The close lands inside the 7,658–7,780 range the model published that morning: the S&P 500 rises 0.33%

Validated over 1099 out-of-sample sessions, walk-forward: each day is predicted training only on earlier ones, retraining every 21 sessions. It is right 59.69% of the time against 51.14% for the majority class (always calling the more frequent outcome). Brier 0.23474 against 0.24987 with no model.

Of the 139 variables computed (the index, the 500 stocks one by one, VIX, rates, gold, copper and the calendar) the model keeps the 120 most correlated with the target every 21 sessions, chosen using past data only. Today's are listed one by one in prediccion.json.

The ranking is recomputed every session, and this is what moved from one to the next. Next to each move is the factor that produced it: momentum changes every day, value whenever the price does, and quality and growth only when new accounts come in. Why the price moved is not in this data, so it is not told.

Nobody crossed the top 20 line between the two sessions.

The biggest moves in the whole index: COHR climbs 54 places, from #268 to #214 (Momentum 6.9 → 7.5, Value 4.0 → 4.1) and JBHT drops 55 places, from #57 to #112 (Momentum 8.3 → 7.2).

The rare thing on a Form 4 is a purchase. The largest on October 5, 2026: Newlands William A, Director at Hormel Foods Corp /De/, bought 10,000 shares at $20.10 (0.20 million dollars), code P, meaning on the open market and with their own money. see the Form 4 →

1 purchase were filed that day across 1 company. Over the 59 days the file covers, August 17, 2026 to October 14, 2026, there are 199 purchases worth 2,057 million dollars across 61 companies, against 2006 sales: which is why a purchase gets told and a sale gets tabulated. The largest of the whole window was LEN, 134.89 million on October 2, 2026.

The biggest sale of the day tells you nothing. Hershey Trust Co Trustee In Trust For Milton Hershey School, of Hershey, sold 1.6 million dollars of stock and still holds 625,749 shares: that is 1.57% of the position, and the sale was scheduled months in advance under a 10b5-1 plan. That is tax plumbing, not a view on the company.

Of the 3 sales filed that day, 1 was discretionary and 2 scheduled. And here is the finding: the largest sale as a share of holding was discretionary.

The context over those same 59 days: 2006 sales worth 21,404 million dollars (2 with no declared price, outside that total), of which 777 were discretionary, and of those 216 exceeded 25% of the seller's position. That is where to look.

Growth 100 falls short of the benchmark over 27 years: +892.2% against +1,371.7%. The weakest is Growth 100, with an alpha of -1.36%: negative, meaning what it earns does not pay for the market risk it takes to earn it. Publishing the figure that comes out worst is the only reason the others deserve any credit.

Source: carteras.json · index based at 100 on December 31, 1998. Walk-forward with point-in-time data: on each date scoring uses only prices up to that day and fundamentals already filed with the SEC. 332 rebalances through September 22, 2026.

Over the past month the value portfolio lost -0.85% while momentum gained +1.76%. Across that six-month window the benchmark rose 11.2%, so this is not the whole market moving: it is a rotation inside one.

The extreme of the series is March 2, 2000, 27 years ago, at +48.0 points. And what happened after each extreme? Counted, not assumed: of the 5 extremes in momentum's favor with enough data after them, in 2 the lead had flipped sign six months later; of the 5 extremes in value's favor, in 3. That is a count over 10 episodes, not a rule.

• What insiders did yesterday. Form 4 can be filed up to two business days after the trade, so the freshest data is always the day before last.
• Whether momentum keeps winning. 27 years and 332 rebalances are not enough to claim a factor mean-reverts. We can describe what happened, not what comes.
• What any company is worth. This report computes no price targets. No Monte Carlo, no DCF, no fair value. When you see one elsewhere, ask which cost of capital discounted it and who chose that number.
• Whether the S&P rises tomorrow. We measured it with the same model (139 variables) and the same walk-forward protocol, over 1,099 out-of-sample sessions: the model calls direction right 53.41% of the time and saying "up" every single day is right 53.50%. The gap is noise: there is no signal, so we don't sell one. Both figures are recomputed every edition.
