PARIS, March 30, 2021 /PRNewswire/ -- Investing tens of millions of dollars in works by Beeple or Banksy may seem extravagant today, but acquiring the most expensive artworks is statistically a winning strategy. Academic studies[1] have shown that a masterpiece effect does indeed exist on the art market: the most expensive works continue to gain more value than the rest of the market. This is corroborated by the analysis conducted by Artprice's valuation service – Artpricing – on the five top-selling artworks in 1999.
