The Motley Fool is at it again, this time with Intel. The pitch is familiar: the stock has pulled back, and a $1,000 investment today could make you richer by 2030. And of course the article arrives with a specific dollar figure attached, down to the dollar, the way these predictions always do.

I wrote about their Micron prediction last week, and I have to hand it to them, they're consistent. Consistently confident, anyway.

The bull case isn't crazy on its face. Intel has pulled back hard, and if the company executes on its foundry ambitions, the stock could re-rate. Turnarounds do happen. I watched Intel dominate in the '90s when nobody could touch the Wintel pairing. Companies that fall behind can catch up.

But there's a gap between "could" and "will," and that gap is where these predictions lose me. Any figure stretched out to 2030, stated to the exact dollar, carries a precision the underlying business cannot support. In my experience, company management itself doesn't know what foundry revenue will look like two or three years out. An analyst writing a number four years into the future to the exact dollar is doing performance, not analysis.

Maybe it works out. Genuinely, maybe it does. But semiconductor turnarounds are brutally hard, and I'd argue Intel's attempt has already humbled the executives who have tried to pull it off. That's my read, not a statistic, but it's a read built on watching this company stumble through the better part of a decade.

Here's my standard reminder, and regular readers can recite it with me now. A $1,000 bet on one company is a bet, not a plan. If you own Intel inside a broad index fund, as most of us do, you already have exposure to any upside, capped at Intel's weight in the index but also cushioned if the turnaround stalls for another five years. That second part matters more than people think.

If you believe in the turnaround specifically, then size it like a belief. A position of 2 to 4 percent of a portfolio can pay off nicely without wrecking your retirement if the foundry dream stays a dream. What you shouldn't do is take a headline number, divide it into your savings goal, and work backward to how many shares you need. That isn't investing. That's borrowing against a stranger's guess.

Intel at a beaten-down price is at least a more honest speculation than most. Unlike the sub-$5 story stocks I've written about lately, this is a real company with real revenue and a plan. But a plan and a prediction are different animals, and only one of them writes checks it can cash.

As always, this is my perspective, not professional financial advice. The Fool might be right. I'd just rather not bet the retirement on it.
