I never buy a stock even in a bull market, if it doesn’t act as it ought to act in that kind of market. I have sometimes bought a stock during an undoubted bull market and found out that other stocks in the same group were not acting bullishly and I have sold out my stock. Why? _Experience tells me that it is not wise to buck against what I may call the manifest group-tendency._ I cannot expect to play certainties only. I must reckon on probabilities--and anticipate them. An old broker once said to me: “If I am walking along a railroad track and I see a train coming toward me at sixty miles an hour, do I keep on walking on the ties? Friend, I sidestep. And I don’t even pat myself on the back for being so wise and prudent.” Last year, after the general bull movement was well under way, I noticed that one stock in a certain group was not going with the rest of the group, though the group with that one exception was going with the rest of the market. I was long a very fair amount of Blackwood Motors. Everybody knew that the company was doing a very big business. The price was rising from one to three points a day and the public was coming in more and more. This naturally centered attention on the group and all the various motor stocks began to go up. One of them, however, persistently held back and that was Chester. It lagged behind the others so that it was not long before it made people talk. The low price of Chester and its apathy was contrasted with the strength and activity in Blackwood and other motor stocks and the public logically enough listened to the touts and tipsters and wise-acres and began to buy Chester on the theory that it must presently move up with the rest of the group. Instead of going on this moderate public buying, Chester actually declined. Now, it would have been no job to put it up in that bull market, considering that Blackwood, a stock of the same group, was one of the sensational leaders of the general advance and we were hearing nothing but the wonderful improvement in the demand for automobiles of all kinds and the record output. It was thus plain that the inside clique in Chester were not doing any of the things that inside cliques invariably do in a bull market. For this failure to do the usual thing there might be two reasons. Perhaps the insiders did not put it up because they wished to accumulate more stock before advancing the price. But this was an untenable theory if you analysed the volume and character of the trading in Chester. The other reason was that they did not put it up because they were afraid of getting stock if they tried to. When the men who ought to want a stock don’t want it, why should I want it? I figured that no matter how prosperous other automobile companies might be, it was a cinch to sell Chester short. _Experiences had taught me to beware of buying a stock that refuses to follow the group-leader._
