<prompt> Human: Im trying to learn about investment options, and Im wondering why anyone would invest in a fund like the Vanguard Ultra-Short-Term Bond Fund Investor Shares VUBFX. Based on its 10 year performance, it looks like it returned pretty much nothing for about 8 years and has returned more, but still not very much, over the last 2 years. Bonds are a bit more risky than money markets, right? So why would anyone choose a fund like this for the years that it performed so poorly?Also, why would this kind of bond fund suddenly begin to win however moderately after so many years of flat returns?There must be something Im not understanding. Can anyone in PF help?link:  <response>: I think you need to work on your reading skillsOf course that fund returned nothing for the first 8 years and only had good returns for the last 2ish years, it was only created 2242015. If you look at the returns chart under the column of Since inception it tells you when the fund was createdThere are funds for everything because there is basically no cost to creating an index fund if someone wants it. Ultra short term bonds are part of a bond portfolio, maybe someone or an institutional investor wants to be able to bias a bit more towardsor against ultra short term bonds for one reason or another, this fund would let them do so.
