🤖 The gut microbiome becomes a real therapeutic platform
Friedberg's science corner off the Cell paper on artificial sweeteners: sequencing a gut biome collapsed from ~$1,000 to ~$5, which has triggered an explosion of microbiome research, and the gut-brain axis means disease and neurological conditions can be altered by changing the biome. Fecal transplants are showing curative signal in MS, Parkinson's, IBS and colitis (Chamath), while single-strain probiotics do not inoculate and do not work — the winners are whole-ecosystem approaches: live consortia, FMT-derived pills, gut-derived small molecules turned into drugs, and feedstock modulation.

⚖ Why this verdict
fully deterministic — evaluate.py replays this from daily closes; nothing below is editable or hand-set
- Window: 2022-08-26 → 2023-08-26 — first mention + 12-month horizon, then the window locks.
- The call: ▲ LONG MCRB (primary play). MCRB fell 35.1% over the window → direction-adjusted R = -35.1% (the call lost money).
- Benchmark: holding SPY over the same window returned +10.3% → α = -35.1 − (+10.3) = -45.4% — what this call made or lost against just owning the index. This is the number the verdict uses.
- Rule fired:
· HIT — R ≥ +10% AND α ≥ +5· PARTIAL — R ≥ +5% OR α ≥ 0▶ MISS — everything else
- Credit: supporters of a MISS earn 0 each, opposers the inverse — this feeds the scoreboard weights. supported: Chamath, Friedberg

| ▲ LONG | MCRB | stock | PRIMARY | Seres Therapeutics — the listed live-microbiome therapeutic, an oral fecal-derived pill, exactly the 'little pill with the fecal stuff in it' Friedberg describes |
| ▲ LONG | ILMN | stock | adjacent | the enabler Friedberg names explicitly — the sequencing cost curve that made routine gut-biome reads possible |
| ▲ LONG | XBI | etf | adjacent | the small-cap biotech cohort where the 'ton of startups and billions invested' in microbiome eventually lists |

“So guys, there's a known principle that's really deeply studied now in neurology, in neuroscience, called the gut-brain axis, that you can actually profoundly affect disease and the condition of the brain and neuro conditions by changing the gut biome.”

SUPPORT
“But we are finding now that you can take feces from healthy individuals that have good gut biome and good bacterial counts, and if you put it, inject it into people that are suffering from a bunch of different diseases, it actually is looking like it's curative. So Parkinson's, MS, IBS, colitis.”
