introduction
There are several aspects that contribute to the value of a portfolio invested in the stock market. This research focuses on how the type of index fund and the frequency of rebalancing affects the value of a self-financing portfolio, containing nine stocks from the S&P 500, over time. The primary index funds investigated are a market cap weighted index, an equally weighted index, and an index fund investing in one unit of each stock. The portfolio will be rebalanced over four different time intervals: daily, weekly, monthly, and quarterly, and the calculations for rebalancing use the adjusted close prices for each stock in the portfolio taken from Yahoo Finance.
