The Ultimate Guide to Alternative Investing

The wealthier the household, the less of its money sits in public stocks and bonds: family offices keep about 44% of their portfolios in alternatives (UBS, 2025). This report maps that other portfolio across fourteen markets, drawing on the fourteen full dossiers in the Invest Alternative library and the guides beneath them — a library that reached sixty-four titles in September 2026 and is complete.

It reaches three conclusions. First, most of these markets return less than the figure quoted for them: the honest long-run real return on the best-documented collectibles is 2.4% a year for art and 4.1% for wine, against 5.2% for equities, over more than a century. Second, the round trip, the carry and the tax decide the outcome more often than the asset does, and the federal government taxes the gain on most of what follows at up to 28%, not 20%. Third, the wrapper an asset is held in changes its risk more than the asset itself.

Our own IA Composite of these markets stood at 100.27 on September 8, 2026, up 0.29% in a year in which its precious-metals sub-index rose 39.8% and its crypto sub-index fell 41.5%.

Every market receives the same treatment in the same order: the thesis, three defining figures, the honest record, what it costs to own from purchase to sale, the one risk that ends you, how an outsider gets in, and what we are watching. Every figure is lifted from the dossier that covers it and sourced at the end.

The second quarter of 2026 is this report’s opening exhibit, because it shows the two kinds of money in these markets acting on the same price in opposite directions. Gold fell about 16% in the quarter. The London average was $4,506 an ounce, 8% below the record set in the first three months of the year. Western investors withdrew money from gold funds for two months running, and North American funds recorded their weakest first half since 2013. On every retail measure the run had ended.

Over the same three months the world’s central banks bought a net 288.9 tonnes of gold, the largest second-quarter purchase on record and 62% more than a year earlier. Poland bought through the decline to a record 632 tonnes. China extended a buying streak that now runs to 22 months. Uzbekistan, Kazakhstan, Jordan and the Czech Republic all added. The buyers with the longest time horizon on earth treated a 16% fall as an entry price.

That quarter states the report’s argument in miniature. The capital that owns alternative assets in size does not buy them for their headline returns. It buys their shape — a supply that cannot be printed, a coupon that resets with inflation, a bid that does not depend on the stock market — and it sizes each position so that a bad year is an occasion to add rather than a reason to sell.

The fourteen markets that follow are where that capital sits. In most of them the honest return is lower than the figure quoted to the retail buyer, the cost of entering and leaving is higher, and the federal tax rate is 28% rather than 20%. Several are worth owning regardless. The purpose of this report is to establish which, with the arithmetic shown.

This section sets out what the term covers, who owns these assets today, and why the walls that kept ordinary capital out are lowering. The two sections that follow depend on it: the four return engines in section 2 are the reasons the wealthy hold these markets, and the scoreboard in section 3 is what holding them has actually paid.

“Alternative assets” is the catch-all for anything that is not a publicly traded stock, a bond or cash. A case of 2016 Lafite, a Delaware statutory trust holding a warehouse, eleven Gold Eagles in a safe-deposit box and a floor Bored Ape have almost nothing in common except that none of them prints a price on a screen every second. What they share is a set of walls: minimums, accreditation rules, relationships, and a deliberate opacity that kept ordinary capital out long enough for early money to compound in the quiet.

The walls are visible in who owns the assets. Bain’s 2023 Global Private Equity Report put individual investors at roughly 50% of the world’s wealth and just 16% of the capital in alternative funds. College endowments averaged 54% in private and alternative strategies in fiscal 2025 (NACUBO-Commonfund, 657 institutions), the largest of them more. Family offices, on UBS’s 2025 survey, average 44%.

Two structural shifts are widening the door. The money is moving: global alternative AUM was about $16.8T at the end of 2023 and Preqin forecasts $29.2T by 2029. And the public market is shrinking as a venue: the median American company now lists at about fourteen years old, against four in 1999, so more of the compounding happens before you can buy a share.

The third shift is the one the dossiers document market by market: the walls themselves are being sold. A non-traded BDC (a business development company, a fund that lends to mid-sized firms and does not trade on an exchange) takes $2,500, a fractional farm $10,000, a spot bitcoin ETF one share, a fractional Ferrari $50. Every one of those doors is real, and every one changes what you own more than the marketing admits. The rest of this report is, in large part, an account of what each door changes.
