Mel Abraham shows how time horizon, not age, drives investment growth. A dollar invested at 20 grows 88 times by 65, but at 30 it grows only 23 times. Adjust your portfolio's mix of stocks and bonds to match your runway, not your birthday.
A person who puts a dollar away at 20 years old at an 8%, an average 8% rate, by age 65 that will go up roughly 88 times. Wait a decade, 30 years old, now it's only going to go up 23 times. So the things you do Will shift based on your age stage and the length of the runway. But that doesn't mean that, oh gosh, I'm now 30, it only goes up 23 times, so let me start trying to swing for the fences every time. Because that's also a problem, because now most of the time you strike out and you never get anywhere. The key is this: if I know that I have a longer runway, I can be a little More aggressive. I would invest more in, in, in investments and equities and everything like that. So what happens when maybe I don't have as much space, as much runway? Does that mean I, I don't invest as aggressively? Maybe not. What it means is the structure of the portfolio changes. It's a structure question more than anything else. I'm going to be 65. My portfolio structure is this— is very different than my son who's 35. He's got decades of more runway than I do. But now I also have commas more than him as far as net worth that allow me to say I don't need to be in a structure that has more exposure. So now I'm gonna be a little more conservative as a structure goes. The interesting thing is he's investing in the S&P 500 just the same as I am. So we have similar investments, it's just structured differently.
