LaunchTower Factor Screen — 2026-09-15: The AI Trade Rotates From Equipment to Components
By LaunchTower · 5 min read · Full report · Raw data (CSV)
Every month, LaunchTower runs the same screen on the same 95-ticker universe: a z-scored blend of 12-1 month momentum (50%), 1-year Sharpe ratio (30%), low volatility (10%), and low drawdown (10%). No discretion, no narrative, no "this time is different."
This month, the screen told us something concrete: the AI trade has rotated from semiconductor equipment to semiconductor components.
What changed since 2026-09-14
| Ticker | Prior rank | New rank | What it makes |
|---|---|---|---|
| MU | 1 | 1 | HBM memory |
| LITE | — | 2 | Optical transceivers |
| WDC | — | 3 | Nearline storage |
| STX | — | 4 | Nearline storage |
| INTC | 2 | 5 | CPUs / foundry |
| AMAT | 3 | 6 | Semi equipment |
| TER | — | 7 | Test equipment |
| MRVL | — | 8 | Custom AI silicon |
| COHR | — | 9 | Optical components |
| AMD | 4 | 10 | GPUs / CPUs |
Six of the top 10 are new entrants since last month. The names that fell out of the top 10 (LRCX, MPC, ASML, CAT, KLAC, FDX) are equipment makers, energy, and industrials — names that were leading the screen three weeks ago.
Why this matters
The AI capex cycle is now showing up in the P&Ls of the names that actually ship the HBM, transceivers, and nearline drives that data centers consume. Equipment makers (AMAT, LRCX, KLAC) remain in the top half of the screen but have lost their top-10 positions. The money is rotating from the pick-and-shovel names to the shovel names.
Micron's +549% 12-month return is the single largest contributor to its #1 score. Lumentum's +462% run is the second-largest, driven by 800G/1.6T optical transceiver demand for AI clusters. Western Digital and Seagate — the two nearline storage leaders — are both in the top 4 for the first time in this screen's history.
The bottom of the table
The weakest risk-adjusted profiles in the universe are a mix of consumer software (HubSpot, Intuit, Trade Desk), gaming (Roblox), China-exposed names (Tencent Music, Grab), and high-beta crypto-adjacent (MicroStrategy). All 10 carry negative 12-month returns and negative Sharpe ratios.
Methodology (reproducible)
import yfinance as yf
import pandas as pd
import numpy as np
# 1. Fetch 2y daily closes for the 95-ticker universe
# 2. Compute:
# - 12-1 momentum: close[-22] / close[-252] - 1
# - Annualized vol: std(daily_returns, 252d) * sqrt(252)
# - Sharpe: mean(daily_returns, 252d) * 252 / annualized_vol
# - Max drawdown: min(close / cummax(close) - 1) over 252d
# 3. Z-score each component across the universe
# 4. Composite = 0.50*z_mom + 0.30*z_sharpe + 0.10*z_lowvol + 0.10*z_lowdd
# 5. Sort descending
