I keep track of the following portfolios:

1. NASDAQ 100

   This portfolio selects 5 stocks out of 100 stocks that are part of the NASDAQ 100 index. Stocks are selected based on market conditions. This portfolio gets stellar performance but with it comes high volatility. It considerably outperforms the NASDAQ 100 index (the benchmark for this portfolio) over long periods.

2. Leveraged ETF

   This portfolio consists of 2 leveraged ETFs (Exchange Traded Funds). This portfolio also gets stellar performance and comes with high volatility. It considerably outperforms the S&P 500 index (the benchmark for this portfolio) over long periods.

3. Vanguard

   This portfolio selects 2 funds from 14 Vanguard funds that do not contain bond holdings. The 2 funds are selected based on market conditions. It's much more conservative (less volatile) than the NASDAQ 100 or leveraged ETF portfolio but it still gets very decent gains and considerably outperforms the S&P 500 (the benchmark for this portfolio) over long periods.

4. Vanguard Select

   This portfolio selects 2 funds from 5 Vanguard funds that do not contain bond holdings. The 2 funds are selected based on market conditions. The 5 funds were selected from the 14 funds used by the Vanguard portfolio based on their performance since 1990. Using 5 funds vs. 14 improves performance and considerably outperforms the S&P 500 (the benchmark for this portfolio) over long periods.

5. Simple Vanguard

   This portfolio switches between 2 funds available through Vanguard depending on market conditions and holds only 1 fund at a time. It's a bit simpler than the Vanguard Select portfolio but still gets about the same gains and considerably outperforms the S&P 500 (the benchmark for this portfolio) over long periods.

6. Lazy Vanguard

   This portfolio puts equal amounts in 4 funds available through Vanguard and rebalances once a year. You'll only have to trade (rebalance) once a year but it still gets very decent gains and considerably outperforms the S&P 500 (the benchmark for this portfolio) over long periods.

7. TSP

   This portfolio switches between 2 funds available through TSP (Thrift Savings Plan, a defined contribution plan for United States civil service employees). It's much more conservative (less volatile) than the NASDAQ 100 or leveraged ETF portfolio but it still gets very decent gains and considerably outperforms the S&P 500 (the benchmark for this portfolio) over long periods.
