Capital stays invested — core and pick both.
This week’s QuantRank
MU — Micron Technology, Inc.
QuantRank: #1
About Micron, briefly
Micron makes memory chips. DRAM and NAND flash, mostly — the memory that sits inside everything from phones to data centers.
Right now, AI hardware is the demand driver. Micron makes high-bandwidth memory (HBM), the memory type AI chips lean on hardest.
A few numbers, as of Friday’s close:
Closing price (Aug 7): $877.57
Market cap: ~$991 billion
P/E (TTM): 19.87
What Micron does:
Products: High-bandwidth memory and DRAM, its two biggest focus areas.
Markets: Enterprise data centers, AI infrastructure, mobile, automotive.
Strategy: Leaning into high-margin enterprise AI. Stepping back from lower-margin consumer retail.
You already know this name. It’s a large, liquid, S&P 500 stock — not an obscure pick. That’s normal for QuantRanks. Most weeks look like this one.
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.
Things to remember every week
This is educational, not advice. I’m sharing what I’m buying, with my own money. You don’t have to buy it too.
This is one QuantRank, published once a week. Nothing more to track between issues unless the market SPY signal flips mid-week.
It’s a quant system. Trust the rank, not your gut. Most QuantRanks come from the S&P 500 — companies you already know by name. That familiarity is exactly what tempts people to second-guess the model. Don’t. The rank did the judging already.
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 name at #1 is a good sign, not a stale one. If a stock holds the top QuantRank for months in a row, 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.
This newsletter is the QuantRank. The method is one link away. Full mechanics, sizing ladder, and honest risk disclosure are in The Patala Core-Plus Strategy.
How QuantRanks predict return
This isn’t a hunch. The model scores a universe of about 450 stocks — mostly S&P 500 constituents, plus some names outside the index — and re-ranks the whole list every month. Run monthly from January 2008 through July 2025 (the last starting month with a full 12 months of forward data to test against), that's 450 stocks × 211 months: nearly 95,000 stock-months scored.
Below is the actual backtest: average 12-month return by QuantRank, shown both as a plain buy-and-hold, and with the SPY market-timing signal applied. QuantRank #1 — this week’s tier — averaged 62% vs 71%, more than double the return of names ranked in the middle of the pack.

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.
