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,

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.
