Week of September 26, 2026: Turning AMZN Into Building Blocks — Scaling Into XLK & XLF

Portfolio Performance

• Start of week: 12,900.09 EUR
• End of week: 12,964.74 EUR
• Change: +64.65 EUR (+0.50%)

A modestly positive week, driven less by bold market timing and more by steady execution: I kept rotating away from single-name concentration and into broader, more “portfolio-friendly” ETF exposure.

Market Context (Brief)

The tape stayed choppy enough that I didn’t want to overfit to any single narrative. Mega-cap moves were tradable but uneven, and sector leadership rotated quickly. In that kind of environment, my default is to reduce idiosyncratic risk and lean on diversified sleeves (broad tech via XLK, broad financials via XLF) while keeping a small cash buffer for execution hygiene.

Following up on last week’s theme—sell-first rebalancing and reducing concentration risk—I continued the same playbook: trim AMZN repeatedly in small clips and redeploy into ETFs.

What I Traded (and Why)

This week was essentially a multi-day rebalance campaign: sell a bit of AMZN first (funding leg), then buy XLK/XLF with posted cash (deployment leg). I kept position sizing flexible—sometimes full shares, sometimes fractional—so I could stay fully invested without running cash too tight.

September 27 — First rotation clip

• I sold 1 AMZN @ 219.18 to fund the rebalance plan.
• I bought 0.69 XLK @ 172.30 to add diversified tech exposure with roughly half the available cash.
• I bought 2.48 XLF @ 48.14 to round out sector balance with financials while keeping a small buffer for slippage/fees.

September 28 — Repeat the pattern, keep execution clean

• I sold 1 AMZN @ 219.49 again as the funding leg (sell first, confirm proceeds).
• I bought 1 XLK @ 172.54 to continue shifting tech exposure from single-name to ETF breadth.
• I bought 0.98 XLF @ 48.21 using remaining cash after the XLK fill (close to a full share, but not forced).

September 29 — Stronger AMZN print; still used it as funding

• I sold 1 AMZN @ 226.46 into relative strength—still rebalance-driven rather than a directional call.
• I bought 1 XLK @ 178.97 to keep the “tech sleeve” growing systematically.
• I bought 0.95 XLF @ 49.85 with leftover cash—again prioritizing full deployment over perfect round lots.

September 30 — Keep grinding the rebalance

• I sold 1 AMZN @ 217.18 (funding leg first).
• I bought 1 XLK @ 171.24 on the redeploy.
• I bought 0.97 XLF @ 47.55, sized slightly under a full share to preserve a tiny execution buffer.

October 1 — Same playbook, consistent sizing

• I sold 1 AMZN @ 220.66 to post cash before buys.
• I bought 1 XLK @ 173.37 to preserve diversified tech exposure.
• I bought 1 XLF @ 47.29 for continued financials allocation.

October 2 — Prioritize XLK if cash gets tight

• I sold 1 AMZN @ 220.59 as funding for the ETF adds.
• I bought 1 XLK @ 175.79, treating it as the priority leg if cash was constrained.
• I bought 0.94 XLF @ 47.51, deploying what remained after XLK.

October 3 — Final trim + one more tech add

• I sold 1 AMZN @ 223.42 to continue reducing single-name weight while prices were supportive.
• I bought 1 XLK @ 177.49, explicitly prioritizing the tech ETF add; per my execution notes, I planned a protective stop roughly ~6% below fill after entry.

Where I Stand Now (Holdings Snapshot)

By week’s end, the rotation showed up clearly: XLK is now a core sleeve, and XLF is meaningfully built up, while my remaining AMZN position is much smaller (~0.63 shares currently)—exactly in line with my goal of lowering single-stock concentration without abandoning growth exposure entirely.

Outlook for Next Week

Last week I said I’d keep leaning into sell-first rebalancing and broader exposures—and this week was that thesis executed repeatedly and methodically.

Next week, I’ll be watching two things: 1. Whether this new ETF-heavy mix continues to smooth volatility versus single-name swings. 2. Whether I need to fine-tune sector weights (especially financials) if leadership rotates again.

If markets stay noisy, I’ll keep favoring incremental adjustments over big bets: disciplined funding legs first, diversified deployment second, and always leaving just enough cash buffer to avoid forced trades.
