mm想请教一下信息安全这个板块,你对这个板块的分析和预测如何?请指点。
我对长期投资还是不太明白,真的是将股票放在那里不管不问吗? 对于止损而言,长期的又该有如何的对策呢?
多谢啦!

关于信息安全可以展开很多,简单写一下
在世界经济论坛每年出版的报告里,从2012年起,网络攻击已经成为发生概率最高的五大全球性风险。在刚刚结束的达沃斯经济论坛上发布的2016年全球风险报告中透露,对全球140个经济体的企业领袖调查表示,大多数受访的美国企业高管最担忧网络风险和攻击行为。这个信息在过去几年完全真实反映出来,无论是收入,就业率,就业面和需求,我个人体会是整个IT行业最热门的分支,而企业的重视程度越来越大。这个行业过去几年有很多整合和并购,这些整合和并购本身也代表了正面的预期和大资金的支持。另外,我想说的是,美国三大支柱,金融,科技,军事是不能倒的。而这三大支柱现在全部建立在信息数字化的基础上,that's why 美国企业高管最担忧的就是网络风险。
长期投资,无论是巴非特那种,还是我之前说的p/e买指数,还是长线投资,对普通人都很难做到的。不然就不会有基金公司这种行业了。不谈巴非特和长线投资,如果仅仅是我前面提到的那种方式,如果真能等到p/e买入价,那不需要考虑止损问题(不是说买了不会跌,只是说不需要担心),只有卖点问题。
顺便贴一下巴非特给股东信里讲到的5个rules,并不是要听巴非特的,而是对照下看自己是哪种类型的投资者(其实很多人并不适应巴非特这一类型的):
You don't need to be an expert in order to achieve satisfactory investment returns. But if you aren't, you must recognize your limitations and follow a course certain to work reasonably well. Keep things simple and don't swing for the fences. When promised quick profits, respond with a quick "no."
Focus on the future productivity of the asset you are considering. If you don't feel comfortable making a rough estimate of the asset's future earnings, just forget it and move on. No one has the ability to evaluate every investment possibility. But omniscience isn't necessary; you only need to understand the actions you undertake.
If you instead focus on the prospective price change of a contemplated purchase, you are speculating. There is nothing improper about that. I know, however, that I am unable to speculate successfully, and I am skeptical of those who claim sustained success at doing so. Half of all coin-flippers will win their first toss; none of those winners has an expectation of profit if he continues to play the game. And the fact that a given asset has appreciated in the recent past is never a reason to buy it.
With my two small investments, I thought only of what the properties would produce and cared not at all about their daily valuations. Games are won by players who focus on the playing field -- not by those whose eyes are glued to the scoreboard. If you can enjoy Saturdays and Sundays without looking at stock prices, give it a try on weekdays.
Forming macro opinions or listening to the macro or market predictions of others is a waste of time. Indeed, it is dangerous because it may blur your vision of the facts that are truly important. (When I hear TV commentators glibly opine on what the market will do next, I am reminded of Mickey Mantle's scathing comment: "You don't know how easy this game is until you get into that broadcasting booth.")
