I didn't start StockCram because I knew a lot about investing.

I started it because I didn't — and I couldn't find anywhere to learn without getting lost.

My first stock

It happened in college, on a couch, on a friend's phone.

He'd been talking about this one company for weeks — something he kept calling “cutting through technology.” He'd zoom in on a chart, trace his finger across a jump, and say:

“If we'd put ten grand in right there, we'd have this.”

Some number that made us both lean in. We each bought one or two shares. About $20 apiece. Not life-changing — just enough to feel like we'd stepped into something.

Before I tapped buy, he gave me the rule I still think about:

Then he mentioned options:

“Way more complicated. Way higher risk. Not really for everyone.”

And he moved on to the next chart. That line stuck with me more than any of the charts did.

Why I built StockCram

For years after college, investing hovered in the background. I'd buy a few shares of things I'd heard of. Read articles I didn't really understand. Every so often I'd get curious about what my friend had meant by “options,” go look it up, and give up within a few minutes.

Every resource had the same problem: it assumed the previous lesson for me. “Beginner” content skipped what a stock actually is. “Intermediate” content assumed you already knew the Greeks. “Advanced” content was usually marketing for a trading platform.

Eventually I sat down and worked through it myself — call options, puts, premiums, the actual math. It took effort, but nothing was the wall I'd been told it was.

The problem wasn't finance. It was how finance was being explained.

I come from a technical background — systems, infrastructure, DevOps. When I hit a confusing system at work, my reflex is to write documentation for it, and to structure it so the next person doesn't have to retrace my steps. That's what StockCram is: the documentation I wish had existed when I was the one stuck.

I've been paying attention to markets since I was a kid — the kind of person who reads the economics section of the news for fun. I started putting real money in during 2019. The years since have been about working through what makes markets actually move, how options really behave under pressure, and — the part that matters most to me — how beginners actually learn.

Mistakes I made early

Not “lost my shirt” mistakes. Small, honest things that slow beginners down. A few I hope to save you from:

• I thought diversification meant owning different tickers. It can also mean different types of holdings — stocks vs bonds, US vs international, large vs small companies. Owning 20 tech stocks isn't really diversified.
• I bought things I couldn't explain. If I couldn't describe the company's business in one sentence, I had no way to judge whether the price was reasonable. Now I don't buy anything I can't explain to a friend.
• I thought brokerage apps were designed to help me. They're designed to keep me using them. The nudging-toward-more-trading thing is a product choice, not an accident.
• I bought an option with more money than I could afford to lose. I was convinced it was going up. It dropped a little the next day — and because the position was sized way past my real risk tolerance, that small paper loss panicked me into selling to stop the bleeding. The stock went on to run up hard; if I'd held, the contract would have been worth roughly six times what I paid. The lesson isn't “trust your gut and hold” — that's not a rule, that's hindsight. The lesson was my friend's rule from college, the one I hadn't actually followed: only put in money you don't need. At that size, I was never going to be calm enough to watch a normal move. The position size itself made the mistake inevitable.
• I checked my portfolio every day. Nothing about a well-chosen long-term holding changes day to day. The habit cost me sleep; it never made me money.

What I learned

A few things that changed how I read finance — and how I teach it:

• Jargon is usually gatekeeping. Most finance terms describe simple ideas. Anyone who won't stop to define their words is either confused themselves or benefits from your confusion.
• Boring is usually better. Most sustainable wealth-building looks boring from the outside: consistent contributions, broad index funds, long time horizons. Excitement tends to come at a cost.
• The internet rewards urgency; investing rewards patience. A good information diet for a long-term investor looks nothing like what social media serves.
• “Nobody knows” is a complete sentence. Nobody reliably knows where the market will be next month. Plans that assume otherwise are usually selling you something.

What I focus on, and what I don't do

The work so far

StockCram is growing. Everything is free to read, no account required. The numbers as of today:

Every piece is reviewed for accuracy before it goes live, and major claims link back to sources like the SEC, FINRA, and the Federal Reserve.

Find me elsewhere

I publish under the same name across platforms. If something here was useful, you'll find more of the same voice in these places:

• Substack — longer posts on what I'm learning, behind-the-scenes of building StockCram, and the honest parts.
• X (@stockcram) — short notes, links, and the occasional chart.
• A personal site at seansha.com is in progress — I'll link when it's ready.

Where to start

If any of this sounds like where you are — or where you've been — the best starting point depends on what you need today. Pick the door that fits.
