Read why Tupperware shares rose by 56% 

Tupperware shares, the agitated food storage container company, have surged around threefold in the last week.

The company’s shares grew by 56% on Thursday, pushing gains for the last five trading sessions to nearly 350%.

Tupperware shares at record high, but how: 

The 77-year-old firm warned in April that it could go bust unless it quickly presented new financing.

In recent years, Tupperware has been trying to move itself to entice younger consumers but has yet to stop a slide in its sales.

“There is some optimism that a turnaround may be in progress and an investor has been found to help the company,” Neil Saunders, managing director of retail at the GlobalData consultancy, said to the BBC. “However, there is no evidence of this being the case, so any optimism is based on hope rather than certainty,” he continued.

Despite the rise in recent days, Tupperware’s share price is still down by around 30% since the beginning of this year. Tupperware waited to respond to the press for comment. 

Some critics have likened the actions in Tupperware’s share price to other embattled companies, like cinema chain AMC, usually referred to as a so-called “meme stock”.

Trading in meme shares is usually highly hypothetical and flammable due to their popularity amongst retail investors who frequently swap tips online.

Unlike meme stocks, Tupperware stocks have been highly shorted, which means several investors are betting that the shares will drop in value.

Significant hedge funds had bet billions of dollars in these years that shares such as AMC would slip. However, if the share price increases, the investors betting on the cost falling can lose cash.

Earlier this week, AMC stocks increased after a court blocked the company’s plans to pay some of its debts.
