You can watch VNQ, which is the ETF version of the same index fund, to get the minute-to-minute price.
VNQ Vanguard REIT Index ETF, etf, quote, price, shares - Morningstar
I don't own any REITs yet. I don't understand why the value of this fund is still so high. I think commercial real estate will be in bad shape for years.
There are a ton of baby boomers retiring soon and I would think the value of most real estate will be hurt by it. Retirement areas and health care I would think will be the exceptions.
If you compare the US to other countries we have way more retail space available per citizen by huge percentages. I think we are very overbuilt for that kind of commercial real estate.
I wanted to add that I think VNQ is so volatile because lots of people are trading it, instead of buy and hold investors. I also think that is why the share price is not lower. Traders can drive the price up or down irrespective of actual worth. Just think back on the Oil market in 2007 or 2008. Oil went to like 140 or something crazy like that while the whole world was contracting and we were going into a global recession.
