There's investing and there's trading, and there are different kinds of trading. Trading for Dummies focuses on position trading, which is less risky than day trading. It is written for readers who are &#34;not completely new to the world of investing in stocks&#34; and who are &#34;familiar with the stock market and its basic language.&#34; The authors recommend that readers who are completely new to investing and trading read a basic book on investing in stocks before reading Trading for Dummies.That said, Trading for Dummies should help anyone who has a basic understanding of investing in the stock market get a basic understanding of the world of trading, including options. Some &#34;for Dummies&#34; books are better than others, and this one is, IMO, one of the better ones. I've been an investor in stocks, etc., since the early 80's and today I'm also a conservative position trader who dabbles in options. Over the decades I've read a number of books on investing and trading, including options, but I avoid books that I find overly technical and/or math heavy (and thus too hard for me to follow), and I find Trading for Dummies very reader-friendly and easy to follow (as &#34;for Dummies&#34; books are meant to be). So I would recommend it to anyone who has a basic familiarity with investing in stocks and who either wants to get started in low- to moderate-risk trading or who just wants to get a sense of what such trading involves. Part of its reader-friendliness is that it's easy to skip around in, and it is well-indexed and like all &#34;for Dummies&#34; books, it has a comprehensive, index-like table of contents (I guesstimate over 400 entries), which makes it easy to quickly find any section of the book (almost like using hypertext).
