Hi Everybody…
Herb Greenberg | On the Street, also known as Herb on the Street, is a culmination of my 50 years reporting on, writing about and researching stocks, companies, the markets and virtually any and every industry.
I spent much of my decades-long career as a financial journalist and also co-founded two short-biased research firms. I even spent a year working at a risk arbitrage firm. You can read my bio on LinkedIn. I get exhausted just looking at it.
This is what I do. This is what I love. If there’s such a thing as true passion, professionally, this is it. It’s in my DNA to fly red flags, but I like flying a few green ones, too... while poking holes in conventional wisdom and going out of my way not to follow the herd.
Most of all, I like using facts and figures to tell stories, with a goal of not boring you in the process.
There are lots research reports out there; not all of them are fun to read.
I figure if I have fun writing it, you will enjoy reading it... and hopefully either making or avoid losing money along the way.
If you have any questions, I’ll try to answer them in my FAQs below. Otherwise feel free to reach out at herb@herbgreenberg.com.
FAQs
Before we get started: I’m building a community of serious investors, not a “trial-and-cancel” service. Because my research provides immediate access to proprietary archives, all sales are final – no refunds or free trials. If you’re unsure, stick to the free tier or become a monthly subscriber until you’re ready to commit.
The Strategy: Red Flags & Research
Who should subscribe to you? This newsletter isn’t for the casual “meme stock” trader or someone looking for a “get rich quick” tip or trade. It is for:
Risk-Averse Investors: People who believe that the best way to grow wealth is to first ensure you don’t lose it on companies with hidden structural or financial flaws.
Active Short-Sellers: Traders looking for fundamental catalysts and “short alpha” backed by my research.
Institutional Pros & Analysts: Professionals who need a skeptical second opinion that isn’t influenced by investment banking relationships or “pay-to-play” research models.
The Naturally Skeptical: If you find yourself asking “This looks too good to be true” you’re at the right place.
Long Investors: If you’re long-biased, think of this as insurance – or reason to re-underwrite or re-review your position – if I flag one of your companies.
What is a “Red Flag Alert”? Red Flag Alerts highlight stocks to avoid, focusing on hidden structural, financial, or behavioral risks. While designed to help investors sidestep blow-ups, short-sellers often use these reports to identify fundamental short opportunities.
What does do I get with a Red Flag Alerts subscription: My Red Flag Alerts, full archives and regular topical commentary.
How does this differ from “Herb on the Street”? Herb on the Street is my signature brand for commentary and market observations. These posts are typically available to all readers.
I notice you also have “Special Situations”. What is that? That’s where I publish the occasional under-the-radar or out-of-favor long idea.
How do you source your ideas? I pull from a variety of sources: short-sellers, quantitative data, and a private network of investors and collaborators. I am incredibly selective. I reject far more ideas than I actually do, relying on my decades of experience to decide what is worth your time.
Do you provide price targets or “Buy/Sell” ratings? No. My work is based on observations and interpretations of facts and filings; it is not investment advice. I provide the information; you and your advisor make the decisions.
Is this suitable for beginners? Only if they’re serious. This work helps investors understand who may be on the other side of their trades—and why. Many readers say it sharpens their skeptical instincts while cutting through market noise in an easy-to-consume, often entertaining format.
Subscription & Logistics
How often do you publish? I don’t write to hit a quota—that leads to noise, not value. However, I am “wired to write.” You can expect a post (free or paid) at least once a week, approximately 46 weeks a year. In reality, I usually publish more frequently than that.
How often do you publish new Red Flag Alerts? I only publish an Alert when I have a compelling, deeply researched case. My internal target is 8 to 15 per year. My recent track record reflects this discipline:
Total Alerts (May 2023 – Dec 2025): 48
2025 Alerts: 15
Do you update your previous Red Flag ideas? I update them when it is warranted, but I do not promise a specific follow-up schedule or anchor my life to earnings season. My archives serve as a living record of how these ideas play out.
What do I get after I subscribe to your annual tier? You will get immediate access to my full archive and full access to all Red Flag Alerts and updates or “subscriber-only” reports I write.
Why is the monthly price so high compared to the annual rate? The pricing is intentional. It is designed to discourage...” try: “Monthly pricing is higher to discourage one-off subscribers cherry-picking single reports. I’m building a community, not a drive-through.
Do you offer group rates? Yes. You can find details on my Group Subscription Page.
Red Flag Alerts Pro
What is your invitation-only Red Flag Alerts Pro tier? Red Flag Alerts Pro is specifically tailored for institutional investors, family offices, and professional investors who require a deeper level of engagement and access.
Why invitation-only? I’m highly selective about the Pro community to ensure the “fit” is right for everyone involved. Most members come from hedge funds and family offices, but also include sophisticated individual investors. I maintain a strict “no-jerks” policy.
Do you accept soft dollars? Yes.
Refund Policy
Do you offer refunds? No. I don’t offer trials, either. Previews to my premium work as well as my free reports should provide a good indication of what subscribers can expect.
Engagement & Disclosure
Do you make buy/sell recommendations? No.
Do you put valuations on stocks? No.
Do you offer investment advice? No.
Do you offer group calls? Yes! I will be starting an interactive Office Hours for paid subscribers every 4–6 weeks. This will be held in a group setting via video.
Are you invested in the stocks you write about? I do not short stocks directly or through options. If I ever have a long or any position in a company I mention, it will be clearly disclosed.
Can I send you ideas? Absolutely. I welcome tips and ideas from readers. You can reach out via my private email or herb@herbgreenberg.com.
Bottom Line
Think of my newsletter as a skeptical second opinion designed to help you avoid bad stocks, bad narratives, and bad capital allocation decisions—before they cost you money.
