All this was so evident from the first that little or no manipulation for the rise was needed. That was the reason why the preliminary work was so much less than in other bull markets. And not only was the war-bride boom more naturally developed than all others but it proved unprecedentedly profitable for the general public. That is, the stock-market winnings during 1915 were more widely distributed than in any other boom in the history of Wall Street. That the public did not turn all their paper profits into good hard cash or that they did not long keep what profits they actually took was merely history repeating itself. Nowhere does history indulge in repetitions so often or so uniformly as in Wall Street. When you read contemporary accounts of booms or panics the one thing that strikes you most forcibly is how little either stock speculation or stock speculators to-day differ from yesterday. The game does not change and neither does human nature. I went along with the rise in 1916. I was as bullish as the next man, but of course I kept my eyes open. I knew, as everybody did, that there must be an end, and I was on the watch for warning signals. I wasn’t particularly interested in guessing from which quarter the tip would come and so I didn’t stare at just one spot. I was not, and I never have felt that I was, wedded indissolubly to one or the other side of the market. That a bull market has added to my bank account or a bear market has been particularly generous I do not consider sufficient reason for sticking to the bull or the bear side after I receive the get-out warning. _A man does not swear eternal allegiance to either the bull or the bear side. His concern lies with being right._ _And there is another thing to remember, and that is that a market does not culminate in one grand blaze of glory. Neither does it end with a sudden reversal of form. A market can and does often cease to be a bull market long before prices generally begin to break._ My long expected warning came to me when I noticed that, one after another, _those stocks which had been the leaders of the market reacted several points from the top and--for the first time in many months--did not come back_. Their race evidently was run, and that clearly necessitated a change in my trading tactics. It was simple enough. In a bull market the trend of prices, of course, is decidedly and definitely upward. Therefore whenever a stock goes against the general trend you are justified in assuming that there is something wrong with that particular stock. It is enough for the experienced trader to perceive that something is wrong. He must not expect the tape to become a lecturer. His job is to listen for it to say “Get out!” and not wait for it to submit a legal brief for approval.
