Hope you&#8217;re well. Wishing you a happy holiday.<\/p>\n\n\n\n<p>I originally planned to write a personal investment perspective inspired by your blog before the new year, but I hesitated due to my observations not being fully developed. However, after you posted the article &#8220;AST SpaceMobile turning every phone into a satellite phone&#8221; on February 16th (readers can click on &#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2026\/02\/16\/ast-spacemobile-satellite\/\">AST SpaceMobile turning every phone into a satellite phone<\/a>&#8221; to read the article you mentioned that was published on my blog), I became more certain of my views.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Counter-Positioning\"><\/span>Counter-Positioning<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In conclusion: To increase the probability of tenfold gains, counter-positioning is a good entry point.<\/p>\n\n\n\n<p>Reasons:<\/p>\n\n\n\n<p>Nature of the Problem:<\/p>\n\n\n\n<p>What stock selection criteria can effectively filter stocks in promising industries, even in the face of competition from existing industry giants, to provide ordinary investors with a high probability of winning tenfold stocks?<\/p>\n\n\n\n<p>Relevant Factors:<\/p>\n\n\n\n<p>Besides the elements and industries provided by Brother Ziyang&#8217;s scattered articles or three books, Dr. Hamilton of Yale University&#8217;s Economics Department\u2026 Hamilton Helmer, in his book <em>7 Powers: The Foundations of Business Strategy<\/em>, outlines a &#8220;market power (or competitive advantage) process&#8221; that suggests a company&#8217;s initial stage should involve &#8220;reverse positioning&#8221; or &#8220;monopolistic resources,&#8221; which is a good starting point. In short, what I&#8217;m trying to say is that innovation (or invention) is indeed important. <\/p>\n\n\n\n<p>However, in an era of highly dynamic competition and cooperation in industries, conversely, investors seeking disruptive innovations in products, business models, brands, and processes\u2014strategies that put incumbents in a difficult position\u2014can be a good way to filter and select ten-bagger stocks. When you mentioned the article &#8220;Why is it difficult for investors to discover Shopify potential early? (2023\/2\/14)&#8221; (readers can click on &#8220;<a href=\"https:\/\/www.granitefirm.com\/blog\/us\/2023\/02\/14\/discover-shopify-early\/\">Why is it difficult for investors to discover Shopify potential early?<\/a>&#8221; to read the post mentioned by the chairman and published on my blog), as you stated in the article, the three-step process for successful investment does indeed have necessary conditions.<\/p>\n\n\n\n<p>I repeatedly read the first step (gathering as much relevant information and facts as possible: slightly researching Shopify&#8217;s products, discovering that it provides a unique ecosystem service different from other competitors) and didn&#8217;t have a deep understanding of it back then, but now it resonates with me greatly, and I&#8217;m surprised to find that I often fall into the second layer of thinking outsourced to the blind spots of financial media.<\/p>\n\n\n\n<p>Returning to AST SpaceMobile, this also fits the counter-positioning pattern. Thanks to the development of AI, investors can more easily summarize massive amounts of information; however, the key is how to judge it. A quick summary by ASTS is as follows:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Strategic dimensions<\/td><td>AST SpaceMobile (Newcomer)<\/td><td>SpaceX Starlink (incumbent)<\/td><\/tr><tr><td>Disruptive business models<\/td><td>&#8220;B2B wholesale model&#8221;: Profit sharing with global telecommunications providers (MNOs). ASTS does not grab telecom customers, but becomes a &#8220;5G feature option&#8221; for telecom operators.<\/td><td>&#8220;B2C vertical integration model&#8221;: Although there is T-Mobile cooperation, its core DNA is &#8220;bypassing the middleman&#8221;, which may ultimately threaten the traffic position of global carriers.<\/td><\/tr><tr><td>The dilemma of the incumbent<\/td><td>&#8220;Embrace allies&#8221;: There is no need to consider the damage to existing customers, because 3 billion carrier users are its ready-made market.<\/td><td>&#8220;Competitive conflict&#8221;: If Starlink wants to imitate ASTS and cooperate with all telecom operators in the world, it must give up its &#8220;exclusivity&#8221; and &#8220;terminal control&#8221;, which will harm its current high-profit home\/business subscription system.<\/td><\/tr><tr><td>Collateral damage<\/td><td>Extremely low: The success of ASTS will increase the ARPU of the carrier, which is an &#8220;incremental subsidy&#8221; for the existing ecosystem.<\/td><td>Extremely high: If Starlink is fully expanded, it will be a &#8220;stock substitution&#8221; for traditional ground-based telecom operators and optical fiber service providers, which will trigger a collective defense of global telecommunications supervision.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Market Powers<\/td><td>AST SpaceMobile<\/td><td>SpaceX (Starlink)<\/td><td>Conclusion<\/td><\/tr><tr><td>Reverse positioning<\/td><td>\u2b50\u2b50\u2b50\u2b50\u2b50<\/td><td>\u2b50<\/td><td>ASTS makes telecom operators allies, not enemies.<\/td><\/tr><tr><td>Patent assets<\/td><td>\u2b50\u2b50\u2b50\u2b50\u2b50<\/td><td>\u2b50\u2b50\u2b50<\/td><td>ASTS has exclusive technology in &#8220;large array antennas&#8221;.<\/td><\/tr><tr><td>Turning costs<\/td><td>\u2b50\u2b50\u2b50\u2b50<\/td><td>\u2b50\u2b50\u2b50<\/td><td>ASTS is embedded in the carrier architecture and is extremely sticky.<\/td><\/tr><tr><td>Economies of scale<\/td><td>\u2b50\u2b50<\/td><td>\u2b50\u2b50\u2b50\u2b50\u2b50<\/td><td>SpaceX has a rocket advantage with the lowest launch cost.<\/td><\/tr><tr><td>Network effects<\/td><td>\u2b50\u2b50\u2b50\u2b50<\/td><td>\u2b50\u2b50\u2b50<\/td><td>ASTS has a stronger network effect in the telecom ecosystem.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>In short, I personally believe that ATS possesses the potential to become a ten-bagger after screening. As for what market power (competitive advantages) ATS SpaceMobile should gradually acquire as the company develops, and whether the CEO&#8217;s capital allocation is appropriate, that&#8217;s another story. Currently, it is indeed overvalued.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Note\"><\/span>Note<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Thank you again for your selfless sharing of many insightful articles and criticisms of investor blind spots.
