Reconcile — corrected snapshot cash from 128.37 to 128.40017 after authoritative ledger replay; positions and average costs were refreshed to the replayed ledger.

Hold — no trades executed. Authoritative ledger replay refreshed snapshot fields to the logged fills and set CashBalance to $128.40017. Portfolio value = $2378.99 ($2250.59 equities + $128.40017 cash). The 5% reserve floor is $118.95, leaving $9.45 deployable cash. A sub-$9.45 fractional buy would be immaterial after the 0.10% slippage policy and would take cash back toward the reserve floor, so preserving the cushion is the lower-risk choice.

Public quote pages surfaced inconsistent AVGO price formatting in this environment, so Stooq's latest close endpoint was used as the authoritative quote source for valuation today.

Fresh quote retrieval succeeded via Stooq's latest quote endpoint; public Google News RSS headlines were used for context after the web-search tool returned an error in this environment.

April 22, 2026 closes sourced via web search surfacing Google Finance/Yahoo/CNBC quote pages after direct Yahoo Finance chart requests were rate-limited in this environment: AAPL $273.17, NVDA $202.50, AVGO $422.65, GOOGL $339.32, VOO $653.90, SPY $711.21. Position weights remain within policy: AAPL 18.53%, NVDA 20.20%, VOO 18.45%, AVGO 20.98%, GOOGL 16.43%, Cash 5.41%. Market context stayed constructive for AI and broad-index leaders — Apple trades through a CEO-transition headline, Broadcom highlighted strong AI chip demand, Alphabet and NVIDIA remain AI beneficiaries, and the S&P 500/VOO stayed near highs — but with only $9.63 above the cash floor there is no risk-efficient buy to execute today.

Hold — no trades executed. Authoritative ledger replay refreshed snapshot cost bases to match logged fills while keeping CashBalance at $128.37. Portfolio value = $2320.64 ($2192.27 equities + $128.37 cash); the 5% reserve floor is $116.03, leaving only $12.34 deployable cash, which is too small for a meaningful fractional buy after the 0.10% slippage policy.

Position weights remain within policy: AAPL 18.48%, NVDA 20.40%, VOO 18.69%, AVGO 20.43%, GOOGL 16.47%, Cash 5.53%. Market context stayed constructive for mega-cap tech after the recent rebound to record highs, but oil/geopolitical risk and narrow market breadth argue for preserving cash instead of forcing a de minimis add. Yahoo Finance chart requests returned unusable responses in this environment and Stooq now requires an API key, so Stock Analysis closes were used as the freshest accessible quote source.

The 5% reserve floor is $117.56, leaving $10.84 deployable cash. A sub-$11 fractional buy would be immaterial after the 0.10% slippage policy, so preserving cash is the lower-risk choice.

The 5% reserve floor is $115.55, leaving $12.85 deployable cash. A sub-$13 fractional buy is technically possible, but it would be immaterial after the 0.10% slippage policy and would take cash back to the reserve floor immediately, so preserving the cushion is the lower-risk choice. No deposit due today (April 16 is neither the 1st nor 15th; the April 15 contribution is already logged). April 16, 2026 closes from Yahoo Finance chart endpoint cross-checked against Stooq: AAPL $263.40 (-1.14%), AVGO $398.47 (+0.44%), GOOGL $336.02 (-0.33%), NVDA $198.35 (-0.26%), VOO $644.86 (+0.22%), S&P 500 7041.28 (+0.26%). Position weights remain within policy: AAPL 18.36%, AVGO 20.33%, GOOGL 16.72%, NVDA 20.33%, VOO 18.70%, Cash 5.56%. Fresh quotes were available, but GOOGL's April 16 close near $336 remained far above the source used in the April 15 buy log, so this run avoids compounding a provider-discontinuity risk with another trade.

Opened Alphabet position for AI/cloud diversification. Gemini and Google Cloud remain key long-term AI monetization levers, and April 2026 valuation compression leaves GOOGL cheaper than many mega-cap peers while the portfolio was already well exposed to semiconductors via NVDA and AVGO. Fill at $193.97 reflects 0.10% buy-side slippage on the latest available April 15, 2026 close of $193.78.

Reconcile — corrected stale snapshot cash from 101.44 to 101.47 after replaying StartingValue plus all logged deposits, buys, and sells; holdings already matched the replayed ledger.

Reconcile — snapshot cash corrected from 92.06 to 92.04 based on authoritative ledger replay before today's simulation step.

Risk-control trim — sold 0.048 shares of NVDA at $195.92 (0.10% slippage on the April 14, 2026 close of $196.12) after the position drifted above the 25% cap and cash slipped below the 5% reserve. The long-term thesis remains intact, so this was the smallest taxable trim needed to restore policy: cash $92.04 -> $101.44 and NVDA weight back to 25.00%. April 14 market context: S&P 500 closed at 6,823.86 (+0.10%); NVDA led this portfolio's holdings at $196.12 (+3.60% day/day), AVGO closed at $380.78 on continued AI-infrastructure strength, VOO finished at $636.86, and AAPL slipped to $258.79.

Hold — no trades executed. Ledger replay confirmed CashBalance = $92.06 and portfolio value = $1,837.50 ($1,745.44 equities + $92.06 cash). The 5% reserve floor is $91.88, leaving only $0.18 deployable cash — not enough for a meaningful fractional buy after 0.10% slippage, so no purchase is permitted. All positions remain within the 25% max-position rule: NVDA 24.90%, AVGO 24.37%, VOO 23.00%, AAPL 22.72%.
