Hi Clive,sounds like you are thinking along the lines of my HiLowdemo spreadsheet. I lost my password so I can't unprotect it. But it is similar to what you describe. In my spreadsheet, one does not use all that P/E stuff. just how high and how low you think the prices will go. so you could have a wide spread or a narrow spread in price ranges. The range you can change month by month. The ratio of cash to stock is fixed in the beginning when you setup the plan. I have been thinking that one could change the cash/ stock ratio over time. Say a young man could start out with a large range of ratios, like 20:80. then as time passed start changing the ratio to 50:50.. That's high price/ low price stock ratios. not sure if that make any sense. late at night here in Texas.
