HOKU - up 22% today

A caller wanted to know if the buying in Hoku Scientific (HOKU:Nasdaq - commentary - research - Cramer's Take), which is up about 65% the past two days, had been overdone. The newly public company was the subject of two bullish research reports Thursday, and Cramer also spoke positively of the stock on his "Mad Money" TV show. Cramer said the stock had "moved too much," and he would wait for a pullback before buying. However, he added, the company, which has research and development agreements with Nissan, Samsung and the U.S. Navy, is making money and is "for real." But it's not the same stock at $10 as it was at $5, said Cramer.
