It is nearly a year since this was last discussed. It seems that the spread has become a lot smaller, so this is now more of a viable alternative to STW (which I hold, as well as VAS). The holdings have increased from 320K to 1904 K in the last year which appears to have increased liquidity

Since they don't have a tracker like YSTW, I am not sure if it is fairly priced minute by minute. Anyone care to comment?

I hold both VAS and STW because I like competition, quarterly dividends (for absolutely no good financial reason), and Vanguard as a company (I swapped my Vangaurd managed funds for VAS). I wonder if there are algorithms working on arbitraging VAS and STW if they get out of whack?
