Warren Buffett had been a net seller of stocks for eight consecutive quarters. The streak has now increased to nine after Berkshire Hathaway disclosed its Q4 holdings. However, Buffett didn't only sell stocks in the latest quarter.

Given the overbought and expensive stock market, these four Warren Buffett favorite dividend stocks look like safe ideas for investors now.
