So I have about 10k in the vanguard admiral 500 and have had it in there for about 4 months but it is going down. Should I put more money in it since it is at a lower shareprice now or should I start putting money in a different fund like the Vanguard growth ETF?
I am utterly confused by this post. In the 4 months from December 16, 2016 to April 17,2017, the VFIAX (Vanguard 500 Admiral) share price went from $209.50 to $216.97, which is 3.6% growth in 4 months - not even counting the December and March dividends which were a total of about 1%.
You must be referring to the drop from ~$221 on March 15th to the ~$217 on April 17th (it's back up to nearly $221 now on April 27th).
Anyone invested in stocks since November has seen incredible growth, and that's even after an 8 year bull market. If you're concerned about a $4 drop on shares valued at ~$220, you probably need to spend some time thinking about your risk tolerance and desired asset allocation. Don't be the one to panic sell when these shares lose 40-50% of their value over the course of a few months, which they almost certainly will at least once (most likely more) during your investment lifetime.
The forum and wiki at
