How to Find Overvalued Stocks Using Discounted P/E Screener

Learn to spot overvalued stocks with Investorean’s Discounted P/E screener by comparing current and forward P/E to historical averages and peers.

Most investors use P/E ratios to hunt for cheap stocks. Fewer use them correctly to spot overvalued stocks - companies priced far above their historical or forward earnings norms. The Investorean Discounted P/E Ratio Screener gives you exactly the fields needed to do this fast and systematically, if you flip the logic.

Here’s a practical, no-nonsense guide to using it to surface potential overvaluation.

What the Discounted P/E Screener Actually Shows

The screener provides side-by-side valuation context, not just raw multiples. Key fields:

P/E ratio - current trailing P/E
Avg. P/E - company’s historical average P/E
Fwd. P/E - forward P/E based on earnings estimates
Avg. Fwd. P/E - historical average forward P/E
P/E to Avg. - relative comparison vs historical norm
Fwd. P/E to Avg. - forward multiple vs its norm

Most users set these to “below average” to find bargains. To find overvalued stocks, you do the opposite.

Core Principle: Overvaluation = Multiple Expansion Beyond Norm

A stock is potentially overvalued when:

Current P/E is well above its historical average
Forward P/E is well above its historical forward average
Price rose faster than earnings expectations
Multiple expansion, not fundamentals, drives returns

You’re looking for valuation stretch, not just high P/E.

A P/E of 40 is not automatically overvalued if the long-term average is 38.

A P/E of 25 can be overvalued if the average is 14.

Context beats absolute numbers.

Step-by-Step: Configure the Screener for Overvalued Stocks

Step 1: Flip the Relative Filters

In the screener fields:

Set P/E to Avg. → Above
Set Fwd. P/E to Avg. → Above

This immediately filters for companies trading richer than their normal valuation range.

This is the most important move. It turns a value screener into a stretch screener.

Step 2: Add Absolute Valuation Guards

Now tighten with hard limits:

Set P/E ratio → Greater than a threshold (example: > 30)
Set Fwd. P/E → Greater than a threshold (example: > 28)

This removes cases where a stock is only slightly above its average but still cheap in absolute terms.

You want:

High vs history
High vs market norms

Not just one of them.

Step 3: Narrow by Sector (Critical)

High multiples are normal in some sectors and dangerous in others.

Use the Sector filter:

Tech / AI / Software — naturally higher ranges
Utilities / Energy / Financials — lower normal ranges

Overvaluation signals are stronger when a typically low-multiple sector screens expensive.

Example logic:

Utility at 28 P/E → red flag
AI software at 28 P/E → maybe normal

Sector context prevents false positives.

Step 4: Check Forward vs Trailing Gap

Now look at the relationship between:

P/E ratio
Fwd. P/E

If forward P/E is not meaningfully lower than trailing P/E, the market is not expecting strong earnings acceleration.

That means:

Price is high
Growth expectations are not compensating
Multiple compression risk increases

That’s a classic overvaluation setup.

Step 5: Use Market Cap as a Risk Lens

Add Market Cap awareness:

Mega caps with stretched multiples → repricing risk hits portfolios broadly
Small caps with stretched multiples → repricing risk hits violently

Same overvaluation signal — different risk profile.

Patterns That Often Signal Overvaluation in the Screener

When scanning results, watch for:

P/E far above Avg. P/E
Forward P/E also above Avg. Forward P/E
No major forward multiple compression
Sector normally trades cheaper
Recent strong price run (check chart after shortlist)

That cluster is more reliable than any single metric.

What This Screener Cannot Tell You

Be precise about limits:

It does not prove a stock will fall
It does not measure competitive advantage
It does not judge earnings quality
It does not price in new product cycles

It flags valuation stretch, not business weakness.

Some stocks stay overvalued for years. This is a risk filter, not a timing tool.

Best Practice Workflow

Use the screener like this:

Filter for P/E to Avg. = Above
Filter for Fwd. P/E to Avg. = Above
Add absolute P/E floors
Narrow by sector
Export results (CSV button)
Review charts + earnings trend
Check growth vs multiple expansion

Fast. Repeatable. No guesswork.

Bottom Line

Most investors misuse P/E tools to chase “cheap.” The smarter use is spotting multiple inflation vs historical norms.

The Investorean Discounted P/E Ratio Screener already gives you the comparison columns, you just need to reverse the default value-hunting logic.

Overvaluation is rarely hidden. It’s usually visible, if you measure against the right baseline.
