Successful investing requires capital, courage, and judgment\u2014a speculator must possess all three. Good judgment isn&#8217;t simply innate; it must be cultivated to understand the complexities of the financial industry.<\/li>\n\n\n\n<li>When speculating, the path to success lies in studying value. Successful speculators buy or hold securities priced below their true value and avoid buying or selling securities priced far above their true value. Successful investors must also follow this strategy. Some seek long-term returns and should buy undervalued securities rather than those that fully reflect their true value. When undervalued securities adjust to their true value, those seeking capital gains profit. It takes time for prices to adjust to their true value.<\/li>\n\n\n\n<li>Leonard Ayres discovered the relationship between stock prices, dividend yields, and the market. The average return is calculated by dividing the Dow Jones Industrial Average&#8217;s stock price by the total dividends of its components. In bull markets, dividend yields are low, while in bear markets, they are high. Over the past thirty years, only one bull market has failed to push this index above 20 points, and every bear market has driven it below 17 points. Once a market trend is established, a minimum limit for this index can be set based on this fact.<\/li>\n\n\n\n<li>In practice, pyramid financing can never achieve its theoretical maximum, allowing clients to continue to raise margin indefinitely as stock prices rise. Brokerage firms may be happy to allow clients to trade with a 20% margin, but this does not mean that traders are safe from losses within 20%. On the contrary, as soon as the decline of any individual stock threatens 20% of their equity, the brokerage firm will begin to call for margin to protect its own safety.<\/li>\n\n\n\n<li>When the stock market is falling, there are many current stockholders, but fewer when it is rising. If the percentage held by brokerage firms is sufficient to represent the number of shares in margin accounts, it is clear that there are more shares when the market is rising and fewer shares when it is falling. This may be because more and more people view common stocks as long-term investments.<\/li>\n\n\n\n<li>Since brokerage firms began reporting margin balances, there have been four instances where margin balances increased significantly more than stock prices. Each time this occurred, the market plummeted within the following sixty days.<\/li>\n\n\n\n<li>Technical analysis charts, such as line charts, generally fail to provide definitive technical indicators because they are based on hindsight.<\/li>\n\n\n\n<li>Investing is an art form, and interpreting market behavior is more of an art form than a science. Technical factors cannot be reduced to a set of simple rules. Those who study technical analysis typically focus solely on short-term stock price fluctuations. Over the long term, the ability to draw accurate inferences from economic fundamentals can yield substantial profits. Combined with the ability to analyze technical market conditions, even long-term traders can significantly increase their profits.<\/li>\n\n\n\n<li>Short selling minimizes stock market volatility. At the end of a bull market, excited investors can drive stock prices skyrocketing, completely disregarding value. Short selling, however, can help the market regain its composure, expose weaknesses, and provide timely warnings to investors. Conversely, when the market is overly pessimistic, timid investors hold off buying for fear of further declines. In such extreme market conditions, short-covering buying can be a significant force, perhaps even enough to halt the decline.<\/li>\n\n\n\n<li>It&#8217;s difficult for short sellers to profit from long-term short selling because bull markets almost always outlast bear markets. Long-term short sellers have to fight the long-term trend of rising values, and their chances of profit are far lower than those of long-only traders.<\/li>\n\n\n\n<li>Depreciation is perhaps the most important accounting item on the income statement. While other items are more or less beyond the control of senior management, every dollar of depreciation is determined by them. If performance is poor, the depreciation provision can be reduced to improve the balance sheet.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"80\" height=\"114\" src=\"https:\/\/www.granitefirm.com\/blog\/us\/wp-content\/uploads\/sites\/2\/2025\/08\/The-Art-of-Speculation-Custom.jpg\" alt=\"The Art of Speculation\" class=\"wp-image-37509\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Related_articles\"><\/span>Related articles<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2026\/08\/08\/the-art-of-speculation\/\">&#8220;The Art of Speculation&#8221; <\/a><\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2024\/06\/30\/a-random-walk-down-wall-street\/\" target=\"_blank\" rel=\"noreferrer noopener\">&#8220;A Random Walk Down Wall Street&#8221; is a must-read for US stock investors<\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2021\/05\/10\/primer-books-for-investing\/\" target=\"_blank\" rel=\"noreferrer noopener\">Great primer books for Investing in the stock market<\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2021\/06\/05\/one-up-on-wall-street\/\">&#8220;One Up on Wall Street&#8221;, Peter Lynch&#8217;s great book for investing newbie<\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2025\/05\/27\/benjamin-graham-on-value-investing-grahams-bio-book\/\">&#8220;Benjamin Graham on Value Investing&#8221;, Graham&#8217;s bio book<\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2025\/07\/28\/charles-ellis\/\">Charles Ellis and his &#8220;Winning the Loser\u2019s Game&#8221; <\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2021\/07\/investors-should-pay-attention-to-the-annualized-rate-of-return-irr-how-to-calculate\/\" target=\"_blank\" rel=\"noreferrer noopener\">Investors should care annualized rate of return (IRR), calculate with free IRR Calculator<\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2021\/05\/13\/what-information-should-investors-take-notes-why\/\">What information should investors document?<\/a>&#8220;<\/li>\n\n\n\n<li>&#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2021\/07\/10\/sustained-investor\/\">A investor can be sustained or not?
