Turbo — leveraged tracker that dies on a barrier

Turbos (also called "mini-futures" or "knock-out certificates") are the structured product retail traders fall in love with. They give you 5×–20× leverage on the underlying for the price of a coffee, with a built-in stop-loss. Until the stop-loss fires.

The promise

Spot is €100. The issuer offers a Long Turbo with these features:

• Strike (financing level): €90.
• Knock-out barrier: €92 (slightly above the strike).
• Price today: ~€10 (= spot − strike, plus a tiny financing spread).

The trade behaves like this:

• Spot rallies to €110: turbo worth ~€20. You doubled your money. The stock moved 10%; you made 100%. That's the leverage.
• Spot drops to €95: turbo worth ~€5. Same 10% move, same 5x leverage in the loss direction.
• Spot ever touches €92 (the barrier): turbo dies. Settles at ~€0. Even if the stock bounces back to €100 the next day, the position is closed. You lose the entire premium.

How it's built

A Long Turbo is essentially a down-and-out callwith a strike equal to the financing level (€90) and a barrier slightly above it (€92). Replication: imagine you bought €100 of stock with €10 of your own money and €90 borrowed at the risk-free rate. You're long stock × 1, short the loan × 1. The total position is worth (S − 90) right now, which is €10 — and moves €1-for-€1 with the stock.

That's 10x leverage on your €10 stake. Beautiful. Now the catch: if S drops to €92, the issuer auto-liquidates the position to avoid going below the strike. You take the loss; the issuer doesn't.

Why it's cheap

Compared to a vanilla call, a Turbo:

• Has almost no time value. The strike is so far in the money (well below spot) that intrinsic value dominates. Theta is essentially the financing carry — usually small.
• Has almost no vega. The barrier is right next to the strike, so vol changes don't move the price much.
• Has the knock-out risk— which is what you've sold to fund the cheapness.

It's pure directional leverage with a tail risk. If you're wrong on direction or even right but timing is off (touch + bounce), you lose everything.

When does it work?

When you have a strong directional view with a clear timeframe and you accept that a small adverse move kills the position. Day-traders, swing-traders, momentum-following retail flow.

It does not work as a long-term position. The closer you are to the barrier, the larger the absolute leverage but the higher the knock-out probability. Most retail Turbo holders lose, partly because volatility is underestimated, partly because timing is hard.
