(Street Life is a regular feature that profiles what's playing in the stock market.)

Act I: Seaweed skirmish

* The Player: Lululemon Athletica (TSX:LLL)

* Action: Down 29 per cent or $15.13 in a month (from $53 Oct. 19)

* Recent Price: $37.87

* 52-Week High/Low: $58.77/26.40 With the popularity of natural products such as mud in the spa and ylang ylang in shampoo, why not seaweed in clothes?

Yoga clothing retailer Lululemon has been promoting the benefits of VitaSea, the company's new line of clothing that Lululemon says contains seaweed fibres.

Promo material for the clothes claims the seaweed "releases marine amino acids, minerals and vitamins into the skin upon contact with moisture."

But stock of Vancouver's Lululemon has been on a rollercoaster ride since The New York Times printed a story disputing the company's claims about the VitaSea line.

Lab results from a test commissioned by the Times could neither prove nor disprove the existence of seaweed in the clothing.

In accordance with a recent ruling from Canada's Competition Bureau, Lululemon has agreed to remove all labels alleging health benefits from seaweed.

Act II: Triple threat

The Player: TriStar Oil & Gas (TSX:TOG) Action: Up four per cent or $0.35 in a week (from $10 Nov. 12) Recent Price: $10.35 52-Week High/Low: $10.90/6 Good things come in threes, and gains in the share price of Calgary's TriStar Oil & Gas are testament to the adage.

The Calgary exploration company recently announced the acquisition (by amalgamation) of the private company Kinwest Corp. for $92.5 million.

As part of the deal, TriStar will issue eight million common shares to Kinwest shareholders. Closing is expected in January 2008.

TriStar also announced the $11-million purchase of "complementary assets" from an unrelated third party, expected to be completed by yearend.

Assets acquired by TriStar in the two deals are primarily in TriStar's southeast Saskatchewan core area, and have a combined production of more than 1,150 boe/d, with 80 per cent in light oil.

TriStar is also upping its 2008 guidance to 16,250 boe/d average daily production and an exit rate of 16,750 boe/d (from a previously announced 15,350 boe/d average and 16,000 exit rate).

Act III: Drilling Dud

The Player: CMQ Resources (TSXV:CMQ) Action: Down 77 per cent or $0.23 in one day on news Recent Price: $0.07 52-Week High/Low: $0.50/0.05 In times of soaring energy prices and frequent news of resource finds, it can be easy to forget drilling is never a sure thing.

But Calgary's CMQ Resources announced that of the 11 holes drilled in Nevada in the company's 2007 drilling program, the best gold assay received was 7.78 ppm and was at a depth at which gold in such concentrations is unlikely to be commercial.

So CMQ is giving up drilling in the area and will explore the possibility of a sale or joint venture of one or both of its properties (with no assurances such a deal will even be available).

When CMQ releases its Q3 2007 financial statements, all or substantially all of CMQ's investment in its resource properties will likely be written off and CMQ will have limited remaining cash.

CMQ shares have all but fallen off the chart in response.

Act IV: It's all in a name

The Player: Harry Winston Diamond Corp. (TSX:HW) Action: Down nine per cent or $3.98 in a month (from $42.08 Oct. 19) Recent Price: $38.10 52-Week High/Low: $48.36/35.21 When strolling the red carpet, you never hear a star answer, "Who are you wearing?" with "Aber Diamonds."

So it's no wonder when the famous jeweler recently launched on the New York Stock Exchange (NYSE: HWD) to complement its TSX listing, the company officially changed its name to Harry Winston Diamond Corp.

The NYSE launch was celebrated in true Harry Winston style, when models wearing millions of dollars worth of diamonds walked the trading floor at the NYSE's opening bell ceremony.

Harry Winston, the international diamond enterprise with interests in both the mining and retail segments of the industry, supplies rough Canadian diamonds to the global market from its 40-per-cent interest in the Diavik Diamond Mine in the Northwest Territories.
