"Don't Lose Money First" Is Live — Vol.2 of IJin Insight Short Reads


The cover of "Don't Lose Money First" displayed in the investing section of a bookstore.



There is one rule in investing that survives every cycle — every crash, and every bull run that makes it look unnecessary. It is older than any strategy on the market, and it is the easiest to abandon the moment things are going well. Warren Buffett put it as plainly as it can be put: "Rule No. 1: Never lose money. Rule No. 2: Never forget Rule No. 1."

It sounds almost too simple to mean anything. It is not.

The reason the rule matters is arithmetic, and the arithmetic is not symmetric. A portfolio that falls 20 percent needs a 25 percent gain just to return to even. One that falls 50 percent needs to double — a 100 percent gain — to get back what it had. Fall 90 percent, and it takes a 900 percent gain to recover. The deeper the hole, the steeper the climb out, and the climb grows faster than the fall that dug it. That is why a single large loss can erase years of careful gains, and why avoiding the deep drawdown matters more, over a lifetime, than catching the big winner.

Most investing content is about the winner. This one is about the hole.



A steep staircase climbing out of a dark pit toward the light, like the long recovery a deep loss demands.



If you have ever watched a position fall and told yourself it would come back, you already know the feeling the math describes. Sometimes it does come back. The question the rule asks is not whether it returns — it is whether you can survive the wait, and whether the loss was deep enough that the return, when it finally comes, only carries you back to where you started.

That is what the second IJin Insight Short Read is about. "Don't Lose Money First: Five Rules for Investors Who Want to Survive" takes the oldest rule in the business and works through what it actually demands. It lays out five plain rules for surviving as an investor — the recovery math drawn out in full, the behavior that quietly turns a temporary drop into a permanent loss, a short diagnostic for your own holdings, and three portraits of how this plays out in real lives.

It is short on purpose. The idea is old and the math is small; the book's only job is to make both impossible to lose track of.



A single candle flame sheltered behind a low stone wall, like capital protected first before it is put to work.



"Don't Lose Money First" is Vol.2 of IJin Insight Short Reads, a planned eight-volume series published under Aram Press. Like Vol.1, it is priced at $2.99 — a single, deliberate number, meant to be read in an evening and kept. This volume is available wide: on Amazon Kindle, and through every major non-Amazon retailer, including Apple Books, Kobo, Barnes & Noble, and Google Play.

The blog has argued, post after post, that the math you can keep matters more than the math you can chase. Vol.2 is that argument in its plainest form: before you try to make money, make sure you do not lose it. The order is not a slogan. It is the whole game.

The math, as always, gets the larger room. Today Vol.2 joins the blog in arguing for it. Thank you for reading.

Is the Petrodollar Dying? The "Iran War" and the Irony of the Dollar Index

Image
The headlines have been loud all year: "The Era of the Petroyuan is Here." As the conflict between the U.S., Israel, and Iran unfolded, Deutsche Bank and other Wall Street institutions warned that the decades-old dominance of the petrodollar was finally fracturing. The story is compelling, and parts of it are true. But the market data from the crisis told a stranger story than the headlines did. This post first ran in late March, at the height of the Iran conflict. Two months later, with a U.S.–Iran ceasefire reportedly in its final stages, the picture has shifted — and the central paradox it described has, if anything, become clearer. So this is an expansion, updated with where the dollar actually stands as of late May. The Petroyuan Reality Check It is true that sanctioned nations — Russia, Iran, Venezuela — have increasingly turned to the Chinese yuan (CNY) or the UAE dirham (AED) to bypass U.S. sanctions. Saudi Arabia has experimented with China's cross-border dig...

How to Protect Your Wealth in 2026: The Hidden Trap of Inflation

Image
You may have done everything right. Saved diligently. Lived below your means. Kept money in the bank where it felt safe. And still, the house you could have bought ten years ago has quietly moved out of reach. That is not a failure of effort. It is the hidden trap of inflation — and in 2026, the trap is open wider than it has been in years. This post first ran in March. Two months of data have since made its central point harder to argue with, not easier. So this is an expansion, updated with the numbers that have arrived since — including an inflation reading that surprised to the upside as recently as late May. Is Your Money Quietly Losing Ground? The honest framing is not dramatic. It is arithmetic. A dollar held as cash earns whatever your savings account pays. If inflation runs faster than that yield, the real value of the dollar shrinks even while the number in your account stays the same or grows slowly. During the post-COVID era of zero interest rates, this was easy to se...

Microsoft Lost OpenAI. Then It Found Something Better.

Image
The headline that everyone missed On January 29, 2026, Microsoft shares plunged 10% in a single session — wiping out roughly $350 billion in market capitalization. The reason? Investors panicked over ballooning AI infrastructure costs disclosed during Q2 FY2026 earnings. Azure growth was strong, but the capex guidance — well above the previous $88.2 billion annual run rate — sent a clear message: Microsoft was spending money faster than it was making it from AI. Then came the OpenAI narrative. By mid-February, headlines like "Microsoft breaks with OpenAI" and "The $250 billion betrayal" dominated the news cycle. Microsoft's AI chief confirmed plans to develop in-house models under the MAI (Microsoft AI) umbrella, and the stock slid further — bottoming near $355, roughly 36% below its all-time high of $555.45 set in late October 2025. The consensus view was brutal: Microsoft had bet everything on OpenAI, and now that bet was unraveling. The consensus view was als...
