Winning and losing streaks (consecutive up or down days)

A run of consecutive trading sessions that each closed higher than the one before — or each lower — counted in sessions, not calendar days.

A "winning streak" is simply a run of trading sessions where each close was higher than the close before it; a "losing streak" is the same run of lower closes. The count is in SESSIONS, so a weekend or a market holiday does not interrupt one — five up days in a row spanning a weekend is still a five-session streak. The run ends at the first session that did not move the same way, and a session that closes exactly level ends it too, because a flat day is neither an up day nor a down day.

The length of a streak and the size of the move it produced are different facts, and reading only the first is the common mistake. Across the companies stocks-llm covers, runs of the same length have been worth anything from about 3% to over 50%: persistence and magnitude are independent. That is why both numbers are quoted together — the count says how many sessions leaned one way, the percentage says how far the price actually travelled over exactly those sessions.

stocks-llm computes streaks nightly from delayed daily-close prices, split-adjusted, and counts backwards from the most recent close. A run is published only once it has been seen to stop — if the run reaches the oldest price we hold without breaking, its true length is unknown and no figure is shown rather than a count that would only be a floor. Streaks describe sessions that have already closed. There is no rule that a run of a given length is "due" to continue or to reverse; a long fall can mean a stock has been sold off indiscriminately or that something is genuinely wrong with the business, and the streak itself cannot tell you which. Nothing here is advice.
