Grownup Escapades: Handling Finances

Take the average high/low price of the S&P500 for a given day from 1970 to 2020, average those out for a given year, and calculate the percent differences year-over-year, plotting those rates out along with the compound interest graph accounting for a.) the raw/actual growth in US dollars (not taking inflation into mind) and b.) consumer-price index adjusted inflation. Hypothetically investing in total market indices like the S&P 500 and the Wilshire 5000 allows us to diversify our investments cross-sector as well as our portfolio, which in turn controls our risk in the market.

This may not seem much, but amounts to more than $5K difference for an initial savings of $100K, or $50K for an initial savings of $1,000,000.
