Thoughts on a quality & momentum based ETFs portfolio for my taxable brokerage account?

I am still learning about all the ETF options available but I built the following distribution for my taxable brokerage account which I would prefer to be light on volatility incase we needed to get some funds out in an emergency:

VFMO 40.00%

IDMO 20.00%

JQUA 30.00%

GLDM 10.00%

The goal here was to have a diverse momentum-based growth portfolio in VFMO (US markets) and IDMO (International) while also staying protected from volatility using JQUA as the quality ETF and GLDM for any major events forcing a significant drawback.

Here is a backtest of it in portfolio visualizer although the range is limited

I also created 2 more portfolios there by adding 10% SPMO and 10% QMON but the former's heavy investment in NVIDIA and other tech companies while having a 6-month rebalancing schedule makes me wary to go for it while the latter did not change much in the metrics.

Let me know what you guys think and if there are any potential updates i should make to it, thanks!
