緩衝ETF在基金經理人認定的股市高點藉選擇權放空以鎖定下跌風險，
這有幾個問題：
1. 不一定放空到最高點，可能少賺很多。
2. 需付出7%選擇權成本，回檔超過7%才划得來
我認為我的方法績效會比較好：
在GDP高點減碼，最多賣1/3，
如此既可避掉大盤風險，
賣得太早的損失也不大，
同時讓手中好股繼續成長
BlackRock launches stock ETF with 100% downside hedge
(Reuters) -BlackRock has launched a 'buffer' exchange-traded fund that seeks to offer a 100% downside hedge to risk-shy investors looking to tap the equity markets, the world's largest asset manager said on Monday.
So-called buffer or risk-managed ETFs help maximize returns from an asset for investors and simultaneously provide downside protection over a specific period.
