Collectibles and tangible assets
Watches, art, wine, and classic cars can rise in value, but they're illiquid, expensive to trade, and their reported returns are systematically flattering.
Stories about collectibles sound fantastic because only the pieces that got expensive ever get reported on. The watches nobody wants anymore never show up in any statistic.
Then there are the costs. Auction houses often take double-digit percentages from both buyer and seller. Storage, insurance, and upkeep add more on top.
And trading takes time. You can sell a stock in seconds. For a collectible, you need a buyer who wants that exact piece, and that can take months, or fail entirely at the wrong moment.
As a passion, all of that is perfectly fine. As an investment, it requires expertise built up over years. Buy without it, and you generally pay for that lesson the hard way.
Return figures for collectible markets suffer systematically from selection bias. Indices are typically built from repeat sales of the same item, meaning pieces with no demand simply drop out of view. The resulting survivorship bias considerably overstates the return actually achievable.
Transaction costs are the second dominant factor. Buyer's premium and seller's commission at auction commonly add up to twenty to thirty percent of the hammer price. At an assumed mid-single-digit annual appreciation, simply covering these costs ties up several years' worth of gains.
Economically, these are illiquid, non-standardized individual items with pronounced information asymmetry favoring the professional trade. Where quality and authenticity are hard to verify, the classic market-for-lemons problem arises: the price reflects the uncertainty about quality, and the uninformed participant bears it.
Summary
- Return statistics for collectibles show only the winners.
- Trading costs of twenty to thirty percent tie up years of appreciation.
- Without expertise, the information disadvantage against the trade is large.
Did you get it?
Why are return indices for collectibles distorted?
Because they're based on repeat sales. Items with no demand never show up in them.
How high are typical auction trading costs?
Buyer's premium and seller's commission combined often run twenty to thirty percent.
What's the information-asymmetry problem here?
