Teledyne Technologies (TDY)
Forward P/E is 27.89x against a peer median of 16.31x, a ratio of 1.71x — well above the 1.3x overvalued threshold and just below the 1.75x bubble threshold — with trailing P/E 29.99x and PEG 2.63. Latest-quarter revenue grew only 9.4% year over year (PRIMARY, EDGAR), so there is no exceptional growth to justify the premium, and trailing earnings are not thin enough to meet the bubble test. Delivered demand check: the Electronics, components & manufacturing group's median growth was 20.4% — demand rising, at more than twice Teledyne's own pace.
What would change this label: Move to FAIRLY PRICED if the forward P/E compresses to about 18.8x or below (1.15x the peer median) at unchanged estimates, or if revenue growth rises above 20% year over year with PEG falling below 1.5. Move toward BUBBLE if the ratio rises to 1.75x or above (forward P/E about 28.5x) while growth stays below 10%.
Teledyne makes respected instruments and sensors, but its shares cost about 28 times expected profit while similar companies cost about 16 times. Its sales grew only about 9%, slower than its peers. You are paying a large premium for slower growth, so the shares look overvalued.
Both lines start at 100 on 2020-09-01. Over the full window Teledyne Technologies returned +108.01% and the S&P 500 +118.28% (price returns; dividends not reinvested). Worst peak-to-trough fall for Teledyne Technologies: -32.2% (2022-04-20 to 2022-10-14). Source: Nasdaq official daily history.

Sales, profit and cash
This company does not report a gross-profit line in its SEC facts (normal for banks, payment networks and some health insurers), so profit is shown as net income instead — gross margin is marked UNVERIFIED-absent rather than estimated.
Free cash flow = cash from operations minus spending on plant and equipment, both from the company’s SEC cash-flow statement. Gaps are quarters where that spending line is not separately tagged in the filings — shown as gaps, never estimated.

The last twelve reported quarters. Full 25-quarter history sits in the data pack behind this page. A dash means the figure is not tagged as a standalone quarter in the company’s SEC facts (the usual case is the fourth quarter, which many companies only report inside the full-year filing) — it is missing, not zero.
Earnings: getting better or worse?
Each box is one quarter’s earnings per share (EPS). Green means EPS was higher than the same quarter a year earlier; red means lower; a dash means the figure is not tagged in the filings.
Basis: GAAP diluted EPS from SEC company facts, compared with the same quarter a year earlier.

What we could not verify
- Gross profit / gross margin: not tagged as a standalone line in this company's EDGAR company facts (common for banks, payment networks and some healthcare payers) — shown as UNVERIFIED-absent; the page charts revenue and net income instead.
- TTM GAAP diluted EPS could not be summed from company facts because at least one of the last four quarters (typically Q4) has no standalone tagged EPS; trailing P/E is therefore taken from the labelled secondary source in valuation_label.md.
- Own-history P/E range not yet compiled for this company in the Phase 1 batch run; the label rests on peer-median, growth and PEG evidence.
- browser.open of statistics page failed with 429 rate limit; values taken from browser.search snippet of the same stockanalysis.com statistics page (crawled 1 day ago)
- CEO full name shown as George C. Bobb in some sources
- Guidance record (each quarter scored against the guidance the company gave the quarter before) is not yet compiled for this company — it is a Phase 2 layer. The earnings strip below therefore uses reported EPS versus a year earlier, which is fully sourced from filings.
The IT factor — the most exciting thing the market is overlooking — is not assessed on an X-Ray page. It belongs to the Deep Dive (Phase 2), where it gets the evidence standard it needs. Leadership-era scoring (the six years split by chief executive) is likewise a Phase 2 layer; this page names the current chief executive only, from a sourced profile.
