Breakout on Contracting Volume
XYZ has traded between 42.00 and 48.00 for eleven weeks. The 50-day SMA is flattening near 45.10 and the 200-day SMA sits at 44.80. On Tuesday XYZ closes at 49.60, above the range top, on 1.4 million shares against a 50-day average of 2.6 million. The sector index rises 0.8% that day, and two sector peers break out on above-average volume. RSI(14) is 64, up from 55 a week earlier. On Wednesday XYZ closes at 48.90, still above the range but below Tuesday's close, on 1.1 million shares. A trader bought at 49.10 on Tuesday's close and now asks whether the breakout is valid, what would confirm or negate it over the next few sessions, and where the trade is wrong.
1. Assess whether the breakout is valid on the evidence given. Refer explicitly to volume, the close, and relative strength.

Short answer: unconfirmed, not invalid.
- A range breakout is validated by expansion of volume, because that signals demand broad enough to absorb supply at the range top. Tuesday's 1.4M is about 54% of the 2.6M average: volume contracted as price left the range. That is the opposite of classic confirmation and raises the probability that the move is a liquidity vacuum rather than accumulation.
- The close above 48.00 is necessary but not sufficient. Wednesday's 48.90 still holds above the range, keeping the breakout technically alive, but it gives back most of Tuesday's gain on lighter volume. That is a stall, not a rejection.
- Relative strength is a partial offset. The sector up 0.8% and two peers breaking out on above-average volume means the move is not purely idiosyncratic; it may be early sector rotation. Peer confirmation cannot substitute for the stock's own volume, though.
Weighing these, the breakout has a below-average prior probability of follow-through. It is not a short signal; it is a "do not add" signal until evidence improves.
2. What specific evidence over the next three to five sessions would confirm or negate the breakout? Give observable thresholds.

Confirmation:
- A close above 49.60 on volume at least equal to the 2.6M 50-day average, ideally 1.5x it.
- A pullback that holds 48.00 on volume below roughly 1.5M, showing supply has dried up.
- RSI(14) holding above 55-60 while price stays above the range.
- Continued peer and sector strength.
Negation:
- A close back inside the range, below 48.00.
- Expanding volume on the decline (above 2.6M), which turns the breakout into a bull trap.
- RSI falling below 50.
- Peers reversing.
The key asymmetry is that a valid breakout should not close back below the range top. One close below 48.00 is a warning; two consecutive closes below 48.00 on rising volume is negation. Time also matters: the longer price holds above 48.00, the more the 11-week range becomes a base rather than a ceiling.
3. The trader entered at 49.10. Define invalidation, a risk budget, and how to handle a false breakout.
Read the worked answer
Invalidation should be defined by structure, not by a fixed dollar loss. The range top at 48.00 is the line; a close below 47.80 (a small buffer for noise) means the breakout failed. That is about 1.30 points, or 2.6% from 49.10. With a 0.5% per-trade risk budget, position size = (0.005 x equity) / 0.026. If price returns to the middle of the range near 45.00, an unstopped loss would be about 8%, so the stop must be honored rather than widened.
A false breakout often retests the opposite side of the range. Do not average down. If stopped out and price later reclaims 49.60 on strong volume, re-entry is justified because the setup has changed. Trimming half on the first sign of failure keeps the decision reversible and reduces the cost of being wrong.
