Since this specifically mentions pink sheet stocks I would say it must apply to pink sheet stocks.
Might be best to read before making such an all encompassing statement.
"Trading Volume Formula. After the one-year holding period, the number of shares you may sell during any three-month period can't exceed the greater of 1% of the outstanding shares of the same class being sold, or if the class is listed on a stock exchange or quoted on Nasdaq, the greater of 1% or the average reported weekly trading volume during the four weeks preceding the filing a notice of the sale on Form 144. Over-the-counter stocks, including those quoted on the OTC Bulletin Board and the Pink Sheets, can only be sold using the 1% measurement."
