““We can learn to think in this same way. Again, let’s use VTSAX in exploring this idea. Suppose yesterday you said, “Mmm. This idea of owning VTSAX makes sense to me. I’m gonna get me some.” And having said that, you sent Vanguard a check for $10,000. At yesterday’s close the price of VTSAX was $53.67. Your $10,000 bought you 186.3238308 shares. If VTSAX shares are trading at $56 per share a week from now, you might say, “Mmm. My $10,000 is now worth $10,434. Yippee. Mr. Collins sure is smart.””
