A study of the detriments/benefits of the screen where you buy the top 10 or 5 or 1 1-year momentum Nasdaq100 stock(s) and hold for a month, then repeat.
First year and this year are partial; all other years the full year.
Even with a realistic spread you double the Nasdaq100 with the same drawdown risk except for 1 stock (which has a worse maximum drawdown).
I presented each year's results without the assumed spread. As you can see most years' CAGR beats the Nasdaq100's. Not a greater number of losing calendar years than the Nasdaq100 itself had.
The main negative to note is there would be MANY big drawdowns in MANY years but in those same years usually the strategy would make it back by year's end.
