There are many here that will say VTSAX all the way. What other fund are you considering and why?
My portfolio is not currently set up like this, but I am working towards it. Just exchanged all of my target date funds for VTSAX and whatever the international version is. JLCollins thinks the international portion is unnecessary, and I'm inclined to agree, but I just happened to remember re-read about that after I did my exchange.
It takes some guts to stick out such an equities heavy portfolio, but I think in the end it is worth it. In February 2014, the market was looking great, and despite this, I lump sum invested 80K into a taxable account, having exhausted my tax-advantaged options. (I put 30% in bonds and 70% in equities, since this was a taxable account and I was thinking about buying a house, and wanted to be conservative. 4+ years later, I still don't have a house, don't know if we will ever buy one, and all the bonds have done was limit my upside. Although, I will say in defense of these bonds, less so than my still cash heavy position as done. Future investments are going VTSAX.
The market is always on a run up, except when it's not, and when it's not, you just buy more if you can. I think your VTSAX heavy portofolio is a really good way to go.
