Do Threshhold Levels Affect Performance of Portfolio Based On Threshhold Rebalanced Strategy?

I define threshold rebalancing as this: when the market tracking index fund's value is different than the target and the diference is bigger than the threshhold, I rebalance the portfolio. If the stock position has more value, I sell stock and buy otherwise in order to achieve the target allocation ratio. This means the lower the threshhold or the more the stock price flucturates, the more frequent we rebalacnce our portfolio,

Simulator

This simulates the investment restuts of a SPY/Cash portfolio rebalanced with different thresholds. The portfolio starts with $1,000 and SPY initial price is $400.Adjust the cash return to represent short-term bond yield.
Cash Ratio: %
SPY Ratio: %
Mean Monthly Return: %
Monthly Return Standard Deviation: %
Cash Mean Monthly Return: %
Investment Duration: year(s).
Threshold 1: %.
Threshold 2: %.
Threshold 3: %.
Threshold 4: %.

Sharpe Ratios

Conclusion

Investment Portfolio rebalanced with threshholds almost always has a better Sharpe ratio then the non-rebalanced one. But the threshold levels do not have significant impact on portfolio performance.

Which Asset Class Had the Best Performance During the 2008 Financial Crisis?

In this article, I want to explore which asset, ETFs, MFs, Stocks, did best during the 2008 financial crisis. I will compare the investment results against the result of SPY, since it represents the overall market. The scenario is investing right at the highest point of S&P 500 index right before it crashed during the crisis. The date is Oct 9, 2007  when the index reached 1,565.15. I will compare the returns of each asset against SPY in the following order: Investing until the bottom of the crisis at 676.53 on Mar 09, 2009 in order to simulate downside risk. Investing until the S&P 500 index closed above the previous high at 1,568.61 on Apr 09, 2013 in order to simulate recover ability. Investing until the bottom of the Covid crisis at 2,304.92 on Mar 20, 2020 in order to simulate a series of market crashes. Performance By Ranks Oct 9, 2007 to Mar 09, 2009 SHY  return is 8.848% AGG  return is 7.390% LQD  return is -6.793% HYG  return i...
