What's better than momentum? Mo' momentum.

Let's take a closer look at five of this past week's biggest scorchers.

Parlux was last week's biggest gainer, soaring when Perfumania agreed to buy out the rival fragrance company now that CEO Ilia Lekach has stepped down. Parlux investors will receive $4 in cash and 0.2 shares of Perfurmania for every share of Parlux that they currently own.

An analyst reiterated his "speculative buy" rating on MoSys after the memory specialist raised money by selling off dozens of its patents.

Investors cheered Endeavor's endeavor as the energy company is acquiring ConocoPhillips' interest in a few Central North Sea oil fields in a $330 million transaction that will boost its profile.

RAM Energy Resources continues to tack on gains after a recapitalization announced the week before. The sale of oil and natural gas acreage, as well as a $550 million stake acquired by an industry veteran, have combined to give the company brighter prospects.

Finally we have Arctic Cat proving that it's one cool cat. The maker of snowmobiles and ATVs announced that it will buy back the 33% stake in the company owned by Suzuki Motor at a healthy discount.
