The home goods retailer saw buying spree in its counter extending on Tuesday as the stock surged 75% to $28.04. More than 160 million shares were traded, which triggered a trading halt. According to data from Bloomberg, the stock was the most actively traded counter. Call options volumes betted on the stock to trade above $45 by the end of the week, while those with money could look at $80 by mid-January. According to Bloomberg data, the stock derivative was the most active among the derivatives segment. The stock has surged despite the downgrading of home goods companies by at least their Wall Street bankers. Two of them even advised the investors to sell the meme stock in the current frenzy. Unrealistic Valuations Susan Anderson of B Riley Securities have cut her recommendation from neutral to sell. She called the retailer's valuation of $2.2 billion unrealistic. Justin Kleber at investment banking company Baird downgraded the ratings of the shares last week before the stock surge. He warned the share's risk/reward ratio looked unattractive and the company was burning cash. Despite the negative outlook on the stock, the surge continued as retail traders and investors pumped in $99 million in the stock since July 26, according to data platform Vanda. The net inflow on Monday was a record $46 million when the shares jumped 24% to close at an all-time high since April.
