The risk score can change any time? What about REIT+? I aim 2 years because I need to preserve this for property down payment.
2 yrs is quite short a time frame. If I recall, the robos usually talk about at least a five year timeframe to manage risks.
You should ask yourself how much of this you can afford to lose, and how long you can afford to wait if it is below your required amount.

You can do your own study if you don't feel this is relevant. It is about the s&p and not sreits, so you may feel your situation is different.
The upshot is that most bear markets take about a year to recover, and some take 6-8 years.
Just to be clear. I have a small amount in 100% reits, so I'm not saying that we should avoid it. But on the other hand, I don't need the money for at least the next 10 years so I'm not worried if I have to wait out a downturn.
