Downswing

Also known as: losing streak, dry spell

An extended losing stretch driven by negative variance, not necessarily by bad play.

A downswing is a prolonged period where you lose money or run below expectation. The hard part is that a normal downswing and a genuine skill problem look identical from inside one — both feel awful.

The statistics are sobering. Because results spread as \(\sigma\sqrt{N}\) (see variance), a clear winner will have multi-buy-in downswings as a matter of course. A 5 bb/100 cash winner with \(\sigma=100\) bb/100 routinely sees 15–25 buy-in downswings over a career; MTT players regularly endure 100+ tournament cashless stretches while still being long-term profitable.

What to actually do:

The correct response to a downswing is almost always: keep playing your A-game at an appropriate stake, or stop and reset — never to gamble bigger.

Example

An MTT reg with a long-term 25% ROI plays 200 events and is down 8 buy-ins. Is the edge gone? Not necessarily: MTT ROI variance is so high that an 8-buy-in trough over 200 events sits comfortably within one standard deviation for a true 25%-ROI player. The sample is simply too small to indict the win rate.
