Seven stocks (Amazon, Apple, Alphabet, Meta, Microsoft, Nvidia, Tesla) added $5.1 trillion to their market cap in 2023, accounting for about 55% of the $9.2 trillion added during the year by all 6658 US firms. bit.ly/4bsNEcB
Going back a decade, these seven stocks have climbed from 8% of the value of all US firms to more than 24% of the value, with 2022 the only serious drawdown year. At a $12 trillion market cap, the Mag Seven are now worth more than all listed Chinese stocks. bit.ly/4bsNEcB
A US stock portfolio created in Dec 2012 without the Mag Seven stocks in it, would have had a shortfall of about 18% in cumulated value by the end of 2023, relative to a portfolio with these stocks. Small stock and value investors suffered! bit.ly/4bsNEcB
One explanation for the Mag Seven performance in 2023 is that it represented a recovery from a catastrophic 2022, when these seven stocks lost $4 trillion in market value. But it is only partial, since they outperformed other 2022 losers. bit.ly/4bsNEcB
Another is that is these companies are being rewarded for their superior business models, with pricing power, in the face of inflation, earnings growth, in the face of economic challenges and very little debt overhang. bit.ly/4bsNEcB
A third and longer term explanation is that these companies (Google, Meta, Amazon) are either already examples of winner-take-all phenomena in their businesses, or perceived (Tesla & Nvidia) to have a chance of getting there in the future.
The Mag Seven are clearly great businesses, but to assess whether they are good investments, you have to get a mismatch between your perceptions of a company and other investors' perceptions of the same company. bit.ly/4bsNEcB
The problem with using pricing ratios to make this assessment is that they are blunt instruments, and are difficult to adapt to reflect differences in growth and risk across companies. The Mag Seven trade at premium prices, but is the premium too high? bit.ly/4bsNEcB
Intrinsic valuations require assumptions that will be always wrong, in hindsight, and your best estimates for the future. That said, they represent a tool that I use to convert my perceptions of a company into value. bit.ly/4bsNEcB
With the addition of Tesla two weeks ago, I own all seven of these stocks, but the other six have been in my portfolio for much longer. I can live with the mild over valuation in $GOOG, $AAPl, $AMZN & $META, and even the larger over valuation in $MSFT. bit.ly/4bsNEcB
$NVDA is a bridge too far for me, and having halved my holding In Nvidia last summer, I plan to halve it again now. I have left money on the table by doing so, but there is no point having an investment philosophy, if you don't act on it. bit.ly/4bsNEcB

In 2025, there were multiple news stories (tariffs, US government ratings downgrade, US government shutdown and Fed independence) that depleted trust in US institutions, and I look at how that played out in bond, currency, precious metal & crypto markets. bit.ly/4q3y6SC
The bond market, where buyers are trusting governments not to default and to protect buying power (by controlling inflation), took the "loss of trust" new stories in stride, with US treasuries flat (20 & 30 yr) or lower (10 yr & below) for the year. bit.ly/4q3y6SC
One reason for rates not moving may be that the Moody's downgrade was not news to the market, which had already priced in that expectation, given that S&P (2011) and Fitch (2023) had downgraded earlier. The sovereign CDS spread for the US dropped in 2025. bit.ly/4q3y6SC
It is the end of the first full week of 2026, and as has been my practice every year for the last 33 years, I have updated the data on my webpage, reflecting the 2025 financial filings of publicly traded firms and updated market information. bit.ly/3YtTCVx
My data universe includes 48,516 publicly traded companies, listed across global markets, and my datasets include global numbers as well as for sub-groups. bit.ly/3YtTCVx
I report on the industry averages on a range of variables (about 200 in all), reflecting data that I use in corporate financial, valuation and investing analysis, striving for consistency and transparency. bit.ly/3YtTCVx
I am on sabbatical this academic year, and while I will not be teaching my corporate finance & valuation classes at NYU in Spring 2026, the full versions of my Spring 2025 classes, with lectures, class material and tests/exams are accessible online. bit.ly/3Y87KDx
NYU offers certificate versions of my valuation, corporate finance and investment philosophy classes, with valuation in both fall and spring, corporate finance in the fall and investment philosophies in the spring. execed.stern.nyu.edu/collections/ta…
If the NYU price tag is off-putting or budget-busting, I offer free versions of all three of these classes, as well as four others, with recorded lectures and supporting material. Since they are free, they come with a money-back guarantee. bit.ly/3XFnMoj
Nvidia breached the $5 trillion market cap a few weeks ago, and even after giving back a chunk, it is one of a dozen companies with market caps exceeding a trillion. Overpriced stocks or Business marvels? bit.ly/3Ycei3W
Debates about over pricing quickly devolve into shouting matches between one side that argues that a trillion dollars is too high a price for any company and the other pointing to a changed world order for business. bit.ly/3Ycei3W
Rather than take that path, I use an intrinsic value framework to reverse engineer the revenues that the company will need to generate to break even at its current market cap, hopefully creating the basis for a more business-based debate about value. bit.ly/3Ycei3W
Channeling Greenspan from the 1990s, Jerome Powell described US equities as “fairly highly valued” which may be Fed code for stocks are in a bubble. I wrote this post to examine whether markets are overpriced, and if so, whether action is warranted. bit.ly/4gXOscz
Looking at the first three quarters of 2025, there is a disconnect between the news of economic disruption and costs, and what equity indices in the US have been doing. Markets clearly are at odds with experts and economists. bit.ly/4gXOscz
Taking a deeper dive into US equities, and looking at market performance, by sector, this is a market that has spread its wealth unevenly, with technology and communication services on the upside, and health care and consumer staples lagging. bit.ly/4gXOscz
Imitation may be the best form of flattery, but not if it is used in a scam. In response to an Instagram scam, where I (allegedly) invite people to invest with me, I cycled through surprise, anger and frustration, before settling on curiosity & graded it. bit.ly/4mtKKcg
I start by describing why I leave material on open access (not altruism, but selfishness) and how you can find any content I have created (written, spoken) online on one of four platforms. bit.ly/4mtKKcg
The first is my webpage, where you can find all material related to my teaching (my two regular and four ancillary classes), data (industry averages), spreadsheets/tools, books and papers. bit.ly/4mxqvKR
