Kristjan Kullamägi is a Swedish trader who goes by Qullamaggie on social media. He is one of the most transparent successful traders of his generation — he has livestreamed his trading, posted detailed breakdowns of his best and worst trades, and given multiple long-form interviews explaining his exact methodology.
He reportedly turned an initial $30,000 into over $100 million over roughly a decade, with several years producing 1,000%+ returns. He traded primarily US growth stocks — highly volatile, high-momentum names during the 2017–2021 growth bull market. His approach is documented in his free PDFs published on his blog.
Kullamägi's edge is concentration and size. Where most traders diversify to manage risk, he focuses on a small number of high-conviction ideas and scales into them aggressively when they're working. His biggest trades are often 30–100%+ position sizes in a single name.
The stocks he targets share a set of characteristics:
Kullamägi's favourite setup is the episodic pivot — a stock that has a specific event (earnings beat, FDA approval, contract win) that fundamentally changes its trajectory. The event creates a gap or a sharp single-day move that marks a new chapter for the stock.
He enters the day of or shortly after the event, as the stock is making its initial large move. He wants to get in early in what he believes will be a sustained multi-month trend. The risk is defined by the low of the episodic day — if the stock falls back below the level where the event started, the thesis is invalidated and he exits.
His second major setup is the high and tight flag — a stock that has made a sharp vertical move (often 50–100% in a short period) and then consolidates in a very tight range for 2–4 weeks before breaking out again. This pattern is a sign that the initial move was driven by institutional buying and the consolidation is simply digestion, not distribution.
The entry is on the breakout from the tight consolidation. Volume should pick up on the breakout day. The stop is below the low of the consolidation.
Like all successful momentum traders, Kullamägi never averages down. If a position moves against him, he cuts it. But unlike more conservative traders, he has no problem averaging up into winners — adding to positions that are already moving in his favour.
His position-sizing approach: he starts with a pilot position (perhaps 10–15% of portfolio) on the initial breakout. If the stock proves itself — moves up and holds above the breakout level — he adds more. He may ultimately have 50–100% of his portfolio in a single name if the conviction is very high and the stock is acting correctly.
His maximum loss per trade is typically 5–10% from his entry — tight enough that concentration doesn't cause permanent capital impairment if he's wrong.
Kullamägi's most explosive growth came during the 2017–2020 period when cloud software stocks were in a historic bull market. Names like SHOP (Shopify), TTD (The Trade Desk), and CRWD (CrowdStrike) made multi-hundred-percent moves over 12–24 months. He was documented owning these during their big moves.
He also had significant trades in 2020 during the COVID recovery — names like ZM (Zoom) and various biotech stocks that moved explosively during the pandemic-driven tech boom.
