Two years of independent investing, told honestly. Each study walks through a real position I took: the thesis going in, what the charts showed, what actually happened, and the lesson it left behind. Several of these trades, the Deckers one especially, became the real-world evidence behind my research paper on how institutional trading psychologically disadvantages the average investor. The wins and the mistakes both made the cut.
My research paper, "The Psychological Impact of Institutional Trading on the Average Investor," examines how the structural advantages of financial institutions create doubt, confusion, and disadvantage for ordinary investors. It is the intellectual backbone of this entire site: the case studies are its evidence, and the Learn section exists to close the gap it documents.
Whether through day-to-day transactions or long-term investments, investors buy monetary assets in pursuit of profit. Many believe their timing is strategic, yet the sizable purchases and sales by large financial institutions can produce confusion and unrealized loss for the average investor. This paper details how institutional influence and actions psychologically affect average investors by creating a doubtful and uncertain trading environment. By analyzing institutional advantages and incorporating case studies with existing market data, it affirms that financial institutions exert a measurable psychological impact on average investors.
Price targets as misplaced confidence. Using my own documented Deckers trade, the paper shows how analyst price targets from reputable institutions (Jefferies raising its target before earnings, UBS raising it again after a 20.51% drop) can anchor retail decisions while carrying no obligation to be right, producing confusion precisely when investors feel most reassured.
High-frequency trading and its infrastructure. The paper traces how colocation services place institutional servers next to exchange data centers, how Bloomberg Terminals (roughly $28,000 to $32,000 per year) deliver information faster than retail investors can receive it, and how research links rising HFT activity to increased stock herding among retail traders across ten international exchanges.
Momentum ignition and herd behavior. It examines how rapid order placement can manufacture price trends that noise traders follow, how such activity is difficult to regulate because it mimics ordinary trading, and how FOMO and herd mentality leave retail investors buying the very moves institutions profit from.
The Palantir case. The paper analyzes Palantir's run after its September 2024 S&P 500 inclusion and its 38.71% fall in spring 2025 on defense budget cuts and a $1.1B CEO share sale, showing how trend-following retail buyers absorbed the shock that better-researched institutions could treat as opportunity.
Institutional advantages in capital, information speed, and research depth create a structural and psychological divide. The most practical defense available to the average investor is independent research: understanding what a company actually earns and why, rather than outsourcing conviction to price targets, trends, or the crowd. That conclusion is the reason this site teaches the way it does.
The trades that informed this paper are documented honestly in the section, and the analytical process behind them is laid out in the . The paper was written at BASIS Independent Silicon Valley and draws on 22 cited sources spanning academic journals, SEC literature, and Congressional Research Service reports.

Options are contracts that give you the right, but not the obligation, to buy or sell a stock at a set price before a set date. They are powerful and genuinely useful, but they are also where many beginners lose money fast. This is a plain-language tour of how they work, what drives their price, and why they cut both ways.

Two years of trading across fifty-plus names taught me that a method matters more than any single call. This page lays out how I actually research, the tools I trade with, the signals I read, and the rules that keep me disciplined. The honest answers, including the mistakes that shaped them.
I started before the market opened. By 6:30 most mornings I was already up, checking what had moved overnight while the rest of the house was still asleep. It wasn't discipline at first. I was just curious, and the curiosity didn't really switch off.
My first trade was Newmont, the gold miner.
I bought it because gold felt safe and the name was one I recognized, which is about the least sophisticated reason there is. It drifted sideways for weeks while I checked the price far too often, and I eventually sold close to where I got in, having learned nothing about the company and everything about myself. That was the lesson: recognizing a name is not the same as understanding a business, and boredom is not a reason to trade.
I didn't know much going in, and it showed. But it got me hooked on the question underneath all of investing, which is figuring out why something is worth what it costs, and being willing to be wrong about it. The losses taught me more than the wins. A win can just be luck, and it's easy to take credit for it; a loss makes you go back and find the actual mistake.
Over two years, that's what changed the most, not the picks, but the process around them. I started writing my reasoning down publicly and ended up with more than a hundred articles, mostly because putting an argument in writing makes its weak spots obvious. The early mornings are still there. They just mean something different now: less about catching the next big mover, more about trusting a method I've actually tested.
I use three tools deliberately, each for what it does best, rather than relying on any single one.
Separating where I research from where I execute keeps the analysis honest, the chart work happens before the trade, not as a justification after it.
I evaluate an idea in a deliberate order, fundamentals first to decide whether a company is worth owning, then technicals to decide when. The sequence matters: a strong chart on a weak business is a trap, and a great business at the wrong moment is dead money.
First I ask what the company actually does and how it makes money, whether revenue and margins are growing, and how its valuation compares to peers in the same sector rather than the market as a whole. Only once a name passes that filter do I move to the chart to time an entry.
In practice, the three things I check first are revenue growth, profit margins and the trend in them, and how the valuation compares to direct competitors rather than the whole market. The fastest way to make me walk away, no matter how clean the chart looks, is a business I can't explain simply: if I can't say in a sentence how the company makes money and why that will keep working, I don't own it.
On TradingView I lean on a focused set of indicators rather than cluttering the chart. Each answers a different question.
I lean most on the multi-timeframe RSI, because a signal that only shows up on one timeframe has burned me before. Reading it across the daily and weekly together filters out a lot of noise, and I treat any single indicator as a reason to look closer, never as a reason to act on its own.
Process protects you from yourself. The rules below exist precisely for the moments when conviction or fear would otherwise take over.
I size positions so that no single trade can do serious damage to the whole portfolio, scaling risk down sharply for the more volatile, speculative names. I decide my exit before I enter, both the level that proves me wrong and the one that takes profit, so the decision is made with a clear head rather than mid-move.
Concretely, I keep any single position small enough that a bad outcome is an inconvenience, not a disaster, and I cut that size down sharply for the speculative, high-volatility names where I'm really just taking a small shot. I set the level that would prove me wrong before I buy, so the exit is a decision I made calmly in advance rather than one I'm forced into during a sell-off.
This section goes beyond beginner material, it's here for readers who already understand the basics and want to see how options positioning can move stocks. If you're just starting out, the Learn tab is the place to begin.
The Greeks, briefly. An option's delta is how much its price moves when the stock moves one dollar. Gamma is the rate at which that delta itself changes, essentially the acceleration of an option's sensitivity. A high-gamma option reacts faster and faster as the stock moves.
Why gamma becomes a market signal. The dealers who sell options must hedge by buying and selling the underlying stock. When dealers are long gamma, their hedging works against price moves, selling into rallies, buying into dips, which dampens volatility and tends to pin a stock near heavily-traded strikes. When dealers are short gamma, hedging amplifies moves instead, buying into strength and selling into weakness, which can turn an ordinary move into a violent one.
Calls, puts, and gamma walls. Heavy call activity clustered at a strike can create a "gamma wall" that behaves like a magnet or ceiling for the price; concentrated put activity can do the same on the downside. Watching where that positioning sits is one way traders anticipate whether a stock is likely to stay pinned or break out.
Options involve substantial risk and are not suitable for most beginners. This is an explanation of mechanics, not a strategy recommendation.
The biggest lesson is that temperament beats prediction. My worst results came from abandoning the rules above in the heat of a move, and my best from sitting still when the process said to. Indicators and analysis matter, but they're only as good as the discipline to actually follow them.
The most expensive mistakes I made all came from the same place: acting out of impatience or fear instead of following the plan I'd already written down. The rule that came out of it is simple and the hardest one to keep: decide what you'll do before the moment arrives, then actually do it. Two years in, I'm convinced that's worth more than any single good call.
