Рекомендую обратить в этом тексте вот на какую фразу (это чисто научное размышление):
"This was a 17-sigma (standard-deviation) event"..
We learned that once again this week as Russia invaded Ukraine, sending the MSCI Russia Index down 38% in a single trading day, its largest decline ever.
This was a 17-sigma (standard-deviation) event, which according to statistical forecasting should never have happened even once in the history of the universe. But it did, and given enough time, it will happen again.
2) Ruble in Ruin
The Russian Ruble crashed on the news, hitting new all-time lows. Since its peak in 2008, the Ruble has now lost 73% of its value against the US Dollar.
