PAR vs PROVE: What the Gap Is Telling You

Debbie D. put a good question to us in the forum, and it's one that reaches us in different forms all the time.

Remind me again what adjustments need to be made to my calculations when the PROVE and PAR are further apart, such as JNJ, which currently has PROVE of 6.8% and PAR 3.9%.

First things first. Those two numbers are closer than they look. Think 4% against 6% or 7%. In the grand scheme of a five-year forecast, that's a fairly tight match, and it isn't the sort of gap that should send anybody toward the exits.

The question underneath it, though, is exactly the right one. So let's go forensic.

Two numbers, two questions

It helps to remember that PAR and PROVE aren't two opinions about the same thing. They answer different questions.

PAR, our projected annual return, asks a shareholder's question. Where might this stock take you over the next five years? We always use five years. We build it from a sales growth forecast, a projected net margin, an average P/E, and the projected dividend yield. Assemble those, arrive at a future price, annualize the trip from here to there, add the yield, and you have PAR.

PROVE, our projected return on value, asks an owner's question. What is the whole enterprise throwing off, measured against what it would cost to buy the whole thing? It's projected operating income divided by enterprise value, and enterprise value counts the long-term debt, the current liabilities, the cash and the treasury stock right alongside the market capitalization.

One walks the equity forward through time. The other sizes up the entire business as it sits today. They won't always land in the same place, and there's no particular reason they should.

Where a gap actually comes from

For a good many of the companies we cover, PROVE is the engine underneath the return forecast, and the two numbers are the same figure by construction. For the roughly 2,400 US companies carried in the analyst file, PAR is a judgment. It carries a human forecast inside it: our sales growth number, our margin, our average P/E.

That's where the daylight opens up. Not because the company is doing something strange, and not because one of the numbers is broken. It opens up because of an assumption.

Which means the gap is doing you a favor. Treat it as a smoke alarm on one of your inputs.

The usual suspect is the P/E

More often than not, we start by looking hard at the average P/E.

Consider the arithmetic. The average P/E is the multiple we expect the market to hand this company at the end of five years. Set it too low and the projected future price comes in low, the annualized trip from here to there shrinks, and PAR lands lighter than it ought to. Set it too high and you've talked yourself into a return the business may never deliver.

In the case Debbie raised, that's precisely where we'd deliberate. The average P/E riding inside that PAR calculation looks a wee bit low to us. Lift it to something more defensible and the distance from PROVE narrows on its own, without anyone laying a finger on the company's fundamentals.

While you're in there, the other inputs deserve a glance:

What the gap does not mean

It doesn't mean one number is right and the other is wrong. We publish one return forecast for every company we follow, and we stand behind it. PROVE isn't a rival estimate we run to for a second opinion, and a difference between the two isn't a scandal.

It isn't a signal to act, either. A wider gap is an invitation to audit your assumptions. That's all it is, and that's plenty.

The habit worth keeping

MIPAR, the median projected annual return across every stock we follow, is our market thermometer. It sat at 8.8% in mid-July 2026, running above its long-run average since 2004 of roughly 7.5%. The Sweet Spot travels with MIPAR, five to ten percentage points above it, which put it at 13.8% to 18.8% at the time.

Every one of those numbers is only as good as what goes into it. That's true of MIPAR, it's true of PAR, and it's the reason we keep circling back to the inputs instead of admiring the outputs.

A forecast is a set of assumptions wearing a decimal point. When two of our forward numbers disagree, we don't pick a winner. We go back and check our work, and the checking is where the edge lives. Debbie's question was a good one because it points straight at that habit, and the habit is what raises the probability of success over a long stretch.

We can't help but notice that the investors who do best around here are the ones who treat a surprising number as a question rather than an answer.
