Of the 100, create a strategy that rebalances all of them every month at equal weight.

Description:
This portfolio implements a monthly rebalancing strategy for the top 100 stocks by market capitalization from 2021. The strategy will maintain equal weight across all 100 stocks, allocating approximately 1% of the portfolio to each position. By rebalancing monthly, the portfolio will systematically adjust positions to maintain equal exposure across these large-cap stocks, which include technology giants like Apple (AAPL), Microsoft (MSFT), and Google (GOOG), as well as leaders from other sectors such as healthcare (UNH, JNJ), finance (JPM, BAC), retail (WMT, HD), and energy (XOM, CVX). This approach provides broad diversification across the largest companies in the market while preventing any single stock from dominating the portfolio's performance. The initial portfolio value is set at $10,000, and the rebalancing will occur when at least 30 days have passed since the last rebalancing action.

Of the 100, create a strategy that rebalances all of them every month at weights relative to their market cap

Description:
This portfolio implements a monthly rebalancing strategy for the top 100 stocks by market capitalization from 2021. Unlike an equal-weight approach, this strategy allocates funds proportionally based on each company's market capitalization, giving larger companies like Apple (AAPL), Microsoft (MSFT), and Google (GOOG) a greater percentage of the portfolio than smaller companies at the bottom of the list. By rebalancing monthly, the portfolio will systematically adjust positions to maintain proportional exposure based on market cap, which naturally gives more weight to the largest and potentially most stable companies while still providing diversification across all 100 stocks. This approach aligns the portfolio with the actual market representation of these companies. The initial portfolio value is set at $10,000, and the rebalancing will occur when at least 30 days have passed since the last rebalancing action.

Of the 100, create a strategy that rebalances the top 50 by market cap every month at equal weight.

Description:
This portfolio implements a monthly rebalancing strategy for the top 50 stocks by market capitalization from the list of 100 largest companies as of 2021. The strategy will maintain equal weight across these 50 stocks, allocating approximately 2% of the portfolio to each position. By rebalancing monthly, the portfolio will systematically adjust positions to maintain equal exposure across these large-cap stocks, which include technology giants like Apple (AAPL), Microsoft (MSFT), and Google (GOOG), as well as leaders from other sectors. This approach provides broad diversification across major companies while preventing any single stock from dominating the portfolio's performance. The initial portfolio value is set at $10,000, and the rebalancing will occur when at least 30 days have passed since the last rebalancing action. For transparency, the full list of 100 stocks is included in the strategy, allowing the system to dynamically select the top 50 by market cap at each rebalancing point.
