The REIT etf is a basket of REITs, so if the market downturn affects every REIT in the etf, the etf will react accordingly.
Having a basket of REITs also protects you from having to subscribe to individual rights issue or a collapse of a single REIT. You get some form of diversification.
The etf will rebalance accordingly if there is a rights issue to maintain the portfolio allocation for each reit.
