NEW YORK (TheStreet) -- Shares of Ulta Salon Cosmetics & Fragrances (ULTA) - Get Ulta Beauty Inc Report are shooting higher by roughly 15% after beating on top and bottom line estimates. 

On CNBC's "Cramer's Mad Dash" segment, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, also pointed out that same-store sales were higher in the recent quarter, while the company guided for next quarter's same-store sales to also be higher. 

After becoming bearish on the company after several disappointing earnings results, Cramer changed his tune, saying, "I'm a believer," now that the company has a "renewed mission" and its strategic plan is paying off. 

Turning quickly to Five Below (FIVE) - Get Five Below, Inc. Report, he called shares "undervalued" at $35 and also said management at RadioShack (RSH) should just admit the company's recent earnings results were bad. 

He also noted that B. Riley & Company lowered its price target on RadioShack to $0. Needless to say, that's a sell rating.

While wrapping things up, Cramer looked to the analysts' commentary on shares of Micron (MU) - Get Micron Technology, Inc. (MU) Report. Bank of America upgraded the stock to buy from sell, while Credit Suisse also issued a buy rating and raised its price target from $30 to an astounding $50. 

Cramer said that according to the analyst comments from Credit Suisse, it's not only tight supply that's keeping prices of DRAM high, but also strong demand. 

Co-host David Faber added that a lot of hedge funds are invested in Micron.
