The ABC of Stock Speculation (1903)
Samuel Armstrong Nelson was an American financial writer of the early 20th century. His book The ABC of Stock Speculation (1903) was among the first to treat stock market speculation as a legitimate science, including price patterns and supply-demand cycles — and he was the first to coin the term 'Dow Theory' in print, based on Charles Dow's editorials.
🧠 Core Philosophy
Stock prices move in cycles that can be identified through technical patterns and signs of overextension or exhaustion — not just trend, but where within the cycle price currently sits.
❓ Key Question
"Is the price overextended, or is there still room to move?"
