证券自营业务的实质是经营风险
选择了一个行业,自然会关心这个行业的发展。现在大数据火,什么只能投顾之类的,很可能是以后的趋势,自己也就颇为关系自营业务未来怎么样。
仔细想来,国内自营以前主要就是炒股票,和散户博弈,从这个角度看,证券自营业务确实没什么必要,就如同股票市场里面的散户一样,都是落后的生产力。
但是如果看的更深入一点,证券自营实际上是市场上的风险承担者,作为市场上的避险需求的对手方。正如同我们做的期权做市。
实际上,我以为作为做市商,和高频交易公司不一样,高频交易公司存在的意义就是赚钱,而做市商是承担风险。当然所有做市商都希望能和高频交易公司一样,大量交易,稳定盈利,但是这种日终零头寸的业务模式,并不是经营风险。
对于大机构来说,他核心的优势是体量大,稳定,可以承担市场的波动,因此,他可以作为经营风险,经营风险是他的核心优势,在市场恐慌时,他买入风险资产,而在市场乐观时,将风险资产转租。
从这个角度看,大机构的期权做市核心就是卖出,再细一点,就是以机构可以承受的现实风险,外加经营成本和利润需求之后,以这个价格接受风险。
