要点总结
- •Tail risk refers to rare, extreme events with a significant negative impact.
- •These events lie in the 'tails' of a probability distribution, far from average outcomes.
- •Gold is often used as a hedge against tail risk due to its historical role as a safe haven.
- •During crises, gold tends to preserve or increase its value when other assets decline.
- •Its intrinsic value and limited supply contribute to its appeal as a store of wealth.
常见问题
What is a probability distribution?
A probability distribution is a function that describes the likelihood of obtaining the possible values that a random variable can take. Think of it as a map showing how probable different outcomes are. For example, a probability distribution for coin flips would show a 50% chance of heads and a 50% chance of tails.
What does it mean for an asset to be a 'safe haven'?
A safe haven asset is one that is expected to retain or increase its value during times of market turmoil or economic uncertainty. Investors flock to safe haven assets when they are concerned about the performance of riskier assets like stocks. Gold, government bonds of stable countries, and certain currencies are often considered safe havens.
