Every few months the market reminds everyone it can convulse without warning. An algo fund implodes overnight. A bank everyone trusted trades below $5. A “can’t-lose” theme turns out to be a bubble. The names change; the story rarely does. Once you have seen enough blow-ups, you stop being surprised by them and start noticing the pattern they share.
The yen-carry lesson: leverage plus averaging down
A while back an automated-algo outfit blew up averaging down into the Japanese yen — at high leverage — all the way down. That sentence holds the two ingredients behind most spectacular failures: leverage, which turns a survivable loss into a fatal one, and averaging down, which adds to a position precisely because it is losing. Together they guarantee that your largest position is your worst idea at the worst possible time. A system that sizes by risk and cuts losers cannot make that mistake — it is not undisciplined enough to.
The Credit Suisse lesson: headlines and single-name risk
When Credit Suisse slid below $5 on fears it might go under, it spooked the whole market — and it had been a terrible holding since 2007. Two lessons fall out. First, single-stock conviction is how people lose the most: a “blue chip” can bleed for fifteen years. Second, the scary headline is usually late — by the time the fear is on every screen, the move is largely done. Reacting to it is trading the news, not an edge.
The bubble lesson: greed is the fuel
Behind every bubble is the same hidden force: greed that inflates prices past any reason, pulling in rich and poor alike, right up until it doesn’t. You do not need to predict the top to survive a bubble; you need rules that take you out when the trend actually breaks, and sizing that makes being wrong an inconvenience rather than a catastrophe. Trying to call the exact top is just a different flavor of the overconfidence that inflated the bubble.
The ‘Crazy Ivan’ lesson: craters are survivable
I use the phrase “Crazy Ivan” for the sudden, violent craters that appear out of nowhere. In the moment they feel like the end of the world. But a system with defined risk on every position treats a crater as just another data point — mechanically working the plan instead of reacting. The edge is not a prediction that the crater is coming; it is that the rules already decided what to do, so the crater cannot trigger a panic decision. Back-tested and hypothetical results have inherent limitations; past performance is not indicative of future results.
The quieter blow-up: sitting on your hands
Not every disaster is dramatic. The slow one is fear-driven paralysis — getting scared out of a system and sitting on the sidelines “until things calm down.” Markets rarely ring a bell when it is safe again, and the best runs often begin in the ugliest conditions. Sidelining feels safe, but it carries a real, compounding cost: the trades you skip are frequently the ones that pay. A good system answers “should I be in?” for you, every day, without flinching.
The pattern — and the antidote
Strip away the headlines and every blow-up rhymes: too much leverage, adding to losers, no predefined exit, position sizes that cannot survive a normal bad streak, and decisions made in an emotional state. The antidote is not a better forecast. It is mechanical rules that define the entry, the exit, and the size before the storm — so when the next algo implodes or the next bank wobbles, you are already positioned to survive it, and occasionally to profit from it.
This is really risk management wearing a news headline — see why psychology, not prediction, is the bottleneck and how to size each trade so a bad streak cannot ruin you.
