Self Recommending: "One Hundred Years in the U.S. Stock Markets" by Hendrik Bessembinder. A century of data for nearly 30,000 U.S. public companies. Fun fact: "Shareholders' wealth was enhanced by $91 trillion over the century, but long-term investors in nearly 60% of stocks incurred wealth reductions." papers.ssrn.com/sol3/papers.cf…

What are Treasuries good for? They clearly aren’t the antidote to bear markets that investors widely believe them to be, @nirkaissar says bloomberg.com/opinion/articl…

President Trump’s campaign promised voters lower prices, higher wages and a massive deportation campaign. What has he achieved? Bloomberg Opinion analyzed 12 metrics to cut through the political noise bloomberg.com/graphics/2026-…

That was fun, thanks for having me!

The bond market has a reliable record of sounding an alarm when companies are in danger of defaulting on public debts. Private credit have no such transparent system, and that's a problem, @nirkaissar says (via @opinion) bloomberg.com/opinion/articl…

More private debt is now issued every year than comparable public debt, except there's no market to warn of defaults. My latest @opinion. bloomberg.com/opinion/articl…

This may well be the year we question putting humans behind the wheel and get the world’s first trillionaire, @nirkaissar says (via @opinion) bloomberg.com/opinion/articl…

What makes Warren Buffett special doesn’t show up in a stat sheet, @nirkaissar says. Here’s what Wall Street can learn from the Oracle of Omaha 🎥

As the recent volatility in risk assets has some investors worrying about leverage, Bloomberg Opinion columnist @nirkaissar says the biggest leverage risk is not actually in the market, but hidden in investors' portfolios bloom.bg/3L0AICt

My latest @opinion: The trouble with leverage is not in the market but in our portfolios. bloomberg.com/opinion/articl…

With the Dells' $6.25 billion giveaway to kids in the US, there may be momentum to go further and fund retirement at birth, an idea I've been banging on about for a long time. Just $10K invested at birth for 70 years in the S&P 500 should grow to about $1.8M in today's dollars, providing a far richer retirement than social security, and for a fraction of the cost to taxpayers. My latest @opinion. bloomberg.com/opinion/articl…

"Sound macroeconomic management — not the same as “big government” or “small government” — promotes trust, and that the main test of sound macroeconomic policy is low unemployment and (especially) low inflation. But there’s another more unsettling implication: Declining trust will be self-reinforcing if, as seems likely, it makes sound macroeconomic policy more difficult." @clive_crook bloomberg.com/opinion/articl…

The through line around Nvidia, Berkshire's Alphabet purchase and Big Tech/AI generally is a bet that their high profitability/moats will generate enough growth to justify premium valuations. For Berkshire, that's not a typical Buffett bet. But it's also not your classic speculative bubble. My latest @opinion. bloomberg.com/opinion/articl…

Elon Musk isn’t the only soon-to-be trillionaire. @nirkaissar says it’s likely we’ll have as many as seven of them in the next few years 🎥

The way to break up the enormous influence a small group of fund companies and proxy advisers have over American business is to give fund investors the right to vote. My latest @opinion. bloomberg.com/opinion/articl…

If you're bothered by billionaires, get ready because trillionaires are coming, and sooner than you think. Some loud voices aside, most people don't hate on billionaires. They're bothered more that too many Americans struggle to get by. The answer is to lift the bottom rather than topple the top, and we can do that by giving companies incentives to grow wages alongside earnings. My latest @opinion. bloomberg.com/opinion/articl…

Warren Buffett is a rare investor and a rare man, writes @nirkaissar. And there may never be another money manager like him bloomberg.com/opinion/articl…

Before Congress created the SEC in the 1930s and began requiring financial disclosure from public companies, they routinely withheld information from investors or mislead them altogether, contributing to the 1929 crash. The same is now true of the $23 trillion US private asset market. My latest @opinion. bloomberg.com/opinion/articl…
