market is rolling positions suitable for? Rolling positions is only suitable for clear trending markets, not ranging markets. For example: Volume breakout after long-term bottom consolidation; Important breakouts on daily or weekly charts; The end of a pullback after the first bull market rally, followed by a restart. No trend, no rolling positions. How to operate rolling positions? Rolling positions is not about continuously chasing highs. There are usually several common methods: First: Add positions on breakouts During a trend, after a high-level consolidation completes and volume breaks out again, you can moderately increase your position. Adding positions after a breakout is trend-following, not chasing a rally. Second: Add positions on pullbacks During an uptrend, after a normal pullback stabilizes near moving averages, trendlines, or key supports, gradually increase your position. This method usually has a better risk-reward ratio. Third: Roll profits into profits As account profits increase, the actual leverage of the original position decreases. If the trend logic remains unchanged, you can use the profits already gained to restore the original risk exposure, rather than betting heavily from the start. Leverage is not better the higher it is Many people misunderstand rolling positions as continuously increasing leverage. In fact, experienced traders prefer to use relatively low leverage, such as 3 to 5 times. Low leverage means: Able to withstand normal fluctuations; Less likely to be stopped out; Enough time to wait for the trend to play out. The real profit comes from the trend, not leverage. The biggest risk of rolling positions The biggest risk of rolling positions is not adding positions, but persisting in adding positions in the wrong market. Only consider rolling positions when two conditions are met: The trend judgment still holds; There is enough floating profit as a safety cushion. Once the trend is broken, you should execute stop loss, not keep adding positions to lower the cost. The most important sentence Rolling positions is not a get-rich-quick secret, but a capital management technique. It won't turn wrong trades into right trades, only make right trades earn more. Therefore, rolling positions is always based on three premises: Correct trend, controllable position size, and disciplined execution. Additionally, the funds used for rolling positions should be risk capital you can afford to lose, not borrowed funds or money that affects your normal life. Only then can you truly hold the trend and wait for profits to grow.

Always remember, you are a speculative trader. Speculation is about making money by following trends. Whether it's Crypto or US stocks, only do trend trading, don't predict, just follow, and go with the flow.

After last month's big drop until now SanDisk rebound: 63% Micron rebound: 27% Hynix rebound: 30%

Aggressiveness: SNDK > SKHY > MU Fundamental Certainty: SKHY ≈ MU > SNDK Valuation Cost-Effectiveness: MU > SKHY > SNDK Elasticity: SNDK > SKHY > MU

The long positions I opened on $SKHY and $SNDK a few days ago were both closed during the day today. Although I made some profit, I missed out on tonight's big surge, which is really a pity and shows I didn't do well. Tonight, when the US stock market opened, I chased $MU but didn't go for $SNDK, which was also a mistake. I clearly knew that $SNDK has greater volatility and generally larger gains.

SanDisk good news: SNDK expects a gross margin of about 80% for fiscal years 2028 to 2030, achieving mid-to-high double-digit revenue growth, and will return 100% of excess cash to shareholders.

MU looks at the storage super cycle, AMD focuses on the AI computing power cycle, MRVL targets AI networking, SNDK emphasizes extreme NAND flexibility, SK Hynix leads in HBM, and INTC watches for a turnaround in U.S. manufacturing and challenges.

First Tier: Core Positions MU + AMD These two have the clearest logic. MU = AI Memory AMD = AI Compute One is the storage cycle, the other is the computing power cycle. ⸻ Second Tier: Offensive Positions SNDK + MRVL These two are suitable for swing trading. Especially SNDK: It surges the most when rising and falls the hardest when dropping. So it's not suitable for holding long-term, but better for: Breakout → Add positions → Accelerate → Reduce positions Rather than staying fully invested all the way. ⸻ Third Tier: Watchlist Positions SK Hynix + INTC I am actually very optimistic about SK Hynix's fundamentals, but currently it seems more like waiting for technical confirmation. INTC belongs to a different playstyle: Betting on successful transformation.

Storage is king, the market hotspot is still storage, focus on the three major leaders $MU $SKHY $SNDK, and add more long positions again.

Absurd and ironic phenomena in the human world: 1. Men and women who have achieved nothing become great parents after just one night of sleep. 2. Ancestors who lived a lifetime in poverty are expected by their descendants to bless them with wealth. 3. Seeking romantic fate in celibate temples, asking monks who never leave the monastery about life. ​​​ 1️⃣ Reproduction only requires physiological impulse, with no threshold, assessment, or mental maturity needed. Many people themselves are still confused and incapable of managing life, yet they naturally hold the identity of "parents," forced to bear the responsibility of raising children. Others automatically bestow upon them the great label, ignoring their own confusion and mediocrity—this is the most common human paradox. 2️⃣ Ancestors lived a life of hardship and poverty, never escaping suffering, yet after death, their descendants place hopes on them to bring financial fortune. People are unwilling to rely on their own hard work and instead pin their hopes on the spirits who never possessed wealth, avoiding their own efforts and entrusting desires to the void—full of irony. 3️⃣ The core of Buddhism is to sever worldly love and attachments, yet temples are crowded with people seeking romance and good matches; monks live secluded in the mountains, isolated from worldly affairs and workplace conflicts, yet worldly beings persistently ask these detached monks to solve secular problems, seeking answers externally and refusing to introspect.
