This crypto startup firm, Uprise, lost 99% of its client funds while shorting Luna during its price crash. Luna crashed 99.98% within 1 week from Thursday, 5 May 2022  to the following Thursday, 12 May 2022. Just 1 week ago, Luna's market capitalization was USD28 billion. 1 week later, this USD28b crashed by 99.98%. This is the fastest and biggest price crash in crypto history. A short-seller who shorted Luna should be making huge sums of money in quick time. Yet, Uprise lost 99% shorting Luna.

How can this happen?

The answer can be found in the hourly price chart of Luna. Luna surged violently by 708% within an hour from 13 May 2022 10 am-11 am Singapore time. I guess this is the hour that pretty much killed Uprise. Even if Uprise survived this hour, there were several other hourly intervals when Luna surged above 100% and even 300%.

Short-selling in a strong bear market is dangerous even if you get the direction right because bear markets have very violent rallies. The most a short-seller can earn is 100% because the price cannot fall below zero. However, he can lose several 100% because there is no price ceiling. It is quite easy to be killed quickly if what you shorted surged more than 700% within an hour.

There is little time to react if the security you shorted surged multiples of 100% within an hour. This can even happen when you are sleeping if it trades round the clock like crypto or futures. This is less of an issue for machine algorithms than for humans. Since Upsize runs on machine algorithms, it should be fast enough to exit but I guess the position size was too large and there wasn't enough exit liquidity.

Uprise employs Artificial Intelligence trading strategies. These strategies are developed based on historical data. Machine learning strategies will fail for rare events because there is not enough data to train the algorithms to cope with these rare events.

Here are some risk-management lessons that I extract from this fiasco.

Lesson 1) Watch position size relative to liquidity. If position size is too large and liquidity is not deep enough to exit fast, the violent price reversal will kill you, especially in a bear mark rally.

Lesson 2) Algorithms based on Artificial Intelligence need to recognize when the market enters into rare situations where the algorithms are not trained to operate in. In these situations, either stop trading or reduce position size drastically. Leverage should be cut to 0.

Lesson 3) Try to avoid trades with the risk of losing more than 100%. Putting 10% of capital into a single position is reasonable and not reckless position sizing but even that moderate size with zero leverage can cause serious injuries if the position goes against you by 700% within an hour. Short-selling stocks and trading in securities with built-in leverage such as options and futures carry the risk of losing more than 100%. So, be acutely aware of these risks when you attend courses that teach these strategies to achieve financial freedom as some trainers may downplay the risks to sell the courses.

Global financial markets have slipped into bear markets today. It is tempting to try out short-selling in this bearish environment. However, unless you have good reason to believe you have an edge in short-selling, it is best to avoid it.
