注意到20只基因组学/测序股在同一周突破。分不清是真实的板块轮动还是我在匹配噪音
作者观察到基因组学股票因降息而突破，但因成交量低迷质疑其可持续性。
- 利率下降和通缩环境提升了无盈利的基因组学长久期公司的估值。
- 3个月中位数涨幅达33%的广泛价格上涨表明这是真实的板块轮动。
- 突破缺乏成交量确认，相对成交量大多在1倍或更低。
- 这可能只是模式匹配的噪音或悄然上涨，一旦大盘转向极易反转。
So I run a screen across 2800 nasdaq names, returns over a few horizons, distance from 52w highs, relative volume, dispersion, that kind of stuff. mostly to keep myself honest on the macro instead of trading off headlines. been doing it daily for a while now.
this week one thing stuck out and I've been chewing on it for a couple days so figured I'd just put it here and see if anyone's seeing the same thing or can tell me why I'm wrong.
there's a clump of genomics / DNA sequencing / diagnostics names that are all going to new highs at basically the same time. not one or two flyers, more like 20-25 of them. Twist (TWST) is up 100%+ over 3 months, Maravai 98%, NeoGenomics +77, Veracyte 79, then CareDx, Natera, Guardant, and even Illumina which has been dead money for literally years is up 40. the median name in that bucket is +33% over 3mo against roughly +4% for the whole nasdaq. so it's not just two rockets dragging the average up, the actual group is moving together.
why now, and this is just my read so push back: rates have been coming down and commodities are getting wrecked, gold/oil/silver all down double digits on the month. that's a disinflation tape. and the thing about most of these genomics companies is they make no money, the whole value is terminal-value way out in the future. so when the discount rate drops they're exactly the names that rip. long-duration equity basically. that part kind of makes sense to me.
here's what's actually bugging me though, and the real reason I'm posting. almost none of it has volume behind it. price is making new highs but relative volume is sitting around 1x, sometimes under. my screen literally tags most of them "needs volume." only a couple (Maravai, Natera) have real volume confirming the move. so I honestly can't tell if I'm early, in before the crowd, which is where you want to be, or if this is just a quiet drift higher that folds the second the tape turns.
I've got a small starter in TWST and I'm watching NEO, so that's my bias, take it for what it's worth.
couple things I'm genuinely trying to figure out:
does a breakout with no volume mean anything to you, or do you just wait for the volume even if it means giving up the first leg? I go back and forth on this constantly.
and if anyone actually follows this space, is there a fundamental catalyst here I'm missing (some approval cycle, funding thing, M&A chatter?) or is it really just the rate move pulling the whole group up at once?
not advice, I'm a macro guy poking at a sector I don't know that well, which is half the reason I'm asking.
Fwiw-I own some Pharma that’ve been going up the last couple days. Not as dramatically as the stocks you describe. My assumption is that people are rotating out of the chip and ai stocks.
I think your rate-sensitive basket explanation is plausible, but the weak volume matters because it can mean the move is being driven more by positioning and duration repricing than by fresh conviction on the businesses. If I were trading it, I would treat that as a reason to start smaller and wait for either volume confirmation or an actual catalyst instead of assuming the whole group suddenly has better fundamentals.
Yes, agree. My positions here are really small, just seeing if this leads anywhere. And agree on volume too, it doesnt confirm. Other thing is the HY vs IG credit. Usually, these bets work well when junk credit is also outperforming. But again it is not confirming either
