BIIB

The S&P 500 ($745.76) is above its 10-day average ($739.38), so the market-trend check passes for every stock today, BIIB included. It flips market-wide if the index closes below $739.38.

BIIB's 50-day average has risen to $195.16, up from $189.68 10 sessions ago, so the long-term trend check passes. It would flip if that average stopped rising over its 10-session window.

BIIB closed at $209.74, 0.9% above its 9-day average ($207.77) — short-term momentum is holding, so this check passes. It flips on a close below $207.77.

BIIB has 0 consecutive up-closes into today — under the limit of 2, so it isn't overextended and this check passes. It flips after a second straight green close.

No high-volume gap-down consistent with an earnings miss has appeared in BIIB's last 30 sessions, so this check passes. It would flip if such a gap-down showed up inside that window.

BIIB has outpaced the S&P 500 by 12.6 percentage points over the last 20 sessions, so the relative-strength check passes. It flips if BIIB starts lagging the index over that window.

A stop under the recent swing low ($200.19) sits 4.6% below BIIB's price — inside the 2–8% band, so the risk check passes. It flips if that distance drops under 2% or widens past 8%.

The stop sits 1.4× the average daily range (ATR) from price, clearing the 1-ATR minimum, so this check passes — the stop isn't buried inside normal noise. It flips if that room tightens inside 1× ATR.
