Signal: BUY.
Capital stays invested — core and pick both.
This week’s QuantRank
LITE — Lumentum Holdings, Inc.
Current QuantRank: #2
Buy Monday, August 17.
Why this pick, briefly
Lumentum makes photonics — components and subsystems built around light instead of electricity. Its two biggest businesses: optical components for networks, and lasers.
On the networking side, Lumentum supplies the optical transceivers and components that move data between servers inside data centers and across telecom networks — the physical layer underneath the AI buildout everyone’s watching. On the laser side, it makes diode lasers used in industrial cutting and welding, telecom, and 3D sensing (the kind of laser tech behind facial-recognition hardware).
A few numbers, as of Friday’s close:
Closing price (Aug 14): $926.14
Market cap: ~$82.056 billion
P/E (TTM): N/A — no meaningful trailing earnings to measure against.
What Lumentum does:
Products: Optical components and transceivers for networking; diode lasers for industrial and sensing use.
Markets: Data center and telecom networking, industrial manufacturing, 3D sensing.
Strategy: Riding the data-center optical buildout — faster networks need more, and more advanced, optical components to move traffic between servers.
This one’s a step less familiar than last week’s pick — Lumentum doesn’t have the household-name recognition Micron does. That’s fine. The rank isn’t asking you to already know the story.
How much to buy
Typical range: 1% to 3% of your capital.
The S&P 500 is at all-time highs right now. If that makes you nervous, size toward the lower end of that range. That’s a reasonable adjustment. Skipping the pick entirely is not.
Things to remember every week
This is educational, not advice. I built this system, and I’m sharing what I personally follow — with my own money. You don’t have to follow it too.
This is one QuantRank, published once a week. Nothing more to track between issues.
It’s a quant system. Trust the rank, not your gut. Some QuantRanks — like Micron last week — are companies you already know by name. Others, like this week’s, aren’t. That’s not a downgrade in conviction. The rank did the judging either way.
Strong predictive power over the long run — no guarantee on any single name. QuantRanks has shown real predictive power over time. That doesn’t stop any one stock, or a string of them, from losing money — in the short run or the long run.
A repeat within ranks 1 to 5 is a good sign, not a stale one. QuantRanks tend to bounce between the top five spots from month to month — if a stock keeps reappearing in that tier, that’s the model telling you conviction is building, not fading. Keep adding on the normal schedule.
No target price, no separate exit. A QuantRank is held until the signal — the market-wide one, not a per-stock rule — tells the whole portfolio to sell.

Why QuantRanks predict return
QuantRank #2 — this week’s tier — averaged 55.5% to 63.2% over the following 12 months in the backtest, across 210 trades. Not quite Rank #1’s number, but well clear of the middle of the pack — this is still top-tier territory, not a step down in what the model expects.
Full backtest methodology and the broader QuantRanks study are in the deep dive.
If the signal flips
Signal turns SELL: Move 80% to 100% of the portfolio to cash or short-term notes — SHV, SGOV, or similar. Core and pick go together. No exceptions for a position you like.
Signal turns BUY again: Restart. Rebuild your core position in SPY or QQQ first. Then resume adding 1% to 3% into the top QuantRank each week, the same as always.
Disclosure: I personally buy this QuantRank, in the live portfolio, every Monday after publication — never before.
