A 2-year and 9-month record of buying both US tech stocks and Indian stocks with the new NISA.
Two years and nine months have passed since the start of the new NISA.
I have been steadily accumulating investments every month,
and here are the results as of the end of September 2026,
including the multiple investment trusts I have purchased in the growth investment quota.
My investment strategy is as follows:
in the installment investment quota, starting from January 2024, I have been investing 100,000 yen per month into the S&P 500,
and in the growth investment quota, I have purchased 400,000 yen of US semiconductor stock funds (SOX), 1 million yen of NASDAQ 100, and 1 million yen of India’s Nifty 50
.
I have continued to invest with the same strategy in 2025 and 2026.
As of the end of September 2026, the total investment amount is 10.5 million yen.
Performance by ticker
S&P 500 in the installment quota is up 32.4%
First, let’s look at the Rakuten S&P 500,
which I have been investing in at 100,000 yen per month in the installment investment quota.
Against a total investment of 3.3 million yen,
the unrealized gain updated on September 30th is 1.07 million yen,
a gain of +32.4%.
The orange line on the graph represents the net asset value.
Although it has been moving mostly sideways since June of this year,
the total return since January 2024 is up 32%,
so it can be said that it has been performing quite well so far.
Semiconductor stock SOX is up 129%, more than double the investment amount
Next are the investment trusts held in the growth investment quota.
Starting in 2024, I have purchased 400,000 yen of US semiconductor stock funds (SOX) every year,
for a total investment of 1.2 million yen.
As of the end of September, the unrealized gain is 1.51 million yen, up 129%,
meaning the valuation has more than doubled relative to the invested capital.
SOX dropped sharply from its peak in June through July.
I was frequently receiving notifications when the net asset value dropped by more than 5%,
but since hitting a bottom in mid-September,
it has recovered significantly.
The star marks on the chart indicate
the periods when I bought this investment trust.
For about a year and a half after the NISA started,
there were many periods where I had unrealized losses.
However, since around October of last year,
the stock price has turned upward due to factors such as increased investment in generative AI data centers
and supply shortages and price surges in semiconductor memory.
The entire portfolio remained resilient even in the face of headwinds
NASDAQ 100 is up 51%, while Indian stocks are struggling
The NASDAQ 100,
which has a high ratio of giant US IT companies,
was purchased for 1 million yen each year starting in 2024. Currently,
it shows an unrealized gain of 1.53 million yen, or +51%.
On the other hand, Indian Nifty 50 stocks are struggling.
In January 2024, I bought 1 million yen worth of iFreeNEXT Indian stocks, and in January of last year and this year, I bought 1 million yen worth of Rakuten Indian stocks each.
The portion purchased in ’24 is down 1.6%, and the portions purchased last year and this year are down 15.7%.
Looking at the chart since January 2024, the base price has fallen to near the lowest level during this period,
which is a different movement from the strong US and Japanese stocks.
The reasons are a negative spiral of rising crude oil prices,
high interest rates in developed countries,
and foreign investors selling off India.
Unless the Middle East situation improves and crude oil prices fall,
the stock price slump is likely to continue.
NISA asset value is 14.29 million yen, with an unrealized gain of +36%.
This is the status of my NISA account after 2 years and 9 months, as of the end of September 2026.
The total investment amount is 10.5 million yen,
the unrealized gain is 3.79 million yen (+36%),
and the asset value is 14.29 million yen.
The unrealized gain as of the end of August was 3.85 million yen (+37%), so
compared to a month ago, the asset situation is almost flat.
There is an anomaly where stock prices tend to fall in September,
and there were also headwinds such as rising global interest rates and soaring crude oil prices.
Even so, funds flowed into large-cap high-tech stocks,
centered on AI and semiconductor-related stocks,
and in the end, it turned out all’s well that ends well.
In mid-September,
the unrealized profit/loss ratio temporarily fell below 30%, but
stock prices recovered toward the end of the month.
The background to this is corporate performance.
The earnings growth rate of S&P 500 companies is
up 35% this year compared to the previous year, and although it does not reach the 51% in 2021, which jumped due to the reaction to COVID, it is in excellent shape.
The earnings growth forecast for 2027 is plus 15%
, and although the growth rate is slowing down,
it exceeds the median annual growth rate of 10% over the past 35 years,
which is making Wall Street bullish.
India is struggling, but
I think I can buy it cheaply next January as well, so
I plan to invest an additional 1 million yen in the growth investment quota.
Introduction to diversification status and popular funds
Month-end with no unrealized losses and diversified investment
Looking at the stocks held in NISA,
the ratio of US IT and semiconductor stocks is high.
However, in my specific account, I also buy Japanese and US investment trusts,
gold, and individual Japanese stocks,
and overall, I am investing by diversifying investment targets, countries,
and products.
It is important to diversify investment targets, but
which investment trusts should I actually choose,
and how should I go about buying them?
Previously, I summarized the differences between All Country, S&P 500, NASDAQ 100, and FANG+, as well as the risks to keep in mind for long-term investing,
incorporating my own experiences.
If you are interested in how to choose investment destinations or how to think about stock ratios according to your age, please read this article as well.
Let’s also look at the graph of the investment amount and valuation at the end of each month for NISA since January 2024.
The orange line is the valuation, and the light blue bar graph is the cumulative investment amount.
If the gap between the orange line and the bar graph widens, the valuation profit is expanding,
and if it falls below the bar graph, it means a valuation loss has occurred.
Since the end of April 2025, immediately after last year’s Trump tariffs,
there has been no valuation loss at the end of any month.
As the investment period gets longer,
the performance seems to be stabilizing.
Conclusion
Two years and nine months since the start of the new NISA,
against an investment amount of 10.5 million yen,
the asset value has reached 14.29 million yen (+36%).
While the S&P 500, semiconductor stocks, and NASDAQ 100 have been solid,
Indian stocks have continued to face headwinds,
resulting in mixed fortunes for different stocks.
Even so, corporate earnings have outweighed the headwinds,
and there has been no valuation loss at the end of the month since the end of April 2025.
I would be happy if this could also serve as an opportunity for you to reflect on your own investment situation.
This time, I disclosed the performance of my NISA account.
However, as I mentioned in the text,
I also invest in gold and stocks in a taxable account,
and the majority of my assets are actually managed there.
I would like to introduce this on another occasion as well.
