Is BRK.B a buy in 2026?

Mixed — Framler currently rates it neutral / hold based on the multi-factor Framler engine score of 43/100. Top drivers: High-quality fundamentals (Novy-Marx gross profitability); Trading cheap to peers (Fama-French value). Framler combines momentum, quality, value, options flow, insider activity and HMM regime detection to score US and international equities daily. This is statistical research, not investment advice.

Is the read supported by multiple factors, or just one?

The page lists how many of the 13 factors point bullish, bearish, or neutral for BRK.B. Multi-factor alignment indicates stronger conviction; a single-factor signal warrants caution.

Is the uncertainty wide or narrow?

Each ticker shows a 90% Mondrian conformal range (Vovk-Shafer 2005) around the score — the band where the ticker's realised 30-day return rank, against the rest of the universe, is expected to land. It is not a price target. The width comes from the calibration bin, not from how much the factors agree.

Is the read confirmed by sector and regime?

Sector score, BOCPD regime classification (risk-on / transition / risk-off), and the active confluence pattern all appear on the page. Aligned context tightens conviction; misaligned context widens the interval and softens the verdict.

What would invalidate this read?

Factor flips week-over-week, a regime shift, fresh earnings, or insider sells are the main invalidators. Scores update daily; the 30-day score sparkline above the factor breakdown surfaces trend drift in real time.

Were we right on BRK.B? — 48 graded days

NO DIRECTIONAL CALLS ON THIS STOCK YET — the score stayed in the middle zone all 48 days. Not knowing, said out loud, is part of the model.

Why so much grey? The score only takes a side when enough of the 13 factors agree on a direction. On BRK.B they have mostly pointed different ways and cancelled each other out, so the honest output was “no call” — the model doesn't manufacture an opinion to have one. Nothing is missing here: across all 1,001 stocks about a third of graded days carry a call; this stock just hasn't been one of them lately.
