币界网报道:GreekLive analyst Adam released a daily market brief on July 4, pointing out that the overall market sentiment was neutral and cautious. Traders generally believe that the current market is in a narrow consolidation phase, and the implied volatility (IV) is significantly downward. The community has reached a consensus that the positive vega strategy is not performing well, and in the current low volatility environment, the negative vega strategy has a higher cost-effectiveness. The positive vega strategy refers to constructing an overall positive vega option portfolio to profit from the increase in implied volatility, while the negative vega strategy is the opposite.
