Why does the "Hypothetical growth of $10,000" graph of Vanguards intermediate term treasury fund look so much better than the price history of the same fund on Yahoo finance? I know they're measuring different things but the discrepancy still seems large.
One is based on the share price and one is based on account value, this will make the charts not look exactly the same. I'm sure that Vangaurd factored in reinvested dividends and I image Yahoo didn't. Who knows.
Reinvested dividends. You thought index investing was a meme? Wait till you see the growths with DRIPs.
