I won't go into details about the specific meaning of "Beta coefficient". If "Beta coefficient" is greater than 1, although the return fluctuation range is higher than the market, the risk is relatively higher than the market. If it is less than 1, the return fluctuation range is smaller than the market, but the risk is relatively high.

It will also be lower than the market, so whether it is better to be greater than 1 or less than 1 is not absolute and depends on market conditions.

If you expect the market to rise, of course choose a fund with a beta coefficient greater than 1, otherwise choose a fund with a beta coefficient less than 1.

In addition, if you cannot judge the future market situation by yourself, if you expect higher returns and can bear higher risks, you can also choose a fund with a beta coefficient greater than 1, otherwise choose a fund with a beta coefficient less than 1.

Finally, I would like to add that the beta coefficient is actually the correlation coefficient * the standard deviation of the fund or stock / the standard deviation of the overall market.

So both beta coefficient and standard deviation can be used to measure risk.
