The story
As Kioxia shares plunge, an article went viral on 5ch’s News Speed+ board about a husband insisting “if we buy 100 shares now, the price could triple to ¥4 million,” while his wife hesitates over using ¥1.36 million of their ¥2.5 million emergency fund (via her NISA tax-free investment allowance) to buy in. The original piece, republished via Yahoo! News, noted that the couple’s emergency fund would be left with just ¥1.14 million after the purchase. Reactions on the thread were fairly level-headed overall — “¥1.36 million isn’t that big a deal,” “there’s no margin call risk since it’s NISA” — though the discussion branched out into warnings that going all-in on a single stock is basically gambling, comparisons with index investing, and even suspicions that this kind of article might be fabricated for clicks.
[Kioxia Stock] Husband fired up over the plunge: “Buy 100 shares now and we could triple it to ¥4 million!” Is it reckless to pour “¥1.36 million” from a ¥2.5 million emergency fund into “maxing out the NISA allowance”? The “collapse scenario” that leaves just ¥1.14 million behind
(omitted)
With ¥1.4 million left in her NISA growth investment allowance, Ms. A’s husband argued, “This is our chance — if Kioxia triples, we could be looking at over ¥4 million,” and proposed withdrawing ¥1.36 million from their ¥2.5 million emergency fund to buy 100 shares.

What people said
If it's not margin trading, it's not that huge a loss risk anyway
And even if it pays off, it's only ¥4 million
Not even close to a year's salary
Compared to "doing something" to a train (dark joke about suicide after going broke), this is downright cute
This is exactly the scale regular folks like us should be betting at
There once was a company called Toyota, you know — great earnings, stock still went nowhere
\Margin call!\(^o^)/Margin call!/ (chanted in the style of the "Kurumi-chan" anime opening meme)
You can't buy on margin inside a NISA account, so there's no margin call to worry about
Going forward we'll have to foot the bill ourselves for the resources behind the info we want
The real question is whether it's actually worth the cost
Don't even need AI in the first place, honestly
Just run a local LLM
It's not really a mistake though
Stocks are only fun when you trade them like gambling anyway
You'll understand once you "pass on" (a dark pun on wrestler Antonio Inoki's famous line "ikeba wakaru sa" — "you'll understand once you go" — swapped here for 逝く, "to die")
Thank youuuu!!
Inoki's showing up in this thread, I see
everyone will be saying "ah, that was a great dip to buy"
Even if the Nikkei recovers, there's no guarantee Kioxia will
If you're gonna pump it, don't dump it
"What time is it now?"
"Well — roughly, yeah, about then" (a riff on a stock meme reply format)
What is this article even trying to say
Try searching "Financial Field" (the outlet behind this article)
Add a space and the autocomplete suggests words like "pointless," "annoying," "fabricated"
That tells you what kind of site it is
They churn out a ton of these articles
People keep calling it fabricated, but honestly it's a pretty common, relatable scenario. If nobody around you invests, I guess it wouldn't ring true though
I was only talking about the search keywords
Not sure how that turned into a personal attack
Whether it's a common topic and whether this specific article is fabricated are two separate questions
Probably because there are tens of thousands of victims
Because it overtook Toyota (in market cap, briefly)
I think even the index is headed down for a while
The index is down too
Mine's a US index fund — my unrealized-gains cushion went from ¥32 million down to ¥22 million
With index investing you just keep adding regularly and leave it alone for 10-20 years, but that's not enough for some people — they want it to double or triple in a few years, and that's exactly when they end up gambling on a single stock
Well, same as August two years ago or April last year, nothing to do but ride it out
Looking back at my own portfolio's drawdowns — July-Aug 2024, Feb-Apr 2025, and Oct 2025-Mar 2026 — I got hit for about 30% each time
No idea how deep this one will go, but it's already at 30% as of now
The speed of this latest drop is insane
There were a bunch of articles saying it's because earnings came in below forecasts
The earnings themselves were in line with forecasts
It was the Oct-Dec guidance that came in below expectations
And yet its numbers are on par with Toyota's.
Guess the earnings-to-share-price ratio ends up at roughly double Sony's or something?
Background and Key Points of This Discussion
Japan’s NISA growth investment allowance only permits cash transactions, not margin trading, so no matter how far the share price falls, no margin call can occur. That’s the regulatory distinction behind the correction posted in reply to the joking “margin call!” comments in the thread. Kioxia is a stock whose price has swung wildly amid surging demand for semiconductor memory, and the fact that its market cap briefly overtook Toyota’s is the backstory behind the thread’s repeated Toyota references. Meanwhile, the discussion split largely along two lines. One was a difference in how people size up the risk: is dipping into an emergency fund reckless, or is ¥1.36 million a tolerable amount? The other was skepticism about whether the original article — from a “Financial Field”-type outlet — described a real couple’s situation at all, or whether it was fabricated for clicks; since there was no way to actually verify this, readers remained split.
