算opition vs. stock 啦,
我又琢磨了半天,觉得还是应该买stock.
assumption: option price 20, current stock price 30, 100 shares each.
if sell 100 options at 30, then stock drops to 15, sell 100 stocks at 15,
total proceed: (30-20)*100 + 15 * 100 = 2500
if sell 100 stocks at 30 then stock drops to 15, no options to sell
total proceed: 30 * 100 = 3000
如果股票在20 以上,卖哪个都一样.
如果股票掉到20 以下,还是先卖stock 好.
所以从降低风险的角度来说,还是要先 |
