Another week passes by, but this time around, the Sixer Market activity has left us awestruck. Although the BBL has come to an end, it did leave us with a couple of James Vince specials towards the end, something that we would dive into a little more later on. But with the week done and dusted and as India continues to grind it out in Chepauk, here are the Bulls and Bears of the Week!Bull #1: James Vince (Sydney Sixers)For the second week in the row, it's that man James Vince, who stars as the Bull of the Sixer Market. If last week was outstanding for the Englishman's fantasy shareholders, Vince went up a notch with two perfect match scores to his name against the Perth Scorchers. He scored 98* and 95 in the BBL finals to led his side to the BBL trophy although this was just the icing on the cake. His fantasy stock price rose by a whopping 53.39% as he became the first player after Shikhar Dhawan to register two 150 match scores in consecutive games since the start of 2020! But this could be the start of something big as Vince is all set for PSL action later this month. With the Englishman having a decent campaign last time around in Pakistan, there's no telling how impactful he can be this time around. With his fantasy stocks trading at 67.60 Sixer Coins per Share, there's certainly a possibility for an increment in the PSL!Bear #1: Quinton de Kock (South Africa)Moving over to the Test format, the South Africans are in a fight for redemption in the second Test against Pakistan. They are chasing a 300+ score, and key to that run-chase will be Quinton de Kock. However, de Kock hasn't been in the best of forms for the South Africans off late. The wicket-keeper's stock price has dropped by nearly 8% with a match score average of just 34.75 over the last week or so. Although he is due for some action in this Test, de Kock has struggled to convert his starts, which was a major problem during his initial days as a Test match cricketer. Against the likes of Shaheen Afridi, de Kock will need to come up with the goods if RSA were to come anywhere near the target. As for his stocks in the Sixer Market, they currently trade at a reasonable price of 51.20 Sixer Coins per Share, which might draw a few shareholders to him. But only time will tell as to how effective he can be for the Proteas!Bull #2: Liam Livingstone (Perth Scorchers)There's another Englishman on this list as the Bull. Although he didn't achieve a perfect match score as Vince, Liam Livingstone certainly played his part in the Scorchers' run to the final. In two do-or-die matches, Livingstone top-scored for the the Scorchers with his fantasy price increasing by 18.51%! While his whirlwind fifty against the Heat earned him a 100+ match score, Livingstone nearly gave his side the perfect start against the Sixers before succumbing before reaching a fifty. Nevertheless, he managed to end up with a match score average of 107.98, which was second only to James Vince and Joe Root over the week. With Livingstone now signalling his intentions in the T20 format, we could well see a lot more of the Lancashire batsman in franchise T20 leagues and perhaps in England colours as well!Bear #2: Rohit Sharma (India)Now back to the keenly watched India vs England Test! We've already seen some wonderful knocks from Joe Root and Rishabh Pant, but there's the curious case of Rohit Sharma, who couldn't last too long in the second innings. The Mumbaikar makes the cut as the Bear this weak courtesy of his no-show with the bat. Rohit's price dropped drastically by 5.60% during the weekend with a match score of just 31.83! But this isn't something to worry about in the long run. We're only halfway through the first Test in a four-match series, which leaves a lot of room for an increment. Like his Mumbai Indians opening partner de Kock, Rohit's fantasy shares are also trading at 51.20 Sixer Coins per Share, likely to draw a lot of eyeballs to it. Will he be able to overturn his fortunes in the long run? Your guess is as good as anyones!Waiting for new stocks to arrive in Pujara, Rahane and Finch?
