Are Nested portfolio assets rebalanced?

If my Nested portfolio is compounded with 2 ETH at $2K per ETH and 10 COMP at 500$, is it still compounded with 2 ETH if the ETH price rises at $2.5K and COMP price stays at 500$?

Yes! We designed Nested so you won't ever have to bear any impermanent losses. Even if you set your portfolio with weights, initial quantities won't ever change except if you decide to update your portfolio. Rebalancing can then be done manually.
