WBGR-B – Wästbygg Gruppen AB (publ) (STO) | 2-wk Markov

How the Markov model works here

A Markov Chain simplifies weekly price action into states—Down, Neutral, Up—and learns the probability of moving from one to the next. It’s “memoryless”: the next step depends on the current state, not distant history.

We present: Prob. Up Next Week (one-week transition), Prob. Up ≤ k (at least one Up in the next k weeks), Expected Run (typical state duration), and Reward Stats (average weekly returns by state/transition).

Higher Up probabilities / longer Up runs = constructive. Persistent negative rewards or Down bias = caution. Educational only – not financial advice.

Plain-English Interpretation

Current regime: Down.

Short-term odds do not favour an Up move yet. Downtrends here can linger; patience is key if waiting for a turn. If/when it flips Up, rallies often carry for several weeks. Average weekly return while Up is positive - constructive when the regime turns. Down regime carries negative drift - avoid knife-catching. Typical weekly range sits between -0.379 and 0.303 (20th–80th pct).

Reading the metrics

Prob. Up Next Week — one-step transition. Higher values are constructive.
Prob. Up ≤ k — chance of at least one Up in the next k weeks.
Expected Run — typical duration of current state; longer Up runs support trends.
P20 / P80 — typical weekly range for risk sizing.
Reward Stats — average weekly returns by state/transition; negatives flag caution.
