關於XIV的計數, Google一下可得, 不作贅述。這裏談談XIV是不是可以穩賺?
滄海將260周可用數據收集一處。為簡單(懶人), 僅以周收盤價為準。按對稱性原則,如買進信號為x%, 則賣出信號為(1-x)%。以下是六對買賣信值:
Buy Percentile | VIX | Sell Percentile | VIX |
95% | 30.2 | 5% | 12.1 |
90% | 24.3 | 10% | 12.4 |
85% | 21.1 | 15% | 12.8 |
80% | 19.5 | 20% | 13.1 |
75% | 18.0 | 25% | 13.5 |
70% | 17.6 | 30% | 13.9 |
買入:VIX初次進入某買進信值(為簡單見, 使用周收盤價, 下同),且無開倉;
賣出:VIX初次進入某賣出信值, 且有開倉。
以下是260周的理論交易小結:
Buy Percentile | VIX | Sell Percentile | VIX | Buy total | Sell total | P&L | P&L% | # Occurances |
95% | 30.2 | 5% | 12.1 | (11.71) | 23.22 | 11.51 | 98.3% | 1 |
90% | 24.3 | 10% | 12.4 | (11.74) | 23.22 | 11.48 | 97.8% | 1 |
85% | 21.1 | 15% | 12.8 | (43.60) | 61.56 | 17.96 | 41.2% | 2 |
80% | 19.5 | 20% | 13.1 | (75.72) | 94.02 | 18.30 | 24.2% | 3 |
75% | 18.0 | 25% | 13.5 | (136.58) | 160.21 | 23.63 | 17.3% | 6 |
70% | 17.6 | 30% | 13.9 | (169.50) | 190.73 | 21.23 | 12.5% | 7 |
可見XIV本身對於SPX並無先天優勢。賺錢還是因人而已。
滄海概不薦股, YMYD
