有个人叫Richard Smitten，
他跑去访谈杰西李佛摩的儿子，再整理坊间有关李佛摩的书，出了一本
“Jesse Livermore: The World's Greatest Stock Trader”
中间有一小段在讲杰西李佛摩对“主力”的看法
我找不到中文译本，所以贴上原文跟小弟自己的随便翻译，给你参考一下：
==========
Livermore also languished under the cloud of being the Great
Bear of Wall Street. He had been blamed as one of the main causes
of the crash of 1929. But he found this ridiculous, because he
believed that no one person or group could ever change the overall
direction of the market or even drive a stock down for a sustained
period of time. He knew that it was ultimately the sales and
profits of a stock, the financial backbone of a company, that won
out in the end, even though there could be a bumpy ride in the
journey. Nevertheless, people still blamed him, sometimes yelling
at him in public.
李佛摩对“华尔街最大空头”这个称号感到很无力，
他被怪罪成造成1929的原凶之一。但他认为这很可笑，因为他相信，
没有任何人或群体能够持续一段时间地掼压市场，
他知道最后，股票的营收、营利，跟公司的基本面会胜出，即使一路上可能有许多颠颇。
然而，人们仍然怪他，有时还在公共场所吼他
“Companies that make money consistently rise consistently,”
Livermore told all who would listen.
For the public, the nonprofessional stock players, there was
always the famous gray "they" in the market. "They" were raiding Steel
today. "They" were behind General Motors all week, pushing it up.
"They" had a full-fledged bear raid going on with Standard Oil. "They"
were distributing stock right now because "they" knew the market
was finished. "They" were led by that bastard Livermore and his bastard
friends.
“持续赚钱的公司，就会持续上涨”李佛摩说。听的进去的就会听。
对大众来说，对那些非专业的玩家来说，市场上总是有个“他们”。
“他们”今天偷袭钢铁。“他们”这礼拜都在拉“通用汽车”。
“他们”准备好要掼杀“标准石油”。
“他们”正在重新布局股票，因为“他们”知道行情要结束了。
“他们”被像杰西李佛摩那样的有钱混蛋们领导著。
The public believed there was a club, headed by a powerful person
or group, that ran the market. The club supposedly consisted
of people like Livermore, James Keene, John “Bet-a-Million”
Gates, Bernard Baruch, William Durant, Arthur Cutten, and the
Fischer brothers. These people were believed to simply manipulate
the market as they desired, so the small trader was always the
sucker.
大众总是认为有一个团体，由有权势的个人的个人或团体主导著，这些人在控制市场。
这个团体由杰西李佛摩、...(当代有名作手)...等人组成。
这个团体被相信能够随心所欲地操纵市场，所以一般小散户只是当输家。
==========
结论就是，那个年代的人们也一直相信，有一群“主力”在控制市场
但那个年代最有资格被称作“主力”的杰西李佛摩，反而认为，
没有人能控ﾨ謋奕鶠A没有人能够持续跟基本面对作…
※ 引述《mopa (不要留下遗憾)》之铭言：
: 有观察过几档的股票
: 确实有主力券商的存在
: 已经吃了几千张的筹码
: 后来股价的确是涨了
: 但却不见该券商的卖出讯号
: 是该券商还没到获利满足点吗？
: 还是说其实已经默默在出货了？
: 将股票汇拨到名下的其他证券户
: 达成A券商买B券商卖 出货的目的
: 有请主力出来说明一下
