The S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) has built on yesterday's solid gain and is on course to finish the week on a positive note. At the time of writing the benchmark index is up a further 0.55% to 5,627.3 points.
Four shares that have climbed more than most today are listed below. Here's why they are ending the week on a high:
The Artemis Resources Ltd (ASX: ARV) share price has surged almost 14% higher to 12.5 cents despite there being no news out of the mineral resource exploration company. However, its shares have fallen hard this month and some investors may believe they have bottomed now. Artemis owns the Radio Hill Nickel Mine in the West Pilbara region of Western Australia.
The Atomos Limited (ASX: AMS) share price is up 12% to 46 cents. Atomos is a global video technology company delivering award-winning, simple to use and affordable monitor recorder content creation products. It arrived on the Australian share market this morning with a listing price of 41 cents, valuing the company at $62.2 million. This year it expects to achieve pro forma revenue of $42.2 million, up 18.5% from $35.6 million in FY 2018.
The BWX Ltd (ASX: BWX) share price has risen 9.5% to $1.53. The personal care products company's shares have been hammered this month after a surprise profit guidance downgrade. While I'm not prepared to make an investment just yet, its shares do look great value for those that are willing to bet on the company successfully turning around its poor performance.
The Orocobre Limited (ASX: ORE) share price has jumped 9% to $3.29. Investors appear to believe that the recent selloff of this lithium miner's shares has created a buying opportunity today. Orocobre's shares were hammered earlier this month when it revealed a sharp drop in the price of its lithium in the December quarter.
