The VIX surged 21.5% Friday, but Bitcoin’s steady weekend trading and historical patterns suggest Wall Street’s fear may ease Monday. The VIX fell on 25 of 32 Mondays after Friday jumps of at least 20% since January 1990, with a typical decline of 4.5%, according to CoinDesk. Bitcoin held above $80,000, while Volmex’s BVIV was little changed near 40%. Traders also positioned for the VIX to close above 23 by the third week of November. The historical pattern is no guarantee: the VIX rose on Monday in seven cases and remains below 20.
