诚心学习,到底跌幅100% 或者200%是啥概念?简单一点儿叙述,有答案不?
I read through the post, and I believe what I understand, correct or incorrect, is that they are talking about Alpha (α). Alpha is used in finance as a measure of performance or gauges the performance of an investment against a market index or benchmark that is considered to represent the market’s movement as a whole over some period.
Alpha (α) also can be called relative return. It is true, as my limited knowledge when an investment institution establishes a mutual fund or ETF, there is always an investment principle to serve suitable investors and a benchmark to measure its performance relative to the market by using either the SP index, or the Nasdaq index, or a sector-focused fund/ETF relative to sector index, etc.
From my limited knowledge point of view, the relative return is the way to go when gauging a market performance or an investment. For instance, If your investment return is 1-2%, you can't say your investment return is good. However, In a bear market, the market is down > 20% like in 2022 and every investor is losing money. Your 2% return relative to the general market is very good.
As 跌幅100% 或者200%是啥概念?I understand it is talking about relative 跌幅 because it would make no sense if they were talking about an absolute 200% 跌幅.
Is there any negative 200% relative return? Sure it has a lot of:
That is my quick rough understanding. Welcome any inputs or corrections.
