Bargain hunters have helped to push the S&P/ASX 200 (Index: ^AXJO) (ASX:XJO) higher today with a gain of 0.72% to 5,448 points.

The property, industrials and information technology sectors have been the best performing sectors today, with the gold sector being the biggest laggard.

Four shares that have been particularly strong performers today, include:

Aconex Ltd (ASX: ACX)

Shares of Aconex have surged more than 10% after the construction software company provided a positive update at its AGM today. Impressively, first quarter cash receipts came in at $41.8 million – an increase of 41% over the prior corresponding period. Management also provided a positive outlook for the remainder of FY17 and expects revenue to grow to between $172 million – $180 million, up from $123.4 million in FY16. Some of today’s strong gains can also be attributed to short covering, considering around 8% of Aconex’s shares are in the hands of short sellers.

Automotive Holdings Group Ltd (ASX: AHG)

Shares of Automotive Holdings have climbed more than 4% today mainly on the back of media speculation that has suggested the company may be in the process of divesting its underperforming refrigerated storage and logistics business. The company has confirmed it has received expressions of interest for the business, although it has not initiated a formal sale process just yet. Judging by today’s reaction however, investors would support the move as the division has been a major drag on the company’s earnings over the past couple of years.

Sirtex Medical Limited (ASX: SRX)

Shares of Sirtex have risen by more than 3% after the cancer treatment company provided an upbeat outlook at its AGM today. Following on from a strong FY16, management expects another year of double digit dose sales growth, along with the results of three major clinical trials. Sirtex also flagged the possibility of expansion into new territories and has also appointed 14-year company veteran, Nigel Lange, as its new Chief Operating Officer.

Greencross Limited (ASX: GXL)

Shares of Greencross have spiked 5% today after the veterinary and pet care company provided a healthy trading update at its AGM. The company is on track to deliver all of its store network targets and also noted that trading conditions had improved in September and October. Group like-for-like sales have grown by 3.9% for the year to date and the company expects to deliver net profit after tax (NPAT) growth of around 10% in FY17.
