The Quantum Investing and Discussion Thread

We don’t seem to have a dedicated quantum thread. So let’s start it here.

I sense a

A bit of homework on quantum sensing,
From
Gemini, as I think that’s where the revenue growth is now compared to the speculative hype of the non profitable Q companies:

Teledyne’s ($TDY) backlog is at a record high. However, determining whether it is in a “buy zone” depends on your valuation discipline, as the stock trades near its all-time highs following its Q2 2026 earnings release.

The Backlog & Order Book

Teledyne reported its Q2 2026 financial results, revealing a record funded backlog:

Funded Backlog: ~$5.0 Billion.

Book-to-Bill Ratio: 1.23x overall, driven by a 1.4x book-to-bill in its Digital Imaging segment (which houses space-based infrared sensors and cold-atom optical detectors).

Order Streak: Orders exceeded sales for the 11th consecutive quarter.

2026 Guidance: Management raised full-year 2026 revenue guidance to over $6.53 billion and non-GAAP EPS expectations to $24.45 – $24.65.

Is the Stock in a “Buy Zone”?

$TDY trades around $636 – $640, leaving it moderately off its 52-week peak of ~$697.

The Bull Case (Growth Catalyst):

Balance Sheet: Net leverage sits at 1.1x (a 6-year low), leaving them with a clean balance sheet to execute large M&A deals ($1B+ size) in defense/sensing.

Space & Defense Exposure: Space-based imaging revenue alone is projected to reach $400M–$450M in 2026, growing over 20% year-over-year.

Pricing Power: High-margin proprietary defense sensors afford them resilient gross margins above 43%.

The Bear Case (Valuation Risk):

Full Multiple: At ~26x forward non-GAAP earnings, $TDY is not “cheap” by traditional industrial standards. Historically, buying $TDY when itsown-history P/E percentile drops below 25x forward earnings yields a much safer margin of safety.

Input Bottlenecks: Management specifically flagged supply chain headwinds in germanium and rare-earth magnets as lingering operational bottlenecks.

The Verdict

As a Long-Term Hold: $TDY is a high-quality compounder that provides direct exposure to the quantum sensing, PNT, and defense hardware supply chain.

Tactical Entry (“Buy Zone”): The stock is in a fairly-valued growth zone rather than an obvious value entry. Investors seeking a larger margin of safety typically look for pullbacks toward the $580 – $600 range (~23-24x forward EPS). A dollar-cost averaging approach works well here if you want to establish exposure without taking a full block position at near-peak multiples.

DCA for TDY it is then. :money_bag:

Speaking of quantum sensing:

Legislative Progress (H.R. 9646): Track whether the Quantum-Enhanced Critical Minerals Mapping Act passes into law, as direct USGS integration would establish a recurring federal revenue channel for their gravity gradiometers.

TDY isn’t exactly a pure-play quantum computing company, but too bad they don’t have a weekly options chain. I have a list of quantum stocks that I sell weekly puts on.

IONQ
QBTS
QUBT
RGTI

I’m still holding IONQ— and INFQ.

I don’t have the nards for options though. Probably a good thing.

What kind of $ are you bring in weekly? % wise, not dollar amount.
