An exciting week of cricket passed by with fantasy shareholders reaping the rewards. It was all about the BBL playoffs as the Sydney Sixers marched on to the final at the expense of the Perth Scorchers. However, the Scorchers will have another go at making the final as they face the Heat later this week. All eyes will be on Jason Roy and co as they seek to make a difference in this all-important game. As the build-up to the BBL final and the much-awaited England tour of India gets underway, a knowledge of the recent happenings in the Market is on the cards. Without further ado, here are the top Bulls and Bears of the Week in the Sixer Market!Bull #1: James Vince (Sydney Sixers)Price: 56.60 Sixer Coins; Price Change: +46.97%Who else but James Vince?! The Englishman was on fire for the Sixers during the week with a match score average of 117.49. The carnage started at the MCG as Vince, who has been promoted to the top of the order, smashed a 32-ball 46 in what was a terrific display of ball striking. But if that wasn't enough, fantasy shareholders need to look only as far as the Qualifier of the BBL playoffs. In what was supposed to be a tricky chase at the Manuka Oval, the Sixers overseas recruit smashed his way to 98*. He registered a perfect match score at the time of need, helping his fantasy stock price go up by 46.97%! Considering this stock price currently reads 56.60 Sixer Coins per Share, Vince is in prime position for a further increase in the all-important final as well. Will he deliver the goods yet again? Only time will tell!Bear #1: Chris Lynn (Brisbane Heat)Price: 56.60 Sixer Coins; Price Change: -16.07%Another player whose fantasy stocks currently trade at 56.60 Sixer Coins per Share, Chris Lynn makes the cut as a Bull in this week's insight! Although the Heat is through to the final three, Lynn has failed miserably in the playoffs so far. Coming into the final week on the back of a stunning fifty against the Scorchers, Lynn hardly scored 20 runs in the two games so far. This has caused his price to drop by 16.07%. He has averaged a match score of 18.51 although it shouldn't deter him or his fantasy stockholders too much. What may worry them is the fact that the next Heat game is at the Manuka Oval, a venue that has played well with Lynn. However, Lynn is too good a player to miss out on in the Market. With a place in the final beckoning, getting Lynn into your portfolios, ahead of the PSL as well, would make perfect sense in the Market!Bull #2: Paul Stirling (Ireland)Price: 63.30 Sixer Coins; Price Change: +47.22%Moving away from the BBL for this one, we have Paul Stirling making the cut as the second Bull of the Market. Against a strong Afghan bowling unit in the UAE, Stirling had a stellar series with two hundreds and 100+ match scores as well. He showed the way in terms of dealing with mystery spinners Rashid and Mujeeb, both of whom found it hard going against the Irishman. Stirling averaged a match score of 132.43 in the two games over the weekend, higher than that of James Vince. Stirling has shown the same form over the last few months with only one match score of 50 or below in his last nine outings. With the Irishman also being lauded for his ability against quality spin, we might well see him in the IPL sooner rather than later!Bear #2: Jhye Richardson (Perth Scorchers)Price: 62.70 Sixer Coins; Price Change: -10.61%Speaking of possible IPL recruits, Jhye Richardson is surely high on the wishlist. The current leading wicket-taker in the BBL, Jhye Richardson has been a sensation this season with 27 wickets. However, the lanky pacer hasn't been at his best lately with a price drop of 10.61%. Although he averaged a match score of nearly 36 over the week, he picked only one wicket, which also affected the Scorchers. They lost both their games during the week and would be desperate to get the W against the Heat later this week. Jhye, who has four man-of-the-match awards and five scores of 100+ this season, is crucial to their chances of making it to the playoff. Given how the Manuka Oval has favoured pacers early on, his fantasy price of 62.70 Sixer Coins might actually be a bargain given time. With the New Zealand T20Is also fast approaching, now might be the time to bank on Jhye's unparalleled wicket-taking ability!
