  2. In tough times, many investors turn to tangible assets like gold or collectibles to feel more secure about their investments. These items tend to hold value when other investments decline.
  3. While these assets can serve as a form of insurance in a portfolio, their long-term returns can be low. It's smart to include them for diversity, but they shouldn't be the main focus of your investments.

Diversification: Why is it not working?

Musings on Markets • 0 implied HN points • 08 Oct 08
💰 Finance Portfolio Management
  1. Diversification is important for investors, but its benefits have decreased recently. Investors now see more risks across different markets than before.
  2. The connection between different stock markets has increased, meaning that a crisis in one area can affect many others. This makes diversification less effective.
  3. Real estate risks have become more linked to the stock market because of how properties are now invested in. So spreading money across asset classes offers less protection than it used to.
