The 90/10 rule in investing is a comment made by Warren Buffett regarding asset allocation. The rule stipulates investing 90% of one's investment capital toward low-cost stock-based index funds and the remainder 10% to short-term government bonds.
The Rule of 120 (previously known as the Rule of 100) says that subtracting your age from 120 will give you an idea of the weight percentage for equities in your portfolio. The remaining percentage should be in more conservative, fixed-income products like bonds.
The reality is that stocks do have market risk, but even those of you close to retirement or retired should stay invested in stocks to some degree in order to benefit from the upside over time. If you're 65, you could have two decades or more of living ahead of you and you'll want that potential boost.
Exposure to stocks should remain an important part of your allocation target, even in retirement. However, a possible need to access these assets for income in the near term means you are more susceptible to short-term risks.
Treasuries are safe investments because they are backed by the “full faith and credit” of the US federal government. The US government has never defaulted on a debt obligation.

A common asset allocation rule of thumb is the rule of 110. It is a simple way to figure out what percentage of your portfolio should be kept in stocks.

Many novice investors lose money chasing big returns. And that's why Buffett's first rule of investing is “don't lose money”. The thing is, if an investors makes a poor investment decision and the value of that asset — stock — goes down 50%, the investment has to go 100% up to get back to where it started.

With $100,000 you should budget for a retirement income of around $5,000 to $8,000 on top of Social Security, depending on how you have invested your money.

Romantic couples with a large age gap often raise eyebrows. Studies have found partners with more than a ten-year gap in age experience social disapproval.
