Tickers Mentioned

Episode Summary

Twenty-day breadth collapsed from 98% to 45% in a single session, flipping the regime defensive across nearly every timeframe. The desk digs into which breakouts have real volume behind them versus empty moves, and flags CLS, MU, and MPWR as the rare names still holding institutional structure amid the flush.

Key Takeaways

20SMA breadth collapsed to 45% from 98%, down 53 points
40SMA breadth slipped to 54.86% from 60.57% yesterday
Bear 4% at 217 dwarfs Bull 4% at 90
Energy leads at 100th percentile, RSPG up 1.18%
Continuation names run on thin RVOL below 1.0

Midday Situation Check

Bearish regime deteriorating fast — 40SMA breadth at 54.86% (down from 60.57% yesterday, -5.7pp), while 20SMA breadth cratered to 45% from 98% (-53pp), a violent one-day flush in short-term participation.

Market Recap — Session So Far

Index snapshot unavailable this session — SPY, QQQ, and IWM all show data unavailable, so we’re reading the tape through breadth and internals instead.

SPY / QQQ / IWM: price and technical levels are unavailable in today’s feed — no SMA20/50/200 or 20-day range to cite, so we lean on breadth for regime read.
Breadth internals: Bull 4% at 90 vs Bear 4% at 217 — decliners more than doubling advancers on the 4% signal, confirming Bearish sentiment on both the 4% and 40SMA reads.
Longer-term signals: Bull 20% at 45 vs Bear 20% at 11 still net-positive, but Bull 9M just 8 vs Bear 9M 35 shows the longer-horizon damage building underneath.

Momentum Watch — Breakout Continuation & SIP

Strongest continuation: FOUR $48.10, +8.5% — the day’s leader on the Continuation scan, though RVOL is light at 0.5, so treat the move with caution on conviction.
New SIP entries: HD $338.13 reported better Q2 results and guidance (sentiment 2), running RVOL 1.52 in RETAIL; ENRD $6.16 flagged a NewProduct catalyst (500 Tesla Semi trucks) in TRANSPORTATION.
Follow-through check: HTFL $44.30, +5.6% is the only continuation name with RVOL at 1.0 — the rest of the top-10 sit at 0.6 or below, signaling thin participation behind these breakouts.

Strategy Check — Continuation, SIP & 20% Study

Continuation holding vs fading: IMUX $16.89, +5.4% (RVOL 0.6) and BBNX $18.24, +3.9% (RVOL 0.5) lead the MEDICAL cohort, but low RVOL across ALNY, AXON, and COST (all 0.6 or under) argues these are drifting, not driving.
SIP movers: WEAV $5.54 popped +2.97% from open on a Francisco acquisition announcement; SLE $3.02 gapped 34.8% on an agreement with an extreme RVOL of 556.54 — a micro-float event, not a tradeable trend.
20% Study confirmation: Institutional momentum names include CLS $340.56 sitting at demand (0.12% away, strength 6.1), MU $1,011.75 between zones with supply just 4.61% overhead, and MPWR $1,415.99 with supply 7.23% up — leaders holding structure despite the breadth flush.

Quick Takes & Wrap-Up

CLS — watch the demand zone at $308.36–$313.83; a hold here keeps the institutional bid intact, a break opens air below.
MU — the $982.21–$992 supply band (4.61% overhead) is the level to clear; rejection there caps the semis bounce.
Overall bias: Defensive — with 20SMA breadth collapsing 53 points to 45% and Bear 4% at 217, this is a risk-off tape; favor Energy (RSPG at 100th percentile, +1.18% today) and be selective, keeping risk tight (FFM, <=2.5%).

Action codes in focus: ABC (Always Be in Control) given the breadth flush, and FFM (Find Free Money, <=2.5% risk) to press only the cleanest setups like CLS at demand while the regime stays hostile.

Welcome to WaveRider mid-day wave, your mid-session market intelligence. Let's dive in. 20-day breath just fell 53 points in a single session. Is this a flush or the start of something bigger? That's the question, isn't it? Okay, so how has the regime shifted since open? It's flipped, straight to defensive. 40-day breath is down to 54.86% from 60.57% yesterday. So a little under six points. Right. Minus 5.7. But that's not the story. 20-day breath cratered to 45% from 98%. Wait, 98 to 45? In one session. That's wild. Short-term participation just evaporated market-wide. And the bull bear 4% confirms it. Bull 4 at 90, bear 4 at 217. So, declineer's more than double the advances. More than double, yeah. Is the longer horizon still holding or? Partly, bull 20 versus bear 20 is still met positive 45 to 11. But here's the thing, bull 9 month is 8, bear 9 month is 35. Oh, so the damage is building underneath? Exactly. Multiple time frames lining up bearish. Okay, so bias is defensive. With breath that thin, what does that do to today's breakouts? Makes them suspect. Look, four leads the continuation names at $48.10 up 8.5%. That's a big move. It is, but R-roll is only 0.5. Huh, so a loud move on no volume. A shout in an empty stadium. HTFL is the only one with real participation. $44.30 up 5.6% R-roll at 1.0. And the rest of the top 10? 0.6 or below every single one. Wow, what about the medical names? Same drift. I am UX at $16.89 up 5.4%, BBNX at $18.24 up 3.9%, but low R-roll there too. So drifting, not driving. You got it. Any new entries worth lagging? A couple. HD came in at $338.13 on a Q2 beat, and this one actually has volume, R-roll 1.52. Oh, finally some conviction. Right. NRD entered at $6.16 on a Tesla semi-order, 500 trucks. Nice catalyst. And then there's SLE, gaped 34.8%. 34% on what volume? R-roll of 556. 500, hold on, are you serious? Dead serious, but it's a micro-float event, a single firework, not a tradable trend. So ignore it? Ignore it, yeah. OK, so if broad breakouts are thin, is anything actually holding structure? This is the part that matters. The 20% study names. C-L-A-S at $340.56, sitting just 0.12% from its demand zone, strength 6.1. So the institutional bid is right there? Right there. MU at $1,11.75 with supply only 4.61% overhead. MPWR at $1,415.99 supply 7.23% up, still holding. See, that's the divergence. Everything's flushing, but these three are standing. Load bearing walls and a building getting torn up around them. I like that. OK, so what changes from the morning plan? Tighten everything. The action code is ABC. Always be in control given the flush. And the level that matters most? Two of them. C-L-A-S demand zone, $38.36 to $313.83, a hold keeps the bid intact, a break opens air below. And MU? Supply band, $982.21 to $992, rejection there caps any semis downs. Any sector actually leading? Energy, RSPG at the 100th percentile, up 1.18% today. So that's your rotation angle. That's the one. And if you're pressing anything, it's the cleanest setup only. CLS at demand, sized at 2.5% risk. Selectivity over exposure. Every time into a tape like this. So here's the takeaway. Breath broke hard. The tape's defensive, but CLS, MU and MPWR are still holding the line. Watch that CLS demand zone. Watch MU supply band. Tighten your risk and stay selective until breath stabilizes. We'll check back at the close. That's all for today's episode of Wave Rider Midday Wave. Your mid-session market intelligence. See you next time.
