Oops sorry, it was GoI not agip that asked about the soft landing.
Going back to my experiment on the NASDAQ Index. Yesterday I saw an article on "The Perils of Monte Carlo Simulations". You had to register to see the article, I didn't bother because I'm aware of them and experienced it using Portfolio Visualizer's MC Simulator. In the simulator there are various options, for the simulator you have 4 options; Historical Returns, Forecasted Returns, Statistical Returns and Pararmeterized Returns. I left out FR, but the ran the other 3 for 25 years (matching the data length for QQQ). For PR I used average trading year return of 11.54% and SD of 26.57%, which are the stats for NASDAQ Index (not the NASDAQ 100) From 1/1999 to 1/2024.
The Results:
Being there are no Mutual Funds or ETFs that were indexed to the NASDAQ Index from 1/1971 to early 1999, I used PR Simulator. Annual Trading Year returns were 13.31% and the standard deviation was 21.34%. Results:
Imagine January 1, 2000, making an investment decision on that data and then getting buzz sawed the next 3 years. Also take note of the difference of expected returns in the 3 models of post 1/1999. I believe if you could run a simulation of actual historical returns ante 1999, the results would not be as sanguine as the PR Model, but would not come close to predicting what was to follow.
If you look at the pre-1999 data, Sally Vix was right, there was less risk after a down trading year than an up year. Looking at post 1999 and the entire 1971-2024 historical returns, it's the opposite.
"Sally Vix was right" ... I am going to have to save this and show my wife I am not always wrong! LOL.
