The Sixer Market didn't disappoint in terms of activity in the final week of February. Cricketing action across New Zealand, Australia, India and Pakistan saw a couple of superstars such as Mohammad Rizwan topple the Sixer Market charts. For some it wasn't as rosy with Glenn Maxwell failing to get going in the T20Is. We even saw a couple of 150 match scores courtesy of Sharjeel Khan, Martin Guptill and Marcus Stoinis in the T20 format. But only a few make the cut as this week's Bulls and unfortunately the Bears. Here's some much-needed insight to kickstart your week!Bull #1: Usman Khawaja (Australia)Usman Khawaja is this week's top asset in the Sixer Market and why not. The southpaw scored two hundreds in two different formats, helping his fantasy stock price up by 20.79%. With a match score average of 76.55 during the week, Khawaja's price nearly breached the 50-Sixer Coins barrier. Trading at 48.40 Sixer Coins per Share, Khawaja is in for a bigger increase if he continues his current form. Only time will tell as to how far Khawaja can soar in the Market!Bear #1: Colin Ingram (South Africa)Much was expected of Colin Ingram ahead of the Super League. For starters, Ingram was traded by the Kings from Islamabad for his experience and ball-striking ability. But Ingram is now available for an all-time low of 36.50 Sixer Coins. He could only muster a match score average of 19.91 across the week, something his fantasy shareholders wouldn't be too happy about. With his price dropping by 11.81%, Ingram and his fantasy stocks present an intriguing case for a trade in the Market. But will potential fantasy shareholders back the 'Bulldozer'?Bull #2: Cameron Green (Australia)Someone that was heavily backed in the Sixer Market, Cameron Green finally repaid the trust and faith with a sensational hundred during the week. With a match score average and price increase of 78.74 and 21.74% respectively, Green's fantasy shares soared in the Market. Against a strong South Australian bowling attack, Green held the fort for WA as they held on for a famous draw. With his fantasy shares trading at a modest 36.20 Sixer Coins per Share, Green should find more bidders over the next few months. But with the talent that he possesses, we should see a lot of him in these lists!Bear #2: Kyle Jamieson (New Zealand)Last but not least is Kyle Jamieson, whose no-show in the ongoing T20I series earns him the tag of the Bear. In two outings for New Zealand, Jamieson could only manage a match score of 18.65, resulting in a 21% decrease in fantasy stock price value. These performances came on the back of a multi-million deal in the IPL Auction, which adds further doubt to his ability. However, Jamieson has been one of the breakout stars in world cricket over the last year. With his ability to extract extra bounce and also his added batting value, he is surely one to keep an eye out for in the Market!
