While US stocks have done well, so far, in 2021, the market is caught between two forces, a stronger than expected economy as a positive and worries about inflation as a negative. After a decade of benign inflation, are we ill-prepared for the latter? bit.ly/2RLARxQ
Expectations that inflation will rise are becoming more broad based, as can be seen in both a bond market based measure (T.Bond - TIPs) and consumer surveys. bit.ly/2RLARxQ
Inflation is currency specific, & differences explain why interest rates vary across currencies and exchange rates. Here are expected inflation rates for 2021-26, by country, from the IMF. Given the noise in measuring inflation, take with a grain of salt! bit.ly/2RLARxQ
Higher-than-expected inflation inflicts direct damage on bonds, as rates rise. Their effect of stocks is more complex, with discount rates and cash flows rising, but the net effect, at least in the aggregate, is more likely to be negative than positive. bit.ly/2RLARxQ
The effects of higher-than-expected inflation on nominal & real returns on stocks and bonds can be seen in historical returns over time. Take a look at annual returns in the 1970s (highest inflation) and 2010-19 (lowest inflation): bit.ly/2RLARxQ
Gold and real estate are posited to be inflation-protected, and the evidence is stronger for gold than for real estate, when you look at historical returns. As for cryptos, bitcoin is not behaving like millennial gold yet, but the jury is still out. bit.ly/2RLARxQ
For those who are nostalgic for an era when low PE and PBV stocks delivered superior returns, the silver lining in a high-inflation scenario may be a tilt back, albeit a small one, to old-time value stocks. bit.ly/2RLARxQ
Inflation is here & no one knows whether it is transitory or permanent. If permanent, we could be reverting to more normal inflation, but there is a non-trivial chance that it could be higher. The Fed's happy talk may get in the way of a robust response. bit.ly/2RLARxQ

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/3Ycei3WImage
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/3Ycei3WImage

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/4gXOsczImage
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/4gXOsczImage

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/4mtKKcgImage
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

In the last few years, MicroStrategy has become a Bitcoin SPAC, with investors attributing savant-like status to Michael Saylor. Its success has led some to push companies to shift their cash into bitcoin. As a general principle, this is a bad idea, but there are four carveouts. bit.ly/40TEjXGImage
The reasons for holding cash vary depending on where a company is in the life cycle from survival for young growth firms to youth serum for mature firms to liquidation manager for declining firms. bit.ly/40TEjXGImage
For all of these reasons, publicly traded firms held more than $11 trillion in cash as of June 2025; US firms held about $2.5 trillion in cash. Much of that cash is invested in close-to-riskless and liquid investments, earning low returns. bit.ly/40TEjXGImage

Most investment lessons are directed at long-only investors in publicly traded stocks & bonds, with cash as a buffer. It ignores vast swathes of the investing universe, including private businesses, short strategies & non-traded assets. bit.ly/4l6DOSpImage
These ignored investments are what comprise the alternative investing universe, and in the last two decades, they have been sold relentlessly to portfolio managers, on the promise that they will yield better risk/return trade offs. bit.ly/4l6DOSpImage
The first pitch for alternative investing is based on "low" correlations with traded stocks and bonds, where adding them on to a primarily stock/bond portfolio will generate diversification benefits. bit.ly/4l6DOSpImage
