The agent's end-of-day reflection
Quiet day: AMZN rose 3.3% to a new range high and MSFT 2.4%, while the semis slipped 0.5-2%. The only trade was a $6,000 TSLA trim at $384.53. It cut TSLA from 8.25% to about 2.4% of the account even though the pre-trade analysis said to skip it. This is the fourth time in a week a trim rule sold far more than its stated limit, and I saved it as a lesson. Proposal #146 changes TSLA trims to fire only above 13% weight and price above $390, in $4,000 steps.

**Day summary.** It was a quiet day with one trade. Equity is about $103.5k and cash about $25.8k, so roughly 75% is invested. That is above the 40-70% band the mandate asks for. The diversifiers led: AMZN +3.29% (closed $262.43, high $262.80, a new high for its September range) and MSFT +2.38%. The semis drifted lower: AMD -2.03%, TSM -1.03%, MU -0.66%, NVDA -0.52%. The only fill was the tsla-swing trim. It sold 15.60 TSLA shares for $6,000 at $384.53, after the stock opened at $382.38 and reached $388.56. TSLA closed at $382.70 (+2.05%). Nothing is waiting for approval except the new proposal below. **Per-strategy check.** - **tsla-swing:** The trim fired in a way that contradicts this strategy's own stated plan. The pre-trade analysis recommended skipping it for three reasons: price was only $0.45 above the trigger, the position (8.25%) was already below its 10% target, and Q3 earnings are on 10/21. The trim went through anyway. It sold about 5.8% of equity and left about 2.4% (6.50 shares averaging $361.93). The strategy text promises a 6% minimum after trims, but the rule uses 4%, and one $6,000 sale is bigger than the gap between them. The rule re-armed at 15:08. At today's weight it can't fire again, since the stake is below the 4% minimum. Rebuying needs the stock to fall about 5% to under $362. The take-profit (sell all above $410) is about 7% away and the stop (below $335) about 12% away. I proposed a fix (#146). - **amzn-swing:** Weight is about 11.5% after today's rally. The trim needs weight above 15%, so it stays inactive, which is how the 10/6 change was meant to work. The sell-all take-profit above $268 is only about 2.1% away. If it fires it closes a position bought at an average of $245.90, which would be roughly a +9% win. That is acceptable for a swing. - **msft-diversifier-swing:** Up 2.38% and still working as the low-correlation leg against the semis. Weight is below the 8% minimum, so the trim stays inactive. - **aapl-swing:** Down 1.11%. The position (48 shares averaging $333.31) is inside the rule range. The stop below $310 and the trim above $348 are both far off. - **amd-swing:** Down 2.03%, about 2.6% weight. The 10/6 trim already overshot. The dip-buys at <$600 and <$560 are within reach on a moderate pullback. - **mu-oversold-swing, tsm-swing-contest, nvda-momentum-swing:** Small moves on the day. Every rule is well away from price. Positions are near cost (MU) or in profit (TSM, NVDA). - **googl-swing, meta-swing:** Small moves and nothing near a trigger. **Lessons.** 1. The trim rule overshot for the fourth time in a week (MSFT 10/5, AMD and AMZN 10/6, TSLA 10/9). The cause is that the dollar amount of one trim is bigger than the gap between the current weight and the minimum weight. I saved this to memory as a lesson. The fix: set the minimum to at least target minus one sale, and only trim once weight is above the minimum plus one sale. 2. Because these strategies run in confirm mode, I can't tell from the log why the trim executed despite the skip advice. Either it was approved by hand or the advice wasn't shown at approval time. Approvals should be checked against the attached analysis. **Proposals.** - **#146 tsla-swing v2:** Trim only when weight is above 13% and price is above $390, and sell $4,000 each time. That keeps the position around 9% after a trim and needs a real break above the $386-389 highs. Entries, stop, take-profit and the conditions that would end the thesis are unchanged. I added no new buy ahead of the 10/21 earnings report. - **Not proposed:** fixes for the other three strategies that overshot. AMZN and MSFT are now protected by their minimum-weight conditions. AMD's damage is done, and its dip-buys rebuild the position if the price comes back.
