Honestly, its the book I wish I had when I was in my teens, or even my 20s. I could have invested my stock boy earnings instead of buying a Fender Stratocaster!
Bought and read the book. Not a bad book, pretty basic but for a beginner would suffice. You are the first person I have seen who has recommended O'Neil's "How to make money in stocks". It's the book I would recommend to any novice investor.
Do you find the advice still applicable to today's markets? That would be pretty cool, after 30+ years...
Absolutely, read the book, it re-in forces and hammers down the absolutely most important principle: do not ever buy stocks that are on a decline no matter how cheap and never short advancing stocks even if they are expensive. No other book teaches this better than this book. And no other behavior in investing and trading has killed more portfolios and trading accounts than the violation of above rule. It sounds all cute and sweet when people buy companies they like but a good stock investment does generally have a zero correlation with a liked company or a company whose product someone may like or use. Zero correlation just meaning no causal relationship. It also talks about market timing, where really the edge is, and it's not in the tops or bottoms ever.
