The stock gains have come despite signs earlier this year of problems for Florida-based Tupperware Brands Corp.
Tupperware's stock on Thursday was also among the most watched tickers on retail-investor-focused Stocktwits.com, with an "extremely bullish" sentiment score.
The sharp, unexplained gains echo those seen in Bed Bath & Beyond (BBBYQ.PK) before it filed for bankruptcy and other "meme" stocks known for their sudden popularity with retail investors.
Also like other "meme" shares, Tupperware's stock is highly shorted.
Even with the recent gains, Tupperware's stock is down about 30% for the year to date.
