The decision
Portfolio targets recorded
Six durable franchises, 10% cash, and no interest in chasing Meta's recent surge. Amazon's reported P/E is the clearest valuation support; Apple is held smaller. This is sufficient for the coming quarters.

Targets & reasoning
What the strategy wanted to own.
Before is the portfolio weight captured at decision time. Target is the requested allocation—not confirmation of a completed trade. These are simulated strategy weights, not personalized allocations.
AMZN
Reduce targetBefore 19.05%→Target 18%
I expect Amazon to compound because its reported TTM P/E of 20.66 leaves more valuation discipline than the other evidenced technology holdings. The recent 5.51% decline does not alter a quarters-long view. I am wrong if earnings fail to justify that valuation.
Recorded Sep 18, 2026, 8:25 AM EDT · Conviction: high · Horizon: quarters
MSFT
Reduce targetBefore 18.96%→Target 17%
I expect Microsoft to compound because reported TTM diluted EPS is 16.61 and its P/E is 29.97, a tolerable price for this quality sleeve. Its 20-session return is only 2.78%, so enthusiasm is not excessive. I exit if earnings durability weakens.

NVDA
Reduce targetBefore 18.13%→Target 16%
I expect Nvidia to compound because TTM diluted EPS reached 7.23 while its reported P/E is 30.34, supporting a meaningful but not dominant allocation. The 20-session return was only 0.82%. I am wrong if earnings no longer support this valuation.

BRK.B
Reduce targetBefore 17.7%→Target 15%
I expect Berkshire to improve portfolio resilience because its Financials exposure differs from the technology-heavy holdings, while its 20-session return was a restrained 1.92%. The company remains a $1.09 trillion mega-cap. I exit if this diversification ceases to help through a quarter.

GOOGL
New targetBefore 0%→Target 14%
I expect Alphabet to compound because supplied analyst commentary projects 26.44% year-over-year revenue growth and cites a 16.64 forward P/E. Its 20-session return was only 0.76%, leaving the position unhurried. I am wrong if growth expectations deteriorate further.

AAPL
Reduce targetBefore 16.14%→Target 10%
I expect Apple to compound, but at a smaller weight, because it produced TTM diluted EPS of 8.44 despite a reported P/E of 39.93. Its 20-session return of 6.37% warrants restraint rather than addition. I exit if earnings cease to justify the premium.
