The first concentrated investment in PLTR was made in 2025, and this week profit-taking was gradually advanced and diversified into other stocks. As of February 14, 2025, the year-to-date profit and loss is about +17%, but over 80% of the position in PLTR was sold for profit, reducing the investment amount to a level that allows for acceptable risk in the medium term.
As topics for personal investment selection, the CPI was higher than market expectations, and with easing expectations, 3% was placed in C, and combined 8% in healthcare-related AI stocks GEHC, TEM, and AIFF. Following the announcement of AI functionality in partnership with AAPL, BABA was incorporated into the portfolio, reaching nearly 4%. Particularly for BABA, since it is the first investment in a Chinese company in a lifetime, it is being closely monitored.
But from this afternoon, there will be a break from investing for another 96 hours because I will be playing Monster Hunter. I'll play until I defeat Arshubeld with 14 Weapons!

This week, positions in NFLX, CEG, OKLO, WMT, EAT, BK, TEM, RDDT, AEM, HOOD, CLS, TWLO were closed, focusing investments on PLTR. As of February 7, 2025, the year-to-date profit and loss is around +13%.
Since concentrating investments in one stock is considered high risk in the medium to long term, plans for gradually realizing profits are in place. However, as Monster Hunter's OBT2 is starting now, investments will be left aside for the time being, and there is no plan on which stock to invest in.
Wishing everyone a great weekend!

Since there was a request for a post about CUDA last time, I will write about what I know about CUDA, peripheral knowledge and insights, considerations for investment based on that, and current positions.
Many companies choose NVDA's GPU for AI development even if the product price is high, and the background of using CUDA is the technical advantage and the completeness of the ecosystem of the company.Technical AdvantageandComprehensive EcosystemThere is. I will list the reasons and specific examples below.
$NVIDIA (NVDA.US)$
1. Technical superiority of NVDA and its applications
1-1. Optimized parallel computing with CUDA.
CUDA is NVDA's proprietary platform for efficiently harnessing GPU parallel computing. Many AI frameworks (e.g. TensorFlow, PyTorch) utilize CUDA for optimization, leading to significant performance differences.
Specific Examples
自然言語処理（NLP）: ChatGPTのような大規模モデルのトレーニングや推論は非常に計算負荷が高いが、CUDAに対応したNVDAのGPUを利用することで、高速な処理が可能になる。

Last week, the decline and recovery of US stocks by DeepSeek significantly affected the entire market. However, the full picture seems to be still in the midst of confusion and chaos regarding development methods, equipment and costs involved, performance, as well as arbitrary responses. Since the last time I wrote about CUDA, I extended it to investment actions based on its position in the AI ecosystem. This time, I will write about what I know, what I think, and my current investment actions as the key points of DeepSeek becoming a hot topic.
What I am particularly interested in due to the widespread recognition of DeepSeek this time are two techniques that DeepSeek uses for AI model development: 'Distillation' and 'PTX'.
First, in AI model development, 'Distillation' refers to the technique of transferring knowledge from a large model (teacher model) to a smaller model (student model). This is generally used to maintain performance close to the original model while reducing computational costs.
Mechanism of Distillation
1. Training of Teacher Model

Although it seemed like it might recover yesterday after starting with DeepImpact last week, when I woke up this morning, the index closed in negative territory, confirming that it was indeed a challenging market.![]()
The index is clearly in a range. The range market that started from the sharp drop on December 17th may still continue.![]()
Yesterday, Japanese stocks, $Remixpoint (3825.JP)$ reached the high of 2022, so I took partial profits there.
In the USA market as well, $Celestica (CLS.US)$ Despite it being the day after the earnings announcement, the stock is rising significantly, so I thought it was a chance and entered a little. Since I was hit by soaring stocks in January, I have a small position. It was good that it was updating the highs until halfway through... but towards the close, it had a long upper shadow.![]()
The volatility is high, and there seems to be a possibility of a decline next week, so I sold in the Post-Market Trading.![]()
Looking back at January,
Now, January has become a month where I have to reflect deeply.![]()
Even though I made a comeback towards the end, being temporarily down 10% is too much of a loss.![]()
The person who won in January is really amazing, isn't it?![]()
If you are also a long-term investor, January is probably positive, so long-term may be more advantageous than short-term...

There is not a single creature in the natural world that eats before going out to hunt
Until obtaining prey from morning, one has no choice but to be active on an empty stomach
I definitely want to ask such a question
The key to health is "breakfast"... It is recommended to intake 20-30% of total daily calories (Daily Gendai Digital) - Yahoo! News.

First of all, as of January 28, 2025, the year-to-date profit and loss is around 1% positive, but the impact of DeepSeek on US AI and data center related stocks on January 27 was significant. Investments in AI and data center related stocks from 2024, such as NVDA, were liquidated for the time being.
Although semiconductor stocks such as NVDA, AVGO, ARM had significant unrealized gains at the end of 2024, profits were gradually taken to invest in other stocks. By the end of January 4th week, positions were significantly reduced. However, after the information about DeepSeek became widely known on the 27th, the related stocks all fell, confirming the liquidation of all positions. Additionally, around 80% of Energy stocks with high expectations for data center demand, such as CEG and VST, were profitably closed for similar reasons. It is believed that in the very short term, there is a possibility of buying back any stock, but if H800 can achieve performance equal to or surpassing OpenAI, Anthropic, and Google's generative AI, the story of the significant increase in demand for the latest powerful GPUs and ASICs, as well as electrical requirements, may be reconsidered, and the cost-effectiveness of these investments may become clearer in the near future. Considering that it is open source, there may be a need to revise the investment selection policy based on its capabilities, demand, country risks, etc., and I would like to conduct sufficient information collection, analysis, and stock selection. There is also a possibility that the positioning of META's Llama will change further, and TEM is held since the beginning of 2025, although recent profits have been taken for TSLA and VRT, the interest in AI related stocks remains.

I have decided to take a break this week, so I will not go shopping, but if I were to rebuild my portfolio, I would consider these stocks.![]()
Yesterday's decline seems like a temporary pullback, and the uptrend is likely not broken. $Palantir (PLTR.US)$ 、 $Robinhood (HOOD.US)$
After bouncing on good financial results, it is showing further signs of upward movement. $Twilio (TWLO.US)$
It may be a modest rise, but it is a stable stock. $Brinker International (EAT.US)$
I pushed back in the second half of the day, but the high was updated again. $Walmart (WMT.US)$
I bounced in the Stargate plan, but I didn't particularly decrease in DeepSeek. $Tempus AI (TEM.US)$
However, this month the market sense is completely off, so even if you buy, you might lose.![]()

Last night before going to bed, my portfolio was in a nice positive range, but when I woke up in the morning, the gains had disappeared, which was a bit disappointing.![]()
Since it's Friday, it seems like a time to take profits, but there's no helping it.![]()
Regarding my portfolio, I've solidified it with three U.S. stocks.
The strategy is to hold yen and dollars in equal measure, but I no longer had max positions for dollars. $Brinker International (EAT.US)$ Sold. This stock is experiencing stable growth and is really good, but in terms of yield, it is modest.
With Trump's inauguration, the market is on an upward trend, and it should be determined to take more risks, so sold EAT. $Robinhood (HOOD.US)$ Increased the Buy. $Robinhood (HOOD.US)$ 、 $Celestica (CLS.US)$ 、 $Palantir (PLTR.US)$ The three have become more than half of the portfolio.
In addition to these three, there is a slight position in US stocks. $Tempus AI (TEM.US)$ I plan to solidify my position in US stocks for now and won't make any changes unless something unusual happens with these stocks. $Celestica (CLS.US)$ The earnings report...
