Killing the Kite: Why I Retired a Strategy in One Day
Every trader has a strategy they love too much. On July 1, Jim's flow-momentum system — the Kite — took a large loss. By the end of the day it was gone from every portfolio. Here's why that decision is the most bullish thing on this site.
From great to destructive
The Kite was a tactical system built around short-dated options flow. It had a genuinely strong run — good enough to earn an allocation alongside Jim's core income structures. Then the character of its performance changed, and changed fast.
Note what he didn't say. He didn't say the strategy was unlucky. He didn't say it needed one more tweak. He identified that its behavior had fundamentally shifted — and treated that shift as the signal.
The decision rule
What separates this from a routine stop-loss is that Jim didn't pull the Kite because he proved it was broken. He pulled it because he could no longer prove it was working:
That's the professional's asymmetry. A retail trader demands proof a strategy is dead before quitting it — and pays for the proof in drawdown. Jim inverted the burden: the strategy has to keep earning its allocation, every week, or it's out.
Keep what's working
The same day he killed the Kite, Jim kept his iron condors and strangles fully deployed — because their record justified it. In his words, he hasn't lost on condors or strangles yet. (The "yet" is doing real work there. That's a trader who expects to be wrong eventually and sizes for it.)
This is portfolio management as triage: cut the bleeding component, keep the producing components, and never let loyalty to a system override its P&L. He even scheduled the post-mortem — review at end of quarter, with the door open to rebuilding the Kite's detection layer with better anomaly logic rather than resurrecting it as-was.
The takeaway
- Strategies are employees, not family. They work for the portfolio. When they stop producing, they're let go.
- The burden of proof belongs on the strategy. "I can't prove it still works" is sufficient grounds to pull it.
- Publishing losses is the credential. Anyone can post winners. The trade record only means something when the Kite's ending is in it.
