This CNBC report on the collectibles market is a little hard to parse. Robert Frank says that according to a Knight Frank and WealthInsight report, cars had the greatest rise in value last year followed by coins. But when you ask the Ultra High Net Worth crowd—167,000 of them around the world, according to the report—what they plan to buy next, Frank says in the video that it 44% of them are looking to buy art.

But in the text of the post, the wording is a bit vague:

And art is still popular with the wealthy, since many see it as more than a financial investment. The survey showed that among people worth $30 million, art is “growing in popularity” among 44 percent of them—making it the most popular class of collectibles.
