Stock market is down by 1%, but why is my portfolio down by 2%? š¤Æ
The answer is your portfolio beta is high! ā¬ļø
So, what is Portfolio Beta (Ī²)? š¤
A portfolio's beta (Ī²) is used to measure how risky the portfolio is compared to the index (usually the S&P 500).
For example, if the portfolio's beta is 2, it means that if the stock market goes up by 1% then the portfolio will go up by 2% and vice versa.
Ī² > 1 means your portfolio is more volatile than the index. You're taking an aggressive approach. ā”ā”
Ī² = 1 means your portfolio is as volatile as the index. Its better to switch to Index Funds/ETFs š§š§
Ī² < 1 means your portfolio is less volatile than the index. You're taking a conservative approach. š°š°
-ve Ī² means your portfolio moves in the opposite direction of the index. ā¬ļø ā¬ļø
What is a Good Beta (Ī²)? š
A good beta for you is based on your risk appetite and your goals. šÆ
If you wish to replicate the market performance, buy an Index Fund/ETF. š§
If you are conservative and want to preserve the principal, a lower beta portfolio might be ideal. š°
If you are aggressive and want to generate market-beating returns, go for a higher beta portfolio š. But be tolerant and patient when the market goes down as your portfolio will even go down further. š„
