What a week it was in the world of cricket! Domestic cricket across Australia, New Zealand and South Africa gave fantasy shareholders a few moments to cherish while Shai Hope starred in a three-match ODI series against Sri Lanka. Not to mention, we witnessed one of the best T20I series in recent memory as India beat England by a whisker. All of this had a profound effect on the Sixer Market, which is where we begin this week. Here are all the top performers and underwhelmed over the past week in this week's Bulls and Bears Insight!Bull #1: Virat Kohli (India)Who else but the King himself? Virat Kohli was adjudged the man of the series in the T20I series and is now the Bull of the Sixer Market. Although Virat started the series with a duck, his price has gone up by 37%, courtesy of three fifties in four games. Virat also registered three 100+ match scores in four games, which the first time he has done so in two years. He ended up as the leading run-scorer in the series with 231 runs. With the Indian captain already confirming that he will open the batting for RCB in the IPL next month, his fantasy shareholders will be licking their lips at that prospect. Nevertheless, he is in action in the ODIs later this week, which provides another opportunity for an increment. Will his price increase further from 65.40 Sixer Coins per Share? Only time will tell!Bear #1: Eoin Morgan (England)From one international-cum-IPL captain to another, Eoin Morgan didn't have the best of times in the T20I series. While he didn't get to bat in one game, his returns in the others were poor. As a result of a match score average of 26.82, Morgan's price has dropped by 20% to an all-time low of 39.90 Sixer Coins per Share! Despite Morgan being England's enforcer in the death and not to mention a good player of spin, he wasn't able to deliver at the Motera. However, the English captain will get another go in the ODIs as he tries to cover some lost ground in the Sixer Market. With the IPL also just around the corner, the best of Eoin Morgan could well be upon us in the Sixer Market!Bull #2: Jackson Bird (Australia)Who would have thought Jackson Bird would stand out as the Bull of the Market this week? While many fantasy shareholders missed out on him, a select few were able to grab him up before his stellar increase of 18.80% on Sunday alone. Jackson Bird picked seven wickets against New South Wales as they were bundled out for a paltry 32. Bird registered a match score of 105, which is currently the highest in the game. At 57.00 Sixer Coins per Share, Jackson Bird is nicely placed for another increment in the Market. Given that he is one of the best bowlers in the Sheffield Shield, he might well be worth the investment in the coming days!Bear #2: KL Rahul (India)Last but not least is KL Rahul, albeit as a Bear in this week's insight. The KXIP captain has slumped to an all-time low price of 41.80 Sixer Coins per Share over the last week. He hasn't scored as many runs as he or his fantasy shareholders wouldn't like, with a match score average of 16.19 to show for his efforts. This handed him a 27.80% decrement over the week, which has happened for the first time this year. Although it is just a matter of time before Rahul showcases his class, there are some concerns over his form. Like Morgan's case, Rahul should ideally have a better experience in the ODIs with the wicket-keeper batting at number five. With a change in scenario and role in the batting order, Rahul could see a massive increment before the IPL starts! Watch our for new stocks at 2:00 PM, although it is a dogfight in the Sixer Market for his fantasy stocks!
