My latest MoneySense Retired Money column looks at a must-read new book on Retirement as well as two related books on DIY stock-investing. You can read the full column by clicking on the highlighted headline: Who you gonna trust: Barry Ritholtz or Jim Cramer?

The must read and main focus of the MoneySense column is William Bengen’s A Richer Retirement: Supercharging the 4% Rule to Spend More and Enjoy More. If that sounds familiar it should: Bengen’s original book on the 4% Rule is considered the bible of retirement, with his famous “SAFEMAX” guideline of 4% a year being an annual amount of withdrawals that should be “safe” for retirees to continue for a full 30 years, even after inflation. The original book,  titled Conserving Client Portfolios During Retirement, was first published in 2006.

Never mind that even Bengen considers 4.7% be a more universal SAFEMAX. The original book was aimed at financial advisors and professionals while the new one ostensibly is aimed at retail investors and retirees. I say ostensibly because I was a little disappointed with it and found the plethora of complicated charts and tables a bit much for lay investors. Still, there’s a lot of common sense there: Inflation is big long-term threat to retirees as are bear markets. Withdrawing too much from portfolios can be disastrous if you are unfortunate enough to retire just as a bear market hits and/or inflation starts to bite.

On the other hand, sticking with the old 4% rule or even the smaller amounts of 3% or even 2% advocated by some cautious souls, could result in you withdrawing less than you really need to enjoy retirement, although the tax department and any heirs might commend your caution and frugality.

How to make money in any market

While it’s rare for me to buy new hardcover books because I receive so many “free” review copies of financial books, I actually did buy A Richer Retirement as soon as it was available on Amazon. Plus, unusually, I also bought two other brand new books on the related topic of investing and stock-picking.

One was Jim Cramer’s How to make money in any market, by the sometimes revered but often maligned host of  CNBC shows Mad Money and Squawk on the Street. It’s fashionable for some financial journalists who believe in efficient markets and indexing to diss Cramer but I am not in that crowd. In fact, Cramer recommends that newcomers to investing put the first US$10,000 into an S&P500 index fund or ETF.

However, for seasoned investors and even retirees, Cramer suggests putting half a portfolio in index funds and the other half in individual stocks. Where we part company is his recommendation that the bucket of stocks be restricted to just five names, which would mean 10% in each. For my money, that’s way too concentrated and risky, even though he often brags about how he is often accosted by Nvidia Millionaires who tell him they bought that stock as soon as he announced on air that he had renamed his dog Nvidia.

How NOT to invest

Finally, regulars to this site may already have read Michael Wiener’s review of Barry Ritholtz’s How NOT to invest, which appeared here in this blog a few weeks after appearing on his Michael James on Money blog.

To be sure, those who are fond of disparaging Jim Cramer might quip that should have been the title of his own book, seeing as there are actually ETFs out there that try to profit by shorting Cramer’s picks. As of this writing, my copy has arrived but I have not yet finished reading it, as it’s a bit longer than the other two.

But based on the book blurbs and Michael’s review, I have no doubt it will be worth reading, whether for younger investors or seasoned ones and/or retirees.

Finally, while I only just received my review copy, I note that David Chilton is publishing a new edition of his classic financial novel, The Wealthy Barber, which any young person just starting to invest should acquire.  I look forward to revisiting it.
