Reddit reviews The Little Book of Common Sense Investing: The Only Way to Guarantee Your Fair Share of Stock Market Returns (Little Books. Big Profits)

• The Little Book of Common Sense Investing - Jack Bogle. He explain why just buy and hold a low cost index fund (like SPY) is the way to go.
  
• The Intelligent Investor - Benjamin Graham. The Bible of Stock Picking. Unfortunately, less than 1% can beat the market long term doing that.
  
• The Single Best Investment - Lowell Miller. Good if you thing is income.
  
• Dual Momentum Investing - Gary Antonnacci. A really good improvement of Jack Bogle's thesis of investing only in index funds.

I found Bogle's Little Book of Common Sense Investing very helpful.

I was in your position a couple weeks ago as a beginner, and here are some of the resources I found useful to learning the basics:

• Read all of the basics on the r/personalfinance sidebar, it has some pretty good advice.
  
  
• Read all of the sidebar frequently asked questions on the /r/investing sidebar.
  
  
• Read If You Can by William J Bernstein. Its a short pamphlet with some additional assigned reading found inside that will fit what you’re looking for. (I've personally read the first two 'homework' assignments and they were very good.)
  
  
• Read The Richest Man in Babylon by George S Clason.
  
  
• Read The Little Book on Common Sense Investing by John C Bogle. It's a very well written short book highlighting the power of Index Funds. It's very clearly biased (he was the one who basically invented them and also founded Vanguard), but is absolutely worth the read.
  
  
• Read The Intelligent Investor by Benjamin Graham. This can apparently be likened to the Bible of Value Investing. Certainly much longer than all the previous reading, but also worth taking the time to read and learn. I found the additionally commentary chapters by Jason Zweig very helpful.
  
  Im currently reading A Random Walk Down Wallstreet, and it’s definitely very valuable and worth reading. Highly recommend.
  Hopefully this helps and at least gives a starting point.
  
  Good luck!

The book which had the biggest influence on me and changed my view on Investing was from John Bogle, Father of index funds.

This is the one and only one book on index investing you require ;-).
